Jetstream 41 Engine start

megusta este video super nitido

[wdwron08]

I have seen 727's DC-9's and MD-80's Push back on it's own Power but Not a Turboprop. That is amaizing

[freddielaker2]

I want one of these for Christmas, In a previous like I used to clean these on a turnaround at Norwich.

[FL065]

holy engines! pt6?

[ayhannozden]

geri manevra yapabiliyor ilginç

[oscarfereira]

Just awesome!!! Reverse!!



[realvanman1]

Is an external power supply necessary to start the first engine? Then the first engine's generator is used to start the second engine? Do they not carry sufficient battery power for an engine start? I'm just guessing this since I saw a cable connected during the first start... Would love to know the details.

[fuzzboi77]

@realvanman1 Generally, for this aircraft, yes. There is only a battery supply which is not a good idea to use all the time because you need it to program your avionics and cabin lights :P unfortunately, this aircraft does not have a APU so batteries are the primary power source. Again, though the avionics must be OFF for engine start regardless, they are on before engine start because your planning your route. Thus, its a much better idea to save the battery power for a rainy day!

[Michael55443]

I had no idea a prop plane could back itself out!

[ithinkimtj]

@Michael55443 reversing the propellers?

[Michael55443]

@ithinkimtj Again, I didn't know they could do that.

[etikem]

@Michael55443 yes. they can by reversing the proppelers and by a turbine engine aircraft they can do it with thrust reverser

[crichey1000]

How'd you know that?

[elyasf]

On the front, it looks like concorde!!

[Critter145]

The sounds quality is great! Thank you for blocking out the wind and stuff!

[747johnz]

LOVED IT

[shaunsprogress]

Pushback with engines running is prohibited; yet one much use reverse thrust to disengage the start locks, might as well use that to push you back!!

[djomercohen]

its a great aircraft for short flights but it isn't able to fly that fast, it reaches approximately 250 knots (450 kph). it should at least be able to fly above 500 kph

[haitiano1982]

it's my plane and i do with it what i want to. so stop complaining about the powerback already

[mjd4277]

Now that was cool!! I 've only seen a powerback done once on a TWA Boeing 727,but this the 1st time I've ever seen one done on a turboprop!

[elcalamarense]

@mjd4277 i saw a caravelle do it in Bogota Colombia,they say that the engines get to hot too quickly,is it true?,im not a pilot,just crazy about planes

[Airshow2010]

I thought it's also against the manual to use reverse thrust to back up on a Jetstream 41. In the manual it said that it could damage the engines (reverse should only be used when condition lever is in the flight area: 95-100% because it might melt the core, unless this pilot pushes the condition lever from taxi to flight while on the ground-makes the plane louder and use more fuel) and starve the air intake (small gap beneath the propeller) by pulling air out. Hope they know what they're doing.

[mojorichie]

@Airshow2010 On a Garrett motor it's either off or freaking shreiking loud like a swarm of hornets at 100 rated RPM. and yes you can go into reverse pitch without problems.

[grooteschuur62]

This plane's backing up??????

[shadowblade145]

@grooteschuur62 Yup ^_^ Reverse thrust is awesome isn't it?

[tysontube290]

isnt reverse thrust prohibited for push back

[Frederf220]

@tysontube290 You're thinking of "pushback prohibited with engines running" meaning you don't push the aircraft backward with a towbar or a tractor while the engines are running. Reverse thrust for backward motion is not pushback.

[tysontube290]

@Frederf220

man the pilot send the engine into reverse thrust, and thats prohibited while in the pax. area

[MISSIRES]

@tysontube290

For Planes with Turbines :) 737 and this kind of planes :)

[wef3838]

ha ha thats awesome

[TheNoergelman]

I like the sticker on the J41 Panel. It says "Pushback with running engines is prohibited". That´s just funny.

[Matzeh84]

@TheNoergelman Well, pushback.. what you see in the (excellent) vid is a powerback ;)

[PuffMac]

@TheNoergelman That's why they're not being pushed back (pushback), they're moving back under their own power (powerback), two different things.

[Gaanmaree]

Good stuff...thanks for sharing!! The head on shot reminds me of the Concord.

[andysim212]

very nice video, i love all props hehe.

[hrbear]

@andysim212 Me too! The beauty of the classic. He he he :)

[FSXSuperboy]

Wow reverse thrust for Pushback! : D

[airplane82]

love that sound!!!

[johnnybroom]

It all depends on the aircraft, company, and airport. All three are reluctant due to the risks of foreign object damage, potential danger to apron workers, and controlling the aircraft (an immediate stop might result in the aircraft being tipped on its tail!). Also, getting a bit technical, if any forward thrust is applied during powerback, it would immediately convert reverse n1 into forward n1, which could be quite unstable. Generally, reverse is only used to slow the aircraft on landing.

[pimpmytafel]

One of the cool things about turboprops is that they can (as seen in the video) use reverse thrust to pushback, whereas jets cannot.

[metalcoyote81]

Some jets can

[Avantime]

NWA's DC-9s do it quite often as well, it's called a 'powerback'

[djungbremen]

Yes, the power back is possible, but I didn't know they are allowed to do that here in Europe.

[federalfsx]

i think its very rare.

[Matti737]

great vid!

[lilmissglentoran]

Loving the turboprops moving backwards and forward (or is it an optical illusion) as they sped up

[thedtothed]

thats an optical illusion like u said

[BIMMERKID2]

Its the doppler effect i think...

[BIMMERKID2]

its the doppler effect i think... or shutter speed .. the camera can not catch fast enough the spinning of the blades

[secret00agent00man]

@BIMMERKID2

The doppler effect is sound.

[assailant85]

@BIMMERKID2 doppler is sth very different, has something to do with relative speed of the object. this is just because of framerates, in RL it would be because the eye can only see 24 fps, so if the rotation of the blades are for example 2400 1/s it seems like it's standing still, 2401/s -> it's spinning slowly in one direction, 2423 1/s in the other. but I don't understand when exactly it changes direction, maybe in the middle...

[GallerySouthwest]

Well done mate - Cracking video.

[airfoxtrot2006]

Thats a really cool startup well done!

[davec154]

Really good Chris! I dont recognise the spot where you took this from, but you sure get close to the action!
