It's also a ferocious sounding plane. That prop tone you hear at 2:10 is often the loudest sound at the airport if it isn't a military base. I call King Airs the Dodge Hellcats of General Aviation. Because they sound mean as can be, they sound powerful, and they are a joy to listen to. (Even a bit humbling when you're right up next to one while its running) Even if you need hearing protection within 700 feet of them 😅
As someone that’s worked on these things & hates them with a burning passion I just wanna say that I appreciate people like you who love them. They do look good though. 😂
Either thats a brand new aircraft, or someone has been taking very very good care of the control panels. Not a scratch on them, they all look brand spanking new
Brilliant video, simple to understand, amazing to see the feathering mechanics at work and whilst for many this might seem banal, I found it fascinating.. Well done lad for a super piece of footage and delivery.
I don't fly so this means nothing to me but it came up in my feed so YT felt I needed to see this. Was not disappointed. My inner geek has been satisfied.
Reading about this in theory makes me scratch my head wondering what the heck are they talking about. Thanks to your video I can finally visualize it properly.
This guy is a legend. He says Governor like a proper champ, and he sets the prop rpms to 420 in the video and doesn't even make a joke about it, but pauses a bit when saying it and hurries over it.
This is one of the best videos that explains and shows how the props change pitch and I too love that turbine sound. The KingAir is a beautiful aircraft.
0:55 I love that sound when a king air starts! I've gotten to work on some king airs in the hangar I work at, while they're a little difficult as far as their engineering goes, they are a joy to look at, and a joy to be around. King Air is easily one of the best planes ever built.
Thanks, believe it or not I've always wondered what the change in engine noise was on start-up. Now I know it's the revs changing as the governor takes over.
Interesting! I used to fly my multiengine schoolflights at c90. Nice plane and plenty of power. You have even glass cocpit! We had steam gauges all over 😄
I remember on the 99's every winter rigging the reverse torque and every spring rigging them back. This was in northern Ontario where winter daytime temperatures could be below -30c.
Fine: pushes little air per revolution, results in higher RPM and less torque, keeping power reserves for go-around etc. Coarse: pushes more air per revolution, lower RPM, higher torque. Too much torque will damage the engine. Feather: pushes little to no air, reduces drag and allows for better glide performance in case of engine failure
@@matthiaspatzelt3085 wait, i thought coarse is feather in props ?! because the angle of blades in feathering and in coarse results in little to no RPM
@@Mode_Sierra I'm a true fan! loved helis since age 3. This is the first video I've found that answers all my questions in full, i'll be sure to check out your others ;)
Wouldn't it be fascinating to be able to see through the whole of the engine as if it were glass and be able to observe all of the internal workings. CGI animations can provide this but they're not the "real deal", maybe in the future a material will be designed that would allow this.
Very interesting indeed ! Thanks for this demonstration. I am not used to turboprops, flying only small piston engines. What about the fuel consumption during feathering ? Does it increase because of the higher resistance of the prop ?
It’s neglible. Remember that the engine is never working any harder throughout the process. The “Power Levers” are never touched during the demonstration… it’s idle power throughout.
Does the red morse cable on the port engine shown.. have too much kink behind the casing mount.. causing a cable core fray to failure point.. ???????? it might be interesting to cut the ends off a used cable and extract the cable core to check for hard spots from excessive flexing. then unwind the core strand by strand. in that area..
Thank you for showing the prop mechanism, never actually saw it in action during eight years of aviation! Gotta love pilots thinking of the community while doing those kind of tests :-) Got a question for you: Why do the boost pumps need to be on during shutdown or a least until N1 being below 10 percent? The condition levers are already in the cutoff position, why worry about boost pumps and N1?
You are welcome! Glad you liked it. Someone else asked the same question, so I’ve copied the answer. Let me know if it explains it ok. The purpose of the electric boost bumps is to prevent cavitation of the engine driven fuel pumps. Cavitation (destructive) happens when there is back pressure in the fuel flow and “bubbles” that vaporise form in the fuel pump. Cavitation can destroy your engine driven fuel pump over time. And no engine driven fuel pump means “bye bye engine”. The electric boost pump operates at a much lower pressure than the engine driven fuel pump and can’t support the required fuel pressure for the engine. It only serves to protect the engine driven pumps from cavitation damage. Above 10% The electric boost pumps still do their “job” of preventing cavitation. Once below 10% the risk of cavitation ceases and the boost pumps can be turned off. Hope that explains it ok.
That was really interesting to watch without engine cover. One question, which may appear really minimal, but when you toggle some switches you use a thumb and forefinger movement as if "pulling" the switch. Is this a mechanism in the switch requiring to pull it out, or is just best practice so you know you've completed it?
That’s a good observation. Yes, your assumption is correct. Some switches on the panel are of the type that requires you to pull the switch before moving it. This is to avoid unintentional or accidental switching.
I agree with Johan, that was a really good observation. I tried to find a diagram of one, but couldn't. Essentially some of the King Air switches have a tooth that you have to pull the spring-loaded sleeve on the switch back over the tooth to shut it off. That is so they aren't inadvertently turned off in flight. If I find a diagram I'll come back and post it.
@@Mode_Sierra I noticed that too. I thought with that panel down by your left hand side you could wreak havoc with just the brush of an arm. Now I know why you don’t. Thanks very much 👍🏻👍🏻

The King Air is just a gorgeous turboprop inside and out. But, really love the cockpit.

Yeah, it’s gorgeous, but the inboard tanks between the engines and fuselage are a pain in the a$$ to get to and fuel!!!
@@goofygolfer56. Not ‘signal point?’
@@Posttrip Nope. One, two or three tanks per wing with the mains being between the engines and fuselage

I was watching and just thinking about how much I love the sound of turbines when you said it for me!
Good illustration of how many systems and controls come into play just to start the engines. Thank you!
Reading about this in theory makes me scratch my head wondering what the heck are they talking about. Thanks to your video I can finally visualize it properly.
I love this video! What a concise explanation of how the prop control works!

You are right, not something you get to see very often. I like that you went through the start up. Good video. Thanks for sharing.

Used to love cranking up the APU on the C-141B. Sweet music to the ears.
King Airs are so sweet. Thanks for the demo, it's fantastic.
Very Nice video! Completely clear, direct and didatic. Great!
Hello from São Luís Maranhão Brazil!
Great demonstration!
Really interesting video. Thanks for taking us thru each step and explaining the reasoning for each.
Although I knew almost nothing about aircraft, this vid is very interesting for me (and others alike)... Thanks for the rare demo. Be safe 🌹
I worked on 350’s and next will be 1900’s. In my opinion, beautiful aircraft.
Nice simple demo and explainations, thank you!
No problem... sometimes simpler is better hey :)
Great video .. never saw propeller pitch change function in action before .. good one
fascinating demonstration! your camera even enables to see the propeller pitch movements!
Thank you for this video!
A very good, educational video.
Great demonstration! Thanks!
I’ll do some more some time
Awesome video!! Thanks for this!
What an awesome video,thanks!

You got it 👍🏻
absolutely love this
What a treat thank you!
Great video!
perfect, thanks for this lesson :-)
Thanks For this vid !
Very cool. Thanks for sharing.
Fascinating! It is interesting how those boost pumps would run, even before the battery master switch was switched on.
Yes, they are on the “hot bus” and one of the C90 “gotcha’s” to look out for. Could drain the battery regardless of battery switch position.
That was very informative and concise, now I'm sure I can fly it! I'm interested in the mechanical linkage that alters the pitch of the propellers.
Hi, if you research “propeller governors” you’ll see how the governor works to maintain propeller RPM using engine oil.
Great video instruction!
Beautiful.
This is super interesting!
Fine: pushes air, lets you fly
Coarse: almost no air resistance, lets you glide
The way I used to remember it is Coarse sounds like Cut, props turn into little knives in the air.
Fine: pushes little air per revolution, results in higher RPM and less torque, keeping power reserves for go-around etc.
Coarse: pushes more air per revolution, lower RPM, higher torque. Too much torque will damage the engine.
Feather: pushes little to no air, reduces drag and allows for better glide performance in case of engine failure
@@matthiaspatzelt3085 thanks, sure its nothing for those who knows but means a lot for those who know nothing like me... 😅👍

You can either buy it part by or buy plane and a business jet have 2 different motor for flight
Quick question, do ones require somekind of key or card to start an aircraft (ie like starting a car engine) before all those starting seq? 🙏
