Hey Captain Joe, I'm a R&D engineer at a big aerospace company in the U.S. and I love your content! I'm a new follower and really enjoy how informative and well explained your videos are! Edit: Should have waited for the video to end. I worked on the Q-400 briefly and the boots on the tail have to do with tail sizing and power. Using boots outweighed the weight increase from needing to size up the tail and H-stabs for min control speeds. For anyone who is a bit more curious about why the electrical de-ice on the 787 is superior to bleed air, it's all in the thermodynamics. An electrical generator will convert its motion to electricity at a very high efficiency (low losses), of which is much better than energy loss in the pipes going to the critical surfaces (despite the insulation) and heat transfer losses in the convection within the leading edges. Those losses are also compounded by the fact that the engine needs to work harder to make up for the pressure loss the anti-ice system imposes. Again, an electrical generator tapping energy off the engine is way way way more efficient (can be an order of magnitude) than taking that pressure out of the compressor and relying on convection for heat transfer.
Regarding your question at 7:40. Smaller aircraft like turboprops are often right short (in relation to the fuselage diameter and wing span). Due to the short distance of force to the center of gravity, the controllability around the yaw and pitch axis is lower as for are longer aircrafts. In icy conditions, the airflow around stabilizer and elevator is disturbed. Therefore, the controllability is reduces (required forces can not be produced anymore). Either a bigger stabilzer and elevator is needed the reach better performance in ice conditions (to compensate the force-loss in icy conditions), or boots prevent the build-up of ice to reduce these effects. Btw: First time seeing a boot in action! Thanks for sharing! Best regards, an aerospace engineer master student.
Baureihe711 I was thinking that it was only because the smaller aircraft are more sensitive to the shift of the center of gravity due to the weight of ice on the tailplanes. But I think your answer is better.
I've heard they used to employ gremlins on the wings to break up the ice during flight, but after that unfortunate incident with William Shatner they had to let them go and install hot air ducts instead...
I'm always amazed how accessible his videos are. Even with some really technical topics, he always manages to make it understandable. Keep doing what you're doing Captain. Always a pleasure to watch your videos !
This was a really interesting episode, I was already aware of the dangers of ice accumulation and the existence of de-icing equipment, but always figured they were powered by electricity. And while the bleed-air technique makes a lot of sense, the way the rubber boots are used on turbo-prop planes is a very inventive way to get around their limitations. I'd definitely like to see more of these in-depth technical videos!
They say you only really know a topic or something well when you can explain it simply. This is one of the simplest explanations I’ve come across. Nice work! Hope you’re enjoying the 748!
I’m not a pilot but I’ve traveled a lot for work over the past 30 years. I have one of those minds that always likes to know the “how” and “why” of everything. Your videos have answered so many of those how-and-why question puttering about in my head. Thanks!
Hey Joe, I've been watching your videos for some time now, just wanted to say how I appreciate your effort and love the things you do. Take care man!!!
For what reason have 265 people left a "Thumbs Down" on this video? Joe IS an experienced qualified First Officer on numerous aircraft, so he knows what he's talking about. This makes him more qualified than most to put out videos on aviation..... bunch of knobbers.
I fly the B1900D. There are a lot of small horizontal and vertical stabilizers in the tail section that were added on for stability when they certified the plane. These all have de-ice boots, however the main vertical stabilizer with the rudder has no icing system whatsoever. It just doesn't need it. As for the rest, they added the boots just for safety. The 1900 is an excellent plane in icing conditions.
Hi Joe, I'm new to your channel, subscribed yesterday, I must say your enthusiasm and love for your job while teaching others made it my favorite channel, keep up the great work, Look forward to much more content like this. Cheers
I'm a mechanic on C-135 model aircrafts for the US Air Force, and they have an inlet on the vertical stab that heats up incoming air and pumps it into the stab to keep the mechanical parts that move the rudder from accumulating ice.
Captain Joe thanks for the excellent vids, they are truly first class and very informative. A request: Could you do a video about navigating waypoints over the ocean?

Just wondering, runways have some treatment in snowy icy days? Or when freezing rain is happening? What is happening when takeoff or land on icy runways?
De-icing operations for airport pavement (runways, taxiways, aprons, taxiway bridges) may involve several types of liquid and solid chemical products, including propylene glycol, ethylene glycol and other organic compounds. Chloride-based compounds (e.g. salt) are not used at airports, due to their corrosive effect on aircraft and other equipment. Urea mixtures have also been used for pavement de-icing, due to their low cost. However, urea is a significant pollutant in waterways and wildlife, as it degrades to ammonia after application, and it has been largely been phased out at U.S. airports. In 2012 the U.S. Environmental Protection Agency (EPA) prohibited use of urea-based deicers at most commercial airports. The chemicals end up leaving a wet surface and not an icy one. Aircraft movement areas are not smooth but are brushed to increase tyre grip.
Great summary. Just a note- The super efficient 747-8 wing does have wing anti-ice between the root of the wing and the engine. Also most engine anti-ice systems use a single swirl nozzle to distribute engine bleed air.
Hey Joe love the videos, want to become a pilot myself and you certainly inspire me to be one. Love the knowledge I’m getting on aviation just by watching your videos!!

Turbo prop planes statistically spend more time in icing regions of flight. They are trimmed with trim-tabs not adjustable stabilizers (non-flying tail) and antiquated designs. Next gens would have heating mats incorporated. The slower speeds are also more conducive to build ups.
Thanks a lot for this video, this was exactly the ATPL chapters I was studying yesterday in my books and I really needed to visualize it ! So crazy that this exactly subject appeared in my suggestions today ! The world is sometimes very well done =D
Hi Joe, fantastic. Just to remind that icing can also affect the windshield if it's not heated properly and could lead to a discomfort situation while landing with little or bad visibility through it. Best deal is to fly away from icing conditions whenever it is possible. Thank you

Another channel actually has an Airbus pilot flying and landing a Boeing simulator, and although it was weird, and he needed some time to find buttons (and a lot more was analogue), he managed fine, and even got a compliment for a decent landing. =)
A couple of things...1. Great video! Who in the hell are the people giving it thumbs down??? 2. Great reference to Agent Jay Z for the engine anti ice. His series of videos are excellent for anyone interested in learning about gas generating turbine engines (jet engines).
It isn't? It pretty much looks like a LH aircraft. The grey nacelles, the recent ocurrences in the german market. What airline is is then? Thanks for the quick reply though.
The only anti-ice/de-ice my little plane has is carburettor-heat, which uses hot air from around the exhaust manifold to warm up the intake air. I'm not allowed to fly into known icing conditions, and I try not to fly into icing conditions, ever. I have, however, flown over snow-covered landscapes, which is awesome!
joe, ive heard that there is some airline that gives you CPL in exchange of a 10-year contract, and when you start paying them when you start working, is that true if so which airline does that, cuz i did my research and i haven't seen any, thank you
Dan thank you ill look it up, cuz i really want to be a pilot and im willing to do the impossible for it, im still young tho, im 18 so i still have time,
Hi, the reason is the low velocity of the AV. The controllability is more sensitive because of low speed aerodynamics. Airliners have much higher T/O velocities and cruise at roughly mach 0.8 or 0.85. Of course while cruising the airplane is so high that you don’t have to worry about ice accretion (no humidity). I actually deal with such systems in my line of work (I’m an aerodynamicist) so I know a thing or two. Cheers 🖖🏻
comair 3272 Waited for the ice to build up and thus crashed. The NTSB determined that anti ice boots shall be deployed immediately after ice accumulation. Ice "bridging" is a myth. On another note, great video! keep up the good work Joe.
Hi Joe, I'm a follower from Taiwan. Can you do a video about how you pay for your flight school which you mentioned at you video 4 months ago on "10 reasons not to become a pilot." Love to watch your videos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Turbo props have de-icing boots on the leading edge of the wings and even on the vertical stabilizer and horizontal stabilizers because the turbo props are much slower than jet liners plus they fly at a lower altitudes where the ice can occur instantly and this can have a fatal effect on the tail plane. The jets on the other hand fly quickly through the weather and cruise above it so for this reason they dont suffer from same continuous exposure to ice and therefore they don't need any heating systems in the tail plane. And I really enjoy your videos capt. :)
Hey Captain Joe, may I suggest that you refer to the air crash investigation episode of British Airways 38 when you do get round to making this video. Very nicely detailed documentary.
There were another ATR fatal crash a month ago in Iran. It crashed during approach phase while weather was freezing and snowy. Airplane was built in 1992 and had not received de-icing system upgrade which is presumably the cause, though inspection is going on.
Gixer750pilot Now it's 23 thumbs down i wish i could find these people and ask them why they give thumbs down. I think most are just jealous, there is people out there that can't stand successful people because their life didn't work out for them so they will do anything to see others fail and some thumbs down might just be a mistake. But most of thumbs down are probably by some 50 year old loser still living in his mothers basement and can't stand Joe's success.
Im pretty sure the reasons why turboprops are fitted with deicing boots are; turboprops usually have reversible, directly linked, controls. they are more prone to tailplane stalls and ice accumulation, ice build up tends to cause the elevators to move down due to the airflow. Also, they fly slower and the elevator trim is on the elevator itself, unlike airliners where the trim is moving the entire horizontal stabilizer.
I've flown a Dornier 228. The horizontal stabilizer and fin in case of ice tend to loose effectiveness and the ice build tends to be more fatal due to the shorter arm between the center of the airplane and the tail therefore it has to be protected. The tail on the do228 was made of fabric like the wings on a cub but they all had rubber boots
Man planes are so complex yet we take them for granted despite being engineering marvels it’s also great that we have the internet to be able to share this info
Joe, I enjoy your videos. This one was like watching a systems CBT, except you are not boring or dreary! Actually I wanted to add that my jet (MD-80) does have de-ice system on the leading edge of horizontal stabilizer. We activate it every 20 minutes, after exiting icing condition, or 1 minute prior to extending tail flaps. It runs for 2 1/2 minutes, and the wings do not get heated while tail de-ice is operating. I imagine all DC-9 variants have that system. While no one is sure why we have that system, my educated guess is due to unique design of DC-9 flight controls. Our elevators are not hydraulic. They are flown by aerodynamic tabs. When I move the yoke, it only moves the tab. In turn, the aerodynamic momentum flies elevators just like the trim tab does on a 172. Because of it, we are susceptible to tail icing phenomenon. I think the tail de-ice is supposed to prevent loss of controllability due to tail icing.
So much information! Thank you from Zakarpattia, Ukraine! Even with this cool accent I understood almost whole speech. Greetings and good luck in the air 🙂
Interessant und gut gemacht. Aber ehrlich ich glaube nicht das das E - Deicing System auch nur ein Gramm Treibstoff spart, ersten brauchts ne ganze Menge Strom, zusätzlichen oder größeren Generator , und ein Generator bremst die Leistung der Motoren ganz erheblich , es wäre mal interessant wie das System von BOING aussieht, aber wie immer kommen nur große Worte und am lautesten Trommeln damit es auch jeder glaubt, wie bei einer bek. E -Automarke auch nichts dahinter.
1. Bei dem Air Bleed System fehlt die Luft die zum Enteisen genutzt wird dem Antrieb. (Abgezweigte Luft reduziert ebenfalls die Leistung) 2. In dieser Luft steckt viel mehr Energie drin als benötigt wird, sie muss ja auch erst auf verträgliche Temperatur runtergekühlt werden. 3. Es kann nicht ganze Temperatur der Luft zum enteisen genutz werden, d.h. es geht einiges an Energie ungenutzt verloren Bei E-Deiceing fällt das Air Bleed System und damit auch sein Gewicht weg. Man muss viel weniger Energie aufwenden um den selben Effekt zu erzielen, die Flügelkanten werden ja nur soweit aufgeheizt, das sich kein Eis bildet und dafür müssen sie nicht auf 200°C aufgeheizt werden
Stimmt schon, das Gewicht fallt weg , aber Alu - ist leichter wie Kupfer, Widerstandsdraht braucht ne Menge Energie, Die heiße Luft wird bei dem Airbleed system sowie so schon heruntergekühlt. Zweitens jeder weiß das Diesel,- elektrisch, oder mit Benzin, oder Kerosin elektrisch angetriebene Generatoren um elektrische Antriebe oder Verbraucher anzutreiben im Gesamt Wirkungsgrad schlechter sind als die Direktabnahme , Die Physik lässt sich nicht verändern, auch nicht für Boing. die Flügelkanten müssen so weit aufgeheizt werden das sich kein Eis bilden kann, 35000f bei ca 900km/h Temp von -50 Grad and den Flügelkanten ist einige Grad kälter, also mit 50 Grad plus kannst du die Flügel nicht Eisfrei halten
Es gibt auch Alu-Kabel, die auch schon in der Luftfahrt eingesetzt werden. Wenn du ein Ei kochst, was hat den besseren Wirkungsgrad, wenn du das Wasser auf 100°C erhitzst oder wenn du erst in einem Kessel das Wasser verdampfst, den Dampf auf 600°C bringst und dann wieder auf 100°C abkühlst? Bei der Direktabnahme ist der Wirkungsgrad nur dann besser wenn nur soviel Energie bereitgestellt wird wie benötigt wird. Bei einer Flugzeugturbine wird ja nicht einfach nur ungenutze Abwärme wie beim Auto genutzt.
Alu Kabel sind wesentlich schlechtere Stromleiter um die selbe Wattzahl durch das Kabel zu leiten muss das Kabel wesentlich stärker sein , ca doppelte mm/2 zweiten ich wärme ja nichts auf extra, für das Antiicing, die wärme wird so oder so produziert, Bleedair wird auch benutzt um den Kabinendruck zu erzeugen und gleichzeitig eine angenehme Temperatur in der Kabine zu erzeugen , oder sitzen Sie im Flugzeug, mit Winterjacke ,Bempelmütze und Handschuhen und frieren sich trotzdem den Arsch ab.Also die Bleedair wird so oder so heruntergekühlt , der Trick besteht darin den richtigen Abgriff zu setzen um so wenig wie möglich Energie zu verbrauchen.AluKabel sind die schlechteste Wahl, in Hausinstallationen sind sie verboten , die Oxidation des Aluminiums verschlechtert den Widerstand an den Kontaktstellen ganz erheblich, durchgebrannte Kabel oder Kurzschlüsse wären nur eine Frage der Zeit , ich glaube nicht das man die in Flugzeugen verwendet oder verwenden darf, Sie altern auch viel schneller. Sollte Boing solche Kabel verbaut haben , gebe ich Ihnen den guten Rat nicht in eine Boing zu steigen. Aber wie es so ist man kann diskutieren wie man will, ich weis nicht was Boing benutzt und wie das System im Detail aussieht. Für mich sieht es so aus das die Verbrauchswerte schön gerechnet sind um Vorteile beim Verkauf zu haben, solche Rechnungen hat man in allen Bereichen auf dem Papier sieht es gut aus in der Praxis ist es dann ganz anders, da ist halt der Pilot, oder das Wetter daran Schuld wenn der Flieger plötzlich mehr Treibstoff braucht als auf dem Papier vorgerechnet, es wird nur das Optimum angenommen ,nachher kann das sowieso keiner 100% ig nachprüfen weil die realen Flugdaten erheblich abweichen . Wi auch immer , ich wünsche ein schönes Wochenende .
Das Bleedair für Kabinenheizung fällt ja auch weg. Auch mit größerem Querschnitt sind Alukabel immernoch 40% leichter. Und es gibt extra für Alukabel entsprechende Anschlussstücke, luftdicht und mit Kontaktfett das Korund enthält um oxidation zu vermeiden. Im A380 werden Alukabel verwendet
I'm an aviation meteorologist, and I understood that the anti-icing boots on the horizontal stabilizers were because of the smaller radius diameter of the tail plane when compared to the main wings. Smaller radius objects get a disproportionately larger buildup of ice on them. So if ice is building up on all the wings, the (relatively) larger buildup on the horizontal stabilizer will lead to tail plane stalling before the main plane does, thus (in most cases), pitching the aircraft nose-down into a dive. This happened in a Convair crash in New Zealand resulting in the aircraft breaking up in flight (due to exceeding VNE) and the loss of life of the pilot and co-pilot
Bridging is not a problem for Propeller Planes now. Rubber Tubes inflate and deflate rapidly and prevent Ice Bridging. Old Propeller Planes had Ice Tube that used to inflate and deflate slowly and this used to cause Ice Bridging. So new planes do not have to wait for ice build up. they can activate ice boots at first appearance.(Boots inflate and deflate rapidly removing ice)
I think because, in small airplanes like turboprops, the controllability is a lower and with the "cooling plus", is more lower. the icing-boots prevent the build of ice in.
Thanks for the video! I just watched it because I didn't understand why the inboard part of the wings leading edge isn't heated. Gave me some good information for my aircraft subsystems university exam next week.
I believe that the waiting time for deice Boots activation is nowadays a myth. It mostly applied to older boot systems. Modern deicing boots are deployed at very high speed thus preventing bridging effect and in manuals it is requested for pilots to activate the system immediately after visible accumulation of ice and not calculating waiting time.
I'd apply the deicing systems frequently to prevent icing. Liquid deicing is another efficient way for small plaes. Elevator icing won't be a big issue unless the control systems got hard over.
Carbureted planes can get their carburetors frozen, restricting the fuel flow, and eventually causing an angina failur. Below 2,000 RPM, in IMC or in icy conditions, we have a lever next to the thrust lever we pull out to electrically heat the walls of the carburetor. While its on however, engine rpm drops drops a little bit due to the increased temperature
Joe don't forget the fabulous 50s! The DC-6, DC-7 and C-123s used a combustion heater inside the wing to generate hot air for the wing leading edges. That's right! there was a souce of fire inside the wing surrounded by all that fuel. I bet this was checked VERY carefully in pre-flight.
Thank you Captain Joe. Your presentation and speaking style are impeccable! I find it useful to consider your style when I have to present something and I don't even work in the aerospace industry.
Thank you!!! The BEST video yet! Please make more on systems! Sincerely, AMT student. Pressurisation systems, air-conditioning, Fire & extinguishers Etc.
Some of the melted ice is directed to the aft cargo door ice water inlet valve doodad where there is a water cooler. The water is then recooled via vortex generators and the resulting ice is used as cubes for the mixed drinks for the pilots, crew, and happy passengers.
I would love to see a video explaining how trim control works, why you not use it or why not to often and why it does 180/360 turn when there is an autopilot etc.
Hey Captain Joe, I'm a R&D engineer at a big aerospace company in the U.S. and I love your content! I'm a new follower and really enjoy how informative and well explained your videos are!
Edit: Should have waited for the video to end. I worked on the Q-400 briefly and the boots on the tail have to do with tail sizing and power. Using boots outweighed the weight increase from needing to size up the tail and H-stabs for min control speeds.
For anyone who is a bit more curious about why the electrical de-ice on the 787 is superior to bleed air, it's all in the thermodynamics. An electrical generator will convert its motion to electricity at a very high efficiency (low losses), of which is much better than energy loss in the pipes going to the critical surfaces (despite the insulation) and heat transfer losses in the convection within the leading edges. Those losses are also compounded by the fact that the engine needs to work harder to make up for the pressure loss the anti-ice system imposes. Again, an electrical generator tapping energy off the engine is way way way more efficient (can be an order of magnitude) than taking that pressure out of the compressor and relying on convection for heat transfer.

Can you do a video about the emergency kinds please ;)?
AviationPRO He has
He has already made a video about this. Look further down his videos :)
he already did that
Great Minds think alike Freckless057 and Thomas Mortimore hehe
XD
Has a frequent flyer your videos makes me understand the little details of the environment I live in. Just awesome!
As an airbus pilot, have you /would you be able to fly a Boeing aircraft?
If he made the typerating: Yes, theoretically.
Yep with the rating sure which is why you have seen him in Boeing simulators more recently, the more type ratings you have the marketable you are.
Give me one month of typerating and I guess I´d be fine!
Another channel actually has an Airbus pilot flying and landing a Boeing simulator, and although it was weird, and he needed some time to find buttons (and a lot more was analogue), he managed fine, and even got a compliment for a decent landing. =)
Captain Joe would the yoke throw you off on a Boeing, because it is very different than a side stick on an Airbus in my opinion?
A couple of things...1. Great video! Who in the hell are the people giving it thumbs down??? 2. Great reference to Agent Jay Z for the engine anti ice. His series of videos are excellent for anyone interested in learning about gas generating turbine engines (jet engines).
i agree...AIRBUS step-up your game !!
Yes they should ;)
Yes they should ;)
What it means?
It means that boeings system is more advanced than the one of airbus and airbus should keep up to remain competitive.
Its a french thing. Like their cars, they have rarely been innovative or begun using new tech the last 30yrs. Might even say they're crappy
I weld and assembly the De-icing tubes for Boeing. very tight tolerances for a tube
Has anyone else noticed how the aircraft on the thumbnail is a Lufthansa one?
Has anyone noticed that that isn´t true?
It isn't? It pretty much looks like a LH aircraft. The grey nacelles, the recent ocurrences in the german market. What airline is is then? Thanks for the quick reply though.
Maybee, just maybe it could be a Eurowings aircraft ;)
The only anti-ice/de-ice my little plane has is carburettor-heat, which uses hot air from around the exhaust manifold to warm up the intake air. I'm not allowed to fly into known icing conditions, and I try not to fly into icing conditions, ever. I have, however, flown over snow-covered landscapes, which is awesome!
6:30 okay then just casually do a vertical, sure
lol
I really like how you film and plot your videos, short but your point is very understadable. Keep it up!
joe, ive heard that there is some airline that gives you CPL in exchange of a 10-year contract, and when you start paying them when you start working, is that true if so which airline does that, cuz i did my research and i haven't seen any, thank you
I think Finnair has a program like this.
Dan thank you ill look it up, cuz i really want to be a pilot and im willing to do the impossible for it, im still young tho, im 18 so i still have time,
What is CPL?
CPL= Commercial Pilot Licence
PPL= Private Pilot licence and ATPL= Airline Transport Pilot Licence
Hi, the reason is the low velocity of the AV. The controllability is more sensitive because of low speed aerodynamics. Airliners have much higher T/O velocities and cruise at roughly mach 0.8 or 0.85. Of course while cruising the airplane is so high that you don’t have to worry about ice accretion (no humidity). I actually deal with such systems in my line of work (I’m an aerodynamicist) so I know a thing or two. Cheers 🖖🏻
1:47 FSX: Steam edition right there xD
Irritated Camel / Roblox Stuff p3d
comair 3272 Waited for the ice to build up and thus crashed. The NTSB determined that anti ice boots shall be deployed immediately after ice accumulation. Ice "bridging" is a myth. On another note, great video! keep up the good work Joe.
Great video! Can we get a video on stall prevention and spin recovery?
Yes next spring, not flying smaller planes at the moment!
Captain Joe great! :D
i am only 13 and i have a big passion for aviation , Captain you have taught me a lot thank you
Hi Joe,
I'm a follower from Taiwan.
Can you do a video about how you pay for your flight school which you mentioned at you video 4 months ago on "10 reasons not to become a pilot."
Love to watch your videos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Turbo props have de-icing boots on the leading edge of the wings and even on the vertical stabilizer and horizontal stabilizers because the turbo props are much slower than jet liners plus they fly at a lower altitudes where the ice can occur instantly and this can have a fatal effect on the tail plane. The jets on the other hand fly quickly through the weather and cruise above it so for this reason they dont suffer from same continuous exposure to ice and therefore they don't need any heating systems in the tail plane.
And I really enjoy your videos capt. :)
Nice I have a question what if the ice is accumulated in the fuel tank how do you deal with it please answer the question.
Fantastic question, worth a video!
Heated fuel filters
Yep great question!
Hey Captain Joe, may I suggest that you refer to the air crash investigation episode of British Airways 38 when you do get round to making this video. Very nicely detailed documentary.
There were another ATR fatal crash a month ago in Iran. It crashed during approach phase while weather was freezing and snowy. Airplane was built in 1992 and had not received de-icing system upgrade which is presumably the cause, though inspection is going on.
What fool gave this a thumbs down 👎🏻 ??? This video was awesome ! Like if you agree thumbs up 👍🏻 👍🏻
Thanks buddy!
Captain Joe No problem Joe great channel
Gixer750pilot
Now it's 23 thumbs down i wish i could find these people and ask them why they give thumbs down. I think most are just jealous, there is people out there that can't stand successful people because their life didn't work out for them so they will do anything to see others fail and some thumbs down might just be a mistake. But most of thumbs down are probably by some 50 year old loser still living in his mothers basement and can't stand Joe's success.
Airbus manufacturers
It just goes to show, you can't fix stupid. Here's crossing fingers for an eventual cure.
Im pretty sure the reasons why turboprops are fitted with deicing boots are; turboprops usually have reversible, directly linked, controls. they are more prone to tailplane stalls and ice accumulation, ice build up tends to cause the elevators to move down due to the airflow. Also, they fly slower and the elevator trim is on the elevator itself, unlike airliners where the trim is moving the entire horizontal stabilizer.
Joe, are you going to work in another airline now, and if you are, do you know in which airline you may work?
It'snotaplane 32 He said in the Air Berlin tribute video he won’t tell anyone in comments. He’ll do a video at a later date to reveal
He will work for Eurowings
Video about my pilot career coming up soon!
yayy, how soon tho?
Captain Joe I just can't wait to watch it , such an inspiration
I've flown a Dornier 228. The horizontal stabilizer and fin in case of ice tend to loose effectiveness and the ice build tends to be more fatal due to the shorter arm between the center of the airplane and the tail therefore it has to be protected. The tail on the do228 was made of fabric like the wings on a cub but they all had rubber boots
do air plane have horn
Yes they do!
Just to add a bit to that, it's for alerting the ground crew.
Captain Joe take plane many time never hear it
janis banis Or maybe if the plane infront holding on some taxiway crossing sleeps and doesnt get going? xD
Captain Joe Learn something new everyday! I had no idea woah
Airplanes, have so intelligent systems! Another thing I love.
You are my inspiration sir!! Also was wondering what is your real name?? Except "Caption Joe" ofcourse
I don't wanna post his real name here, but you can find it on the internet with some googling.
Joe :)
You can see it in his video on the logbooks.
Man planes are so complex yet we take them for granted despite being engineering marvels it’s also great that we have the internet to be able to share this info
Hey joe do a video about your new air line please 😻😻😻😻😻😻😻
I like the "DO" a video comments, I´ll see what I can do!
Captain Joe
Thank you so much !!!!!
Lovely.
Absolutely crisp and clear.
Love your vids
Thanks!
Joe, I enjoy your videos. This one was like watching a systems CBT, except you are not boring or dreary! Actually I wanted to add that my jet (MD-80) does have de-ice system on the leading edge of horizontal stabilizer. We activate it every 20 minutes, after exiting icing condition, or 1 minute prior to extending tail flaps. It runs for 2 1/2 minutes, and the wings do not get heated while tail de-ice is operating. I imagine all DC-9 variants have that system. While no one is sure why we have that system, my educated guess is due to unique design of DC-9 flight controls. Our elevators are not hydraulic. They are flown by aerodynamic tabs. When I move the yoke, it only moves the tab. In turn, the aerodynamic momentum flies elevators just like the trim tab does on a 172. Because of it, we are susceptible to tail icing phenomenon. I think the tail de-ice is supposed to prevent loss of controllability due to tail icing.
0:15 I love this plane.
Visit a proper psychiatrist.

So much information! Thank you from Zakarpattia, Ukraine! Even with this cool accent I understood almost whole speech. Greetings and good luck in the air 🙂
Interessant und gut gemacht. Aber ehrlich ich glaube nicht das das E - Deicing System auch nur ein Gramm Treibstoff spart, ersten brauchts ne ganze Menge Strom, zusätzlichen oder größeren Generator , und ein Generator bremst die Leistung der Motoren ganz erheblich , es wäre mal interessant wie das System von BOING aussieht, aber wie immer kommen nur große Worte und am lautesten Trommeln damit es auch jeder glaubt, wie bei einer bek. E -Automarke auch nichts dahinter.
1. Bei dem Air Bleed System fehlt die Luft die zum Enteisen genutzt wird dem Antrieb. (Abgezweigte Luft reduziert ebenfalls die Leistung)
2. In dieser Luft steckt viel mehr Energie drin als benötigt wird, sie muss ja auch erst auf verträgliche Temperatur runtergekühlt werden.
3. Es kann nicht ganze Temperatur der Luft zum enteisen genutz werden, d.h. es geht einiges an Energie ungenutzt verloren
Bei E-Deiceing fällt das Air Bleed System und damit auch sein Gewicht weg.
Man muss viel weniger Energie aufwenden um den selben Effekt zu erzielen, die Flügelkanten werden ja nur soweit aufgeheizt, das sich kein Eis bildet und dafür müssen sie nicht auf 200°C aufgeheizt werden
Stimmt schon, das Gewicht fallt weg , aber Alu - ist leichter wie Kupfer, Widerstandsdraht braucht ne Menge Energie, Die heiße Luft wird bei dem Airbleed system sowie so schon heruntergekühlt. Zweitens jeder weiß das Diesel,- elektrisch, oder mit Benzin, oder Kerosin elektrisch angetriebene Generatoren um elektrische Antriebe oder Verbraucher anzutreiben im Gesamt Wirkungsgrad schlechter sind als die Direktabnahme , Die Physik lässt sich nicht verändern, auch nicht für Boing. die Flügelkanten müssen so weit aufgeheizt werden das sich kein Eis bilden kann, 35000f bei ca 900km/h Temp von -50 Grad and den Flügelkanten ist einige Grad kälter, also mit 50 Grad plus kannst du die Flügel nicht Eisfrei halten
Es gibt auch Alu-Kabel, die auch schon in der Luftfahrt eingesetzt werden.
Wenn du ein Ei kochst, was hat den besseren Wirkungsgrad, wenn du das Wasser auf 100°C erhitzst oder wenn du erst in einem Kessel das Wasser verdampfst, den Dampf auf 600°C bringst und dann wieder auf 100°C abkühlst?
Bei der Direktabnahme ist der Wirkungsgrad nur dann besser wenn nur soviel Energie bereitgestellt wird wie benötigt wird.
Bei einer Flugzeugturbine wird ja nicht einfach nur ungenutze Abwärme wie beim Auto genutzt.
Alu Kabel sind wesentlich schlechtere Stromleiter um die selbe Wattzahl durch das Kabel zu leiten muss das Kabel wesentlich stärker sein , ca doppelte mm/2 zweiten ich wärme ja nichts auf extra, für das Antiicing, die wärme wird so oder so produziert, Bleedair wird auch benutzt um den Kabinendruck zu erzeugen und gleichzeitig eine angenehme Temperatur in der Kabine zu erzeugen , oder sitzen Sie im Flugzeug, mit Winterjacke ,Bempelmütze und Handschuhen und frieren sich trotzdem den Arsch ab.Also die Bleedair wird so oder so heruntergekühlt , der Trick besteht darin den richtigen Abgriff zu setzen um so wenig wie möglich Energie zu verbrauchen.AluKabel sind die schlechteste Wahl, in Hausinstallationen sind sie verboten , die Oxidation des Aluminiums verschlechtert den Widerstand an den Kontaktstellen ganz erheblich, durchgebrannte Kabel oder Kurzschlüsse wären nur eine Frage der Zeit , ich glaube nicht das man die in Flugzeugen verwendet oder verwenden darf, Sie altern auch viel schneller. Sollte Boing solche Kabel verbaut haben , gebe ich Ihnen den guten Rat nicht in eine Boing zu steigen. Aber wie es so ist man kann diskutieren wie man will, ich weis nicht was Boing benutzt und wie das System im Detail aussieht. Für mich sieht es so aus das die Verbrauchswerte schön gerechnet sind um Vorteile beim Verkauf zu haben, solche Rechnungen hat man in allen Bereichen auf dem Papier sieht es gut aus in der Praxis ist es dann ganz anders, da ist halt der Pilot, oder das Wetter daran Schuld wenn der Flieger plötzlich mehr Treibstoff braucht als auf dem Papier vorgerechnet, es wird nur das Optimum angenommen ,nachher kann das sowieso keiner 100% ig nachprüfen weil die realen Flugdaten erheblich abweichen . Wi auch immer , ich wünsche ein schönes Wochenende .
Das Bleedair für Kabinenheizung fällt ja auch weg.
Auch mit größerem Querschnitt sind Alukabel immernoch 40% leichter.
Und es gibt extra für Alukabel entsprechende Anschlussstücke, luftdicht und mit Kontaktfett das Korund enthält um oxidation zu vermeiden.
Im A380 werden Alukabel verwendet
I'm an aviation meteorologist, and I understood that the anti-icing boots on the horizontal stabilizers were because of the smaller radius diameter of the tail plane when compared to the main wings. Smaller radius objects get a disproportionately larger buildup of ice on them. So if ice is building up on all the wings, the (relatively) larger buildup on the horizontal stabilizer will lead to tail plane stalling before the main plane does, thus (in most cases), pitching the aircraft nose-down into a dive. This happened in a Convair crash in New Zealand resulting in the aircraft breaking up in flight (due to exceeding VNE) and the loss of life of the pilot and co-pilot
Can you make a video about 9/11 make a whole story/video I can’t find a true story.
NO! Sorry not my story!
Nick _TV Wtf. Airline Pilot =! All knowledge about every event that ever happened with at least one plane involved
Because in Europe, 9/11 means the 9th of November; nothing special about that day.
6:57 Airbus management, "That is uncalled for, Caption Joe!"
This is very well explained. I think ill become a pilot by just playing FSX and watching and understanding JOE.
Bridging is not a problem for Propeller Planes now. Rubber Tubes inflate and deflate rapidly and prevent Ice Bridging. Old Propeller Planes had Ice Tube that used to inflate and deflate slowly and this used to cause Ice Bridging.
So new planes do not have to wait for ice build up. they can activate ice boots at first appearance.(Boots inflate and deflate rapidly removing ice)
Captain Joe, you are really helping me as an ATPL student in this kind of videos! It’s the best way to understand the theory !!
Big Thank YOU
Wow! This video is way better than those manuals and textbooks.
I’m not a pilot and never will but enjoy your knowledge and all your Videos thanks
I think because, in small airplanes like turboprops, the controllability is a lower and with the "cooling plus", is more lower. the icing-boots prevent the build of ice in.
Thanks for the video! I just watched it because I didn't understand why the inboard part of the wings leading edge isn't heated. Gave me some good information for my aircraft subsystems university exam next week.
I believe that the waiting time for deice Boots activation is nowadays a myth. It mostly applied to older boot systems. Modern deicing boots are deployed at very high speed thus preventing bridging effect and in manuals it is requested for pilots to activate the system immediately after visible accumulation of ice and not calculating waiting time.
I'd apply the deicing systems frequently to prevent icing. Liquid deicing is another efficient way for small plaes. Elevator icing won't be a big issue unless the control systems got hard over.
Carbureted planes can get their carburetors frozen, restricting the fuel flow, and eventually causing an angina failur. Below 2,000 RPM, in IMC or in icy conditions, we have a lever next to the thrust lever we pull out to electrically heat the walls of the carburetor. While its on however, engine rpm drops drops a little bit due to the increased temperature
As an aircraft enthusiast and jet engine design engineer, I really like ur videos. I hope we can meet someday and talk about airplane. Ur big funs
Joe don't forget the fabulous 50s! The DC-6, DC-7 and C-123s used a combustion heater inside the wing to generate hot air for the wing leading edges. That's right! there was a souce of fire inside the wing surrounded by all that fuel. I bet this was checked VERY carefully in pre-flight.
Thank you Captain Joe. Your presentation and speaking style are impeccable! I find it useful to consider your style when I have to present something and I don't even work in the aerospace industry.
Fascinating and educational as always. Another great video. Keep up the amazing work
Thanks Steve, appreciate it :)
Thank you!!!
The BEST video yet!
Please make more on systems!
Sincerely,
AMT student.
Pressurisation systems, air-conditioning,
Fire & extinguishers
Etc.
Some of the melted ice is directed to the aft cargo door ice water inlet valve doodad where there is a water cooler. The water is then recooled via vortex generators and the resulting ice is used as cubes for the mixed drinks for the pilots, crew, and happy passengers.
Thanks ! Capt. Joe... your videos really helps to clear all the doubts regarding any system.
I would love to see a video explaining how trim control works, why you not use it or why not to often and why it does 180/360 turn when there is an autopilot etc.
