[David Attenborough voice] The Jetstream 41 uses rapidly changing patterns on its propellers to attract mates, and to ward off any potential predators...
I just saw a vid of an airport employee in Russia walk into a prop that was solid black except for a little bit of yellow on the tips. The prop made a mess of his head and he was instantly unalived.
Love the Jetstream 41 and 32 because of their relative long nose-sections and the cross-tail units. The sound is amazing. Thank's for sharing this with us.
That was totally awesome. Those props are hypnotic and massive! Love the Jetstream aircraft, wish BAe were still building civilian aircraft. Fantastic clip, icing on the cake when the reverse thrust used for push-back 😲.
Props? what props? I didn't see any props. LOL Bear in mind that in a video there's a chopped frame rate that causes that effect. It just looks like a whirling blur with model Mark1 eyeballs.
C130s are GREAT. I remember going to Brightstar 85 in Egypt. We were bringing 4 C130 tac birds from Keesler. Got there in advance of the planes and was told to "clear the FOD" from the parking area which meant sweeping the sand and dust and rocks off what passed for asphalt. I have literally "swept" the desert in Egypt. Butt apparently that wasn't good enough (nor needed) The C130s just stopped in front of their spots and BLEW the dust off their spots.
Type Rated in the '41 with ACA. Great fun. Loved those -14s. Many of those engines are powering S2Ts for CalFire now is the scuttlebutt. Parked ours at Loring AFB in Maine decades ago.
I used to work at Norwich airport and did the cleaning on these for Eastern, I loved the sound of them at startup... Ive been on JY quite a few times usually she was on the Aberdeen-Norwich run
Recently saw a Twin Otter do the same thing over in Canada, via RUclips. Been a while since I've seen turboprops backing themselves out for departure. I was normally used to seeing 737-200's, 727's, DC-9's, and MD-80's doing this kind of maneuver, way back during the early to mid 1990's - jetliners from the late carrier Continental Airlines (now United).
Nice. Perfect demo of the startup procedure for my PMDG. It's different because you can't keep the FMC lit without either the GPU or a generator running. So you can't start during pushback.
Great airplanes. No heavy rudder inputs at takeoff due to counter rotating props, but noisy as hell. EasyFly in Colombia flew this model until 2019. British airplanes designers seemed to like engine noise, notably the Spey, and the Dart. All still ringing in my ears even 30 years later. It explains my ringing ears. Great catch.
It’s not just the engines, it’s British design. The Lycoming O-540 is a fairly quiet and smooth engine in planes like the Aztec and Navajo, but it’s eardrum piercing in the Islander.
That pattern on the prop blades is quite eye catching on the camera! Makes a nice checkerboard pattern. Id imagine that's also useful under artificial light that might flicker at mains frequency as even if the blade appears stationary, the pattern will still vary indicating rotation.
looks different with the neekit eyeball(s) You might see that effect in a hanger with fluorescent lights at night, other wise it's a whirling blur. May possibly have a SPIRAL pattern to it.
There's lots of comments on the mesmerizing checkerboard effect of the spinning props. I hope we realize that that is caused by the chopping frame rate of the video. If you are seeing it with through the nakeet lens of model Mark1 Optical Orb(s) than it looks like a whirling blur. Possibly with a spiral effect.
I've marshalled airplanes in the USAF, specifically A10s. They didn't back up, so I never learned all the hand signals, nor did i use paddles. Also, there's a LOT more to the preflight systems checks. But watching a plane being marshalled in reverse is cool. Wonder how it looks when yoi have to turn them in reverse.
I worked for an outfit that tried to certify a Jetstream with Pratt Whitney PT6A34 engines. Never did get the type certification, I don't believe. I left the company before then.
Ah yes.. garett turboprop engines ... ever heard the Garret ground handlers salute? It's fingers in ear or on headphones/muffs trying to press them to ears due to loud engine. Fuel to noise converter
@@c172215s both engines are critical. When in take off power the counter rotating engines helps to fight the tendency of the engine torque to pull to one side, P-Factor.
@@c172215s I have twin time, 1865 hours of twin time so don’t lecture me on critical or non critical engines. Obviously you don’t understand what he said, the counter rotating engines is not to negate a critical engine. During an engine failure it does not matter what direction the prop is turning, the counter rotation is for take off and climb power settings so you don’t have to use so much rudder input.
Holy shit that marshaller needs a new pair of glasses. He almost put him in the dirt. As soon as that nosewheel clears into the taxiway he should signal the transition out of reverse. They can’t touch the brakes during a powerback; the transition has to be gentle using thrust only. In the process the plane will still travel another 50 feet or so in reverse before finally changing direction. You MUST plan for that; I’ve written up too many rampers whose powerback attempts (back when they were common) ended up with the mains in the dirt. We (Kansas City) had the dubious honor of leading the nation in botched powerbacks.
@@frontagulus look out the window? On the surface it would make sense, right? If PIC opened a cockpit side window and stuck his head out he’d have to contend with 1) major reverse thrust coming right at him from the nearby propeller (at the very least flinging off any eyewear and hurling debris right into his eyes in the process), and 2) ear splitting roar from those incredibly noisy Garrett engines. Besides that, with the engine and wing impeding his sight line he wouldn’t get accurate depth perspective anyway. Hence the need for wing walkers and front marshaller
A whole pile of reasons why. You can’t see behind you. A sudden application of the brakes can put you on the tail. A non-centred nose wheel can swing the aircraft rapidly or damage the linkage. Prop blade damage and FOD ingestion. No reason at all to do this. Especially when there’s marshalers who could have places the ground cart out of the way and guided the pilot to turn around in that space.
They're TPE331's, and they aren't actually direct drive engines. They have a sizable reduction gearbox that reduces 30,000RPM at the input shaft down to 1900-2500RPM at the propeller depending on which variant of the 331 is installed.
@@s4aviator804 ah! That's right.... the 731 is a turbofan engine, found on many private jets. My mistake! Oh yes, that's right. What I was referring to, is it doesn't use a "free wheeling power turbine" it's driven directly by the engines core, not exhaust flow like a PT6, or a Pw100 style engine. That's why you see the propeller rotation start up so quickly upon startup :3
@@mobiusone3923 You got it! I’ve got many hours behind the TPE331 in the Conquest II, and even more with the TFE731 in the Lear. Both are fantastic engines
@@s4aviator804 OH very cool! I was a line tech for 5 years. Honestly, wasn't a fan of the 331, being in the ramp next to it doing gpu starts. The harmonics made my head hurt sometimes. Haha.
There's probably practical reasons for ground operations like that, but it seemed a bit weird to me? Generator guy obviously wasn't organised, took fro ever to disconnect, figure out how to reattach his tug (what?), then drives it into a clearance area to stand there and say, 'hey, watch out for me!'(?). Guy with the battons just seemed to wave them all around without any distinct order, doesn't correct pilot when he wanders towards the power cart.
In the video which is 5.39 seconds duration, upto 4.40 seconds length duration is MERE TRASH, to watch just about 50 seconds, one has to bear TRASH of 4 minutes and 45 seconds. GREAT 😂😂😂

You'd have to look at them through your camera, it's the camera frame rate causing that.

I thought airplanes couldn’t reverse drive
I’ve only seen power backs by 727s and Dc9s.
Wonder where the J41 came from. I worked with them at IAD/United Express-Atlantic Coast Airlines.
They were built in Prestwick, Scotland. I was on the production line for 3 years.
Nice catch! Notice counter rotating props to negate a critical engine.
Counter rotating props to negate yaw, or P-factor

This is but one of many reasons why you don’t do power backs in the first place.
damn i didn't know they allow turboprops to do that. when it comes to power backing only a few airports allow you to do that
All you have to do is change the pitch of the propeller blades.
Why?
Ah because of noise restrictions I see
A whole pile of reasons why.
You can’t see behind you.
A sudden application of the brakes can put you on the tail.

The 331 the loudest
And the best besides the rolls Royce dart.
That's so cool, watching an airplane go in reverse. Eh? Thrust reversers, I know. But still a little weird to watch.
