One fun thing about JetBlue is that they have a name/phrase for every aircraft in their fleet. So next time you do a JetBlue flight, please get the name of the plane to post in your stats listing. You can see it painted on the nose of the plane. If you cannot get that from the terminal window, just ask a flight attendant, they would know. For example, on your plane for this flight it is called "Bahama Blue". Here's a sample of some of their other plane names... Bluebird Shades of Blue Blue Skies Wild Blue Yonder Blue Crew Canard Bleu True Blue Out Of The Blue Royal Blue Blue Moon It Had To Be Blue Blue Velvet Baby Blue Blue Ribbon Born To Blue Blue Belle Cool Blue
Another great video! Interesting -- I believe that the APU may have been inoperative for this flight, because from 2:48 -- 3:50, the sound of an main engine being started at the gate can be heard. Auxiliary Power Unit -- a small jet engine mounted in the tail, furnishes electric power and air conditioning, at the gate, whenever the main engines are shut down, and can also be used inflight for both electric power and pressurization/air conditioning). The APU isn't required for flight and can be inoperative for a few days, since procedures exist to work around an inoperative APU. I wasn't on the A320; I flew the B737, but the only time we started an engine at the gate was when the APU was placarded as inoperative by maintenance . It was necessary to start one engine at the gate because a GPU (Ground Power Unit) cable was connected to the aircraft to provide electric power and a high-pressure air cart was connected to the aircraft to provide the air pressure necessary to turn the air-driven engine starter. After one engine was started, ramp personnel would disconnect both the Ground Power Unit and the High-Pressure Air hose, before push-back off the gate commenced. At 14:20, the sound of the second engine being started can be heard. If the APU is indeed inop, the running engine's thrust would need to be increased to provide the air pressure necessary to start the second engine. The crew would only do this away from the gate area, to avoid blast damage caused by the increased thrust on the operating engine. Since they were taxiing uphill to Runway 27L for departure, this would not have been a big issue, since more thrust would be necessary to go up the inclined taxiway. Around 15:37, audibly, the second engine has stabilized. The "barking" sound quit, as soon as the sound of the second engine is being started began -- I believe that they might be related -- maybe due to the single-engine taxi procedures that our employers want us to use, to save fuel.
You would be correct. We had an air start on this flight. The APU was indeed, inoperable. Trying to start the engines cold, without an APU or air start, is very bad for the engines and is called a hot start. A large amount of air is needed to move though the engines to start them properly and once the air start is used for the first, it'd be disconnected and bleed air form the first engine would be used to start the second. All of which you went through in your post, I just thought I'd elaborate slightly more on some of it. Thanks for watching my friend!
@@sla31 You're welcome -- great videos, BTW! One little point, though. Starting the engines with an high-pressure air cart and GPU doesn't actually produce a hot start, unless the high-pressure cart isn't functioning properly. That would be a cart that is not providing a high enough air pressure to get the engine up to 25% rotation speed, before fuel & ignition are added. In my experience, a well-maintained air cart could readily start the engine, most times with a lower peak EGT, than could be achieved with the APU -- especially a weaker one. Cold engines usually start with a lower peak EGT, than warm ones. An actual hot start is usually caused by the addition of fuel (by raising the engine start lever to the idle detent), before the engine is turning fast enough to accelerate up to idle before the EGT gets out of hand.
@4KFullFlight Does the flight sim aircraft have an APU? If not, and also if you want to have a more accurate flight sim experience, you might want to try just starting the left-engine at the gate. After airstart cart and GPU disconnect, push back off the gate. While taxiing out on a taxiway, increase the operating (left) engine until you see 30 psi on the overhead air conditioning panel (both packs are off), then start the right engine, while still taxiing. That's how it's done in the real world -- albeit, the captain would taxi, while the FO would start the second engine. If you're not comfortable with taxiing and starting, you could pull over into the runup area to start #2. 🙂
@@boeingpilot7002 I think you misunderstood what I was trying to say. You're correct, that an air cart wouldn't produce a hot start. What I was saying was that starting the engines without an air cart would create a hot start. I.e., the APU is broken and attempting to start the engine without the help of the air cart. We're saying the same thing. That the cart is used to prevent such a thing from happening.
@@sla31 Oh, ok -- now I understand. The only thing is that the starter-motors on these engines operate using high-pressure air; not electricity. Thus, without either an APU or a High-pressure air cart, an engine start would not be possible. The only function of electricity is to excite the ignitors during the start and to open the engine-mounted fuel valve to allow fuel to be introduced during the start process. Thus, a hot-start without a high-pressure air source would not be possible.
Dont we all love the a321?Such an amazing plane one of my favs for sure!!It has beautiful CFM 56s with the options of IAE 100s it such a beautiful plane
Noticed that the double-blinking wing strobe lights did not come on until the aircraft was in the air. Always thought the wing strobes were supposed to be on whenever the aircraft was on the runway (maybe I'm wrong).....love the double-blinkers on Airbus aircraft.
The wing strobes are supposed to be on any time you're on a runway. Even if you're just crossing a runway. In this situation, if the aircraft were older aircraft, it could've been a frame rate issue. Where the camera wasn't synced up with the brief moment the flash happened. But now, with LED lights, that's not an issue anymore. It always catches them. Especially at 60fps. I think this is more likely the pilots forgot until you see them come. We all like to think pilots are perfect. Checklists, simulation, the endless training they go through, etc. But, in the end, they're all human too and this was an early flight haha. This wouldn't be the first flight I've been on where the strobes came on later than they should've haha. I'd bet it was missed in the checklist.
It could also be that JetBlue policy is to run them on the auto setting which wouldn’t activate them until there in no longer weight on the wheels. But I am justt speculating and not an actual pilot.
@@sla31 I am not an expert but I think on Airbus aircraft the strobes have an auto feature where they switch on immediately as the aircraft wheels are off the ground and turn off right after the main gear touches down, I could be wrong though. Nvm, after watching the takeoff, the strobes did not switch on automatically, therefore I am assuming they forgot to manually switch them on. But, the crew eventually caught on lol.
what a beautiful aircraft. it seemed they may have had aNn INOP APU and started #1 engine at the gate? the odd thing was then the single engine taxi without using the yellow electric pump hence the PTU running constanty which truly made my dog growl at the computer..LOL.. Great video SLP
That A321-231 looks about the same size as the old 707 yet it's being powered by those two relatively small looking engines. Hard to imagine how they get so much power out of them. And without them exploding, lol.
This has to be one of my favorite uploads. Thank you. I love nighttime flights, and I should take more of them because they look so relaxing. As you know, I have a fear of turbulence. Has your experience been that night/red-eye flights are less turbulent than morning or afternoon flights?
Morning flights are usually the best, in my experience. The afternoon is of course when the sun has had maximum time to cause disturbances by evaporating water, changing the temperature, etc. And in my time flying, some of my most turbulent flights have been over the Pacific at night. Some of it's just luck though.
Yeah, I'd like to do that. The timing of the flight is the issue. I believe it's usually an overnight flight. That would be almost all in the dark. It'd be the reverse (LHR-JFK) that I'd be more interested in. When you do the full flight, like me, completely dark flights are kind of.... Well, there's not much to watch haha.
Ok, me again! I'm so sorry to be bombarding your channel with questions (thank you so much for taking the time to answer. I'm not always the best at typing in my questions coherently enough for Google when it comes to this sort of thing - we really need a "hey Google what's this sound?" function!), but can you by chance tell me what the noise is that begins around 12:08? I've always thought it was mechanics doing final checks and getting things situated, but this noise continued while the plane was moving, which I haven't seen before.
It’s no problem my friend. As I said before, I’m always more than happy to answer questions. So what you’re hearing at 12:08 is basically the aircraft’s hydraulic system. Specifically, it’s a pump called the power transfer unit or (PTU). So, aircraft all have redundant systems to ensure they can continue to operate if one system goes down, and that includes separate hydraulic systems. These systems are usually operated independently by each engine. So when only one engine is running, there needs to be a bridge to send power to both systems, and on Airbus A320 series aircraft (like seen here) that job is completed by the PTU. So at 12:08 here, the first engine had been started, but the second engine wasn’t running yet, so the PTU kicks in to make sure all of the hydraulic systems are getting power. The reason it then disappears is because the second engine has been started and it is now powering the the other system. If an engine were to fail for whatever reason, the PTU would once again spring to life, pulling power from the other engine to keep all the hydraulic systems active. All aircraft have a system like this, but it’s just very loud on A320 series aircraft. In fact, the A320 PTU is often the joke of “weird airplane noise” jokes. All normal, and actually a very cool safety system. Fun side fact. If for some astronomically insane reason both engines are lost, there is another, even cooler safety feature that planes have. It’s called a ram air turbine, and is a small propeller that deployed under the aircraft, that when spinning provides enough power to the PTU and systems of the aircraft so that the pilots can still control everything, even with no main power. Aviation and the safety measures that go into it is truly remarkable 😊.
These night flights are getting better and better! I might hop on a red-eye next month, is there any advice for filming clearer sunset/night footage with an iPhone? In the past issues like the reflection or the video being simply too dark, etc, have always been a drawback.
Reflection is always going to an issue and there’s not much we can do about it. That’s up to the flight attendants haha. As for filming darkness or darkness to dawn or dusk to darkness. That’s tough…. That’s the hardest to film and there’s really no way to do it efficiently without potential messing up the iPhones focus.
Well, I post three brand new full flights every week, and I have over 800 of them posted now. So, that's quite a lot for you to browse haha. Thanks for watching my friend!
I'm flying the jetblue plane on June from ATL to BOS! And I'm honestly really scared I've never took a plane since I was 2 and now I'm 13 so I lost track of some of the experience but I'm trusting in jetblue to take me there safely tho!!
Engine 2 started while on the gate suggesting an APU failure. At takeoff pilot forgot to turn on the strobes...only past 2000 ft he was like "s..t" forgot them! I like your videos tho!👍
You'd be correct on both accounts haha. Well definitely on the first, we did indeed have an inoperative APU. As for the strobes, that does seem like the most likely option.
@@sla31 yes. Strobe light are mandatory right before the plane hits the runway, even when it is just crossing it during taxi. Sometimes pilot forget to turn them on...especially at early morning😉
@@alessiozavaglia3455 Yes, I'm aware of the rules, I was simply saying that you inferring that it was likely forgotten was likely correct. In fact, I even left a comment on another thread that said they likely forgot them because it was an early morning flight and pilots are human after all haha.
Amazing video! Great quality and sounds. May I ask, how do you hold the phone - Do you have a suction cup of sort to hold your iPhone? (If you do, may I have the link to it please :)) Thank you for uploading :)
Thanks my friend! Glad you enjoyed it. I hold the camera by hand. There is not mount that I’ve been able to find that works with an iPhone and will keep the vibrations from getting into the lens of the camera.
I don't know why they never did. Except that Southwest has always been very high on having as few fleet types as possible. I know they're all 737's, but it was a very long time into their history before they even ordered the 737-800. I don't know that I'd rule out them getting the Max 9, but I haven't even heard rumors they're interested in the 9.
@@sla31 Oh okay cool. Because I mean, There really isn't any difference in terms of flying among the different 737 variants? Correct me if I am wrong I am not an expert in anyway but I guess since I know some of their flights could get crowded, maybe adding the MAX 9 or 10 might be a good idea, and it is still sticking with fleet commonality to reduce costs. Thanks for the reply.
@@JungleJetAviation06 I'm not 100% sure on this, but I think there is a difference in the NG vs. the Max. I believe the pilots have to be trained on them separately. I don't know about the 7, 8, 9, or 10 Max though. I don't if one type rating covers them all or not.
What you saw there was some very minor turbulence. You probably wouldn't have even really felt it. I'm sure other people have told you similar, but I'll tell you as well for the reassurance. Turbulence is normal. You're never going to have a completely smooth flight from start to finish. But, there's absolutely nothing to worry about. The aircraft are built to handle it. In fact, they're designed, built, and tested to withstand magnitudes of turbulence and abuse that you will absolutely never encounter in the real world. They literally put aircraft wings in a machine that bends them. And in those test they apply loads to the airframe to replicate 150% of the most extreme forces the airplane is ever expected to experience in service. And they all must pass these tests before the aircraft type can be certified by the FAA. So, there may be bumps along your flight, but the aircraft are very strong and built to handle it. The crew and pilots are also trained to handle it, and they do every day. So, I know telling you not to worry doesn't help, but hopefully telling you that with some of the above information does help.
Am I going crazy or did the pilots forget to turn on the strobe lights for takeoff? Awesome flight! Glad that the PC is fixed and we are back to new content!
Yeah, in the past, before LEDs it could’ve been a camera frame rate issue. Where it was just missing it. But now days, at 60fps and LED lights, the camera doesn’t miss it. Seems they forgot.
Well, I do love them all. But I'd say I get the most excited about the types I don't get to fly on much. The A380, 747, A340 come to mind. I've flown on all of them. Most of them recently even, but they're still few and far between now.
That would be form my cameras that I take with me on all the flights I take haha. Everything you see on here, I film myself. I am a one man show here and I don't have other people funneling footage to me, just to post. I've taken 180 flights so far this year.
It comes on a few minutes after takeoff. Several others have been discussing this in the comments. We believe the pilots just forgot to turn them on until you see them come on.
Yes, but not unheard of. And sometimes, like on this flight, it's required. So, this aircraft's APU was inoperable. The APU is a small jet-engine in the tail used to provide power to the plane when at the gate, and it's also used to start the two main engines. Turbine engines require a large amount of airflow to stay cool when starting. If they do not have a large amount of air flow, they'll perform what's called a hot start. That means they would exceed their recommended safe temperatures because they didn't have enough air. The APU provides the air needed for this. When the APU is inoperable, the first engine needs to be started with help from what's called an air start. It can also be called an air cart. It is a machine designed specifically to force air through the aircraft's engine, in place of an APU. But, the plane can't move while it's attached, so the first engine has to be started at the gate. Once the engine is started, the air start is removed and the plane is pushed back. The running engine can then use bleed air to start the second engine.
That is the famous Airbus A320 series PTU (power transfer unit). When only one of the two engines are running, the PTU is used to transfer power between the various hydraulic systems. Once the second engine is started it is no longer needed. Hence why it disappears.
That is the aircraft's power transfer unit, or PTU for short. It's basically a pump that helps keep pressure in all of the aircraft's heraldic systems until both engines are running. All aircraft have something similar, it's just really loud on Airbus aircraft if you're seated over the wing.
Yes. I’m not sure if it’s “required” by the FAA or if the airlines just do it on their own. But you can usually find the aircrafts “country of origin” in the safety card. Where it was assembled. For A321’s that’s France, Germany, or now the US.
@@marcuskeulertz5852 Yes, true. But I'm pretty sure the flag on these safety cards is in referring tot he aircraft's final assembly place. On other airlines the cards specifically say "final assembly of this aircraft completed in Germany." And A321's are only assembled in France, Germany, The Untied States, and China. Although the Chinese plant only builds them for Asian customers.
This one's for all of you who always ask for more JetBlue! Here's some JetBlue! Enjoy 😁!

These night flights are getting better and better! I might hop on a red-eye next month, is there any advice for filming clearer sunset/night footage with an iPhone? In the past issues like the reflection or the video being simply too dark, etc, have always been a drawback.
Reflection is always going to an issue and there’s not much we can do about it. That’s up to the flight attendants haha. As for filming darkness or darkness to dawn or dusk to darkness. That’s tough…. That’s the hardest to film and there’s really no way to do it efficiently without potential messing up the iPhones focus.
This may sound totally crazy, but I think these newer iPhones should have nvcs (night vision cameras). @@sla31
First I guess? Was that the hydraulics going during the outbound taxi?
That is the PTU or Power Transfer Unit that makes the barking noise.
Yes, as AviatorTrav said. Specifically what you're hearing is the PTU, which is part of the hydraulic system. Thanks for watching!
Great fly! I don't know if you ever heard Linux but have you used Linux, an alternative operation system to MacOS and Windows?
Heard of it, yes. Used it, no.
I’ve been in a go around into Boston ma
I love full flights I want more full flights
Well, I post three brand new full flights every week, and I have over 800 of them posted now. So, that's quite a lot for you to browse haha. Thanks for watching my friend!
I'm flying the jetblue plane on June from ATL to BOS! And I'm honestly really scared I've never took a plane since I was 2 and now I'm 13 so I lost track of some of the experience but I'm trusting in jetblue to take me there safely tho!!
You'll be fine my friend. You'll probably even enjoy it. JetBlue is a safe airline, and all of their crews go through tons of training.
Engine 2 started while on the gate suggesting an APU failure.
At takeoff pilot forgot to turn on the strobes...only past 2000 ft he was like "s..t" forgot them!
I like your videos tho!👍
You'd be correct on both accounts haha. Well definitely on the first, we did indeed have an inoperative APU. As for the strobes, that does seem like the most likely option.
@@sla31 yes. Strobe light are mandatory right before the plane hits the runway, even when it is just crossing it during taxi. Sometimes pilot forget to turn them on...especially at early morning😉
@@alessiozavaglia3455 Yes, I'm aware of the rules, I was simply saying that you inferring that it was likely forgotten was likely correct. In fact, I even left a comment on another thread that said they likely forgot them because it was an early morning flight and pilots are human after all haha.
@@sla31 by the way I subscribed to your channel.
Keep up with the good work my friend!
@@alessiozavaglia3455 Thanks my friend! I appreciate that!
Great job👍✈️
Thanks for watching my friend!
You flew through a turbulent areas over the atlantic towards Boston.
Amazing video! Great quality and sounds. May I ask, how do you hold the phone - Do you have a suction cup of sort to hold your iPhone? (If you do, may I have the link to it please :))
Thank you for uploading :)
Thanks my friend! Glad you enjoyed it. I hold the camera by hand. There is not mount that I’ve been able to find that works with an iPhone and will keep the vibrations from getting into the lens of the camera.
Nice vid as always! Question, do you know why Southwest never acquired the 737-900? And do you think they would add the MAX 9 or 10? Thanks.
I don't know why they never did. Except that Southwest has always been very high on having as few fleet types as possible. I know they're all 737's, but it was a very long time into their history before they even ordered the 737-800. I don't know that I'd rule out them getting the Max 9, but I haven't even heard rumors they're interested in the 9.
@@sla31 Oh okay cool. Because I mean, There really isn't any difference in terms of flying among the different 737 variants? Correct me if I am wrong I am not an expert in anyway but I guess since I know some of their flights could get crowded, maybe adding the MAX 9 or 10 might be a good idea, and it is still sticking with fleet commonality to reduce costs. Thanks for the reply.
@@JungleJetAviation06 I'm not 100% sure on this, but I think there is a difference in the NG vs. the Max. I believe the pilots have to be trained on them separately. I don't know about the 7, 8, 9, or 10 Max though. I don't if one type rating covers them all or not.
When the wing is bouncing a bit at 48:00 is that turbulence? I fly on Friday and I'm terrified.
What you saw there was some very minor turbulence. You probably wouldn't have even really felt it. I'm sure other people have told you similar, but I'll tell you as well for the reassurance. Turbulence is normal. You're never going to have a completely smooth flight from start to finish. But, there's absolutely nothing to worry about. The aircraft are built to handle it. In fact, they're designed, built, and tested to withstand magnitudes of turbulence and abuse that you will absolutely never encounter in the real world. They literally put aircraft wings in a machine that bends them. And in those test they apply loads to the airframe to replicate 150% of the most extreme forces the airplane is ever expected to experience in service. And they all must pass these tests before the aircraft type can be certified by the FAA. So, there may be bumps along your flight, but the aircraft are very strong and built to handle it. The crew and pilots are also trained to handle it, and they do every day. So, I know telling you not to worry doesn't help, but hopefully telling you that with some of the above information does help.
@@sla31 Thank you
Awesome!
Thanks my friend!
I had a similar JetBlue flight like this on October 5 2022 from PBI to JFK
Nice video 👍
Glad you enjoyed it my friend!
Does JetBlue offer flights from the east coast or Florida to Salt Lake City and Albuquerque??
JetBlue flies to ABQ from New York's JFK airport. They then fly to SLC from BOS, FLL, LAX, JFK, and MCO.
@@sla31 Thanks a lot for the info. Hopefully they will serve MIA soon.
Am I going crazy or did the pilots forget to turn on the strobe lights for takeoff? Awesome flight! Glad that the PC is fixed and we are back to new content!
They definitely forgot! It seems strange because it is usually a standard part of the before-takeoff checklist!!! Great flight video!
Yeah, in the past, before LEDs it could’ve been a camera frame rate issue. Where it was just missing it. But now days, at 60fps and LED lights, the camera doesn’t miss it. Seems they forgot.
They definitely were like “shit we forgot something” bc they turned them on shortly after lol
it was probably on mode AUTO, where it turns on immediately after takeoff for this very reason@@al380aviation
What jet do you get most excited to fly on, or do you just love them all?
Well, I do love them all. But I'd say I get the most excited about the types I don't get to fly on much. The A380, 747, A340 come to mind. I've flown on all of them. Most of them recently even, but they're still few and far between now.
@@sla31 The DC-10 was my favourite,because it is a fast steep take-off straight up like a rocket.,that got my vote!.
I'll be ready
Where do you get all of these plane videos from?
That would be form my cameras that I take with me on all the flights I take haha. Everything you see on here, I film myself. I am a one man show here and I don't have other people funneling footage to me, just to post. I've taken 180 flights so far this year.
@@sla31 How do you afford to fly everywhere?
1,000,000 views per month on UA-cam haha. That’s how 😂.
@@sla31 Asome!!!👍👍👍
I’m shaken never thought this would happen lol
12:05 - dog barking!)))))))
😂😂😅😅
It's cool!
Love it :)
I'm glad you enjoyed it my friend!
why isnt the strobe on??
on takeoff
It comes on a few minutes after takeoff. Several others have been discussing this in the comments. We believe the pilots just forgot to turn them on until you see them come on.
Jeez, I usually like the PTU noise, but it was kind of irritating on this flight lol. Just non-stop during taxi for a good minute or two
Did they forget to turn on the Nav lights? Appear to only start flashing a couple of minutes after take off...
Yes, they did 😂.
Gotta love noisy flaps! (Said by nobody ever🤣)
no one with box cutters right 😆 🤣 jokes
Aw it’s the baby and dad Bahama Blue aircraft’s A321 and 20
❤❤❤❤ I love ✈️ errr isn’t unusual for a airplane to start there engines while at the gate?
Yes, but not unheard of. And sometimes, like on this flight, it's required. So, this aircraft's APU was inoperable. The APU is a small jet-engine in the tail used to provide power to the plane when at the gate, and it's also used to start the two main engines. Turbine engines require a large amount of airflow to stay cool when starting. If they do not have a large amount of air flow, they'll perform what's called a hot start. That means they would exceed their recommended safe temperatures because they didn't have enough air. The APU provides the air needed for this. When the APU is inoperable, the first engine needs to be started with help from what's called an air start. It can also be called an air cart. It is a machine designed specifically to force air through the aircraft's engine, in place of an APU. But, the plane can't move while it's attached, so the first engine has to be started at the gate. Once the engine is started, the air start is removed and the plane is pushed back. The running engine can then use bleed air to start the second engine.
4:00 Gesundheit !
12:21 what is this noise?
That is the famous Airbus A320 series PTU (power transfer unit). When only one of the two engines are running, the PTU is used to transfer power between the various hydraulic systems. Once the second engine is started it is no longer needed. Hence why it disappears.
Did you notice the captain or the first officer didn't turn on his strobe lights until about a minute after takeoff.
Yeah. We've been discussing it throughout several other comments. It would appear they just forgot to turn them on. Thanks for watching my friend!
Where do you actually live FL?
Nope, I live near Joplin, Missouri.
JetBlue Airways is always cheap for this time of the year best airline.
13-01 - what is the sound??
That is the aircraft's power transfer unit, or PTU for short. It's basically a pump that helps keep pressure in all of the aircraft's heraldic systems until both engines are running. All aircraft have something similar, it's just really loud on Airbus aircraft if you're seated over the wing.
@@sla31 Thanks!
❤❤❤
I detected the german flag as a dot on the flight security Sheet.
Yes. I’m not sure if it’s “required” by the FAA or if the airlines just do it on their own. But you can usually find the aircrafts “country of origin” in the safety card. Where it was assembled. For A321’s that’s France, Germany, or now the US.
@@sla31 Airbus has another factory in Getafe near Madrid,Spain,where they built the ailerons.
@@marcuskeulertz5852 Yes, true. But I'm pretty sure the flag on these safety cards is in referring tot he aircraft's final assembly place. On other airlines the cards specifically say "final assembly of this aircraft completed in Germany." And A321's are only assembled in France, Germany, The Untied States, and China. Although the Chinese plant only builds them for Asian customers.
That was a long ptu 😂🤣🤣
Qatar next
