Engine Failure---What's Different

OK, so the engine has stopped.
The question is does your gyro have different flying characteristics when the engine stops?
Is there a difference between a landing with the engine at idle and the engine stopped?


Safe Flying

Re: Engine Failure---What's Different

While I've only done it in training, the only difference I noticed was that if the engine was stopped, pushing the throttle forward only makes the silence more deafening.
I have heard it said that an idling engine acts as 'engine braking' to some extent.

Re: Engine Failure---What's Different

I'm hearing things that our mate PB might be best to talk about this subject, specially of late

Come on PB tell us how to handle these type of situations.

Re: Engine Failure---What's Different

Engine at idle or engine stopped, have not noticed any difference just the silence

Re: Engine Failure---What's Different

Yep,

The characteristics are horribly different - it won´t go up any more, that´s for sure, there is only one way you´re going - down.

What you have to now consider is that your flight path that was, maybe, horizontal is now raked downward at the glide angle of your gyro, and they do vary, a healthy angle to adopt is 45 degrees, though you might be able to go more shallow you could be tempting fate in trying to ´stretch the glide´ and have a horrible sinking feeling where you end up doing a vertical down, or worse still as some have found out, a reverse tail spin down to ground.

As most of you already know I had an out landing at Manilla - as Marcus Horribulus puts it - the ´Manilla Folder´.

I discovered that my #3 inlet valve push rod broke in two after the incident, but I sure as hell lost power, but not totally.

Airspeed,
Airspeed,
Airspeed
and !@#
Airspeed

Maintain airspeed - push the stick forward and allow the nose down.

With mine I adopted an agressive glide attitude and maintained speed at near 50 - 55 kts, then you have large amounts of momentum with which to flare at the bottom. [Prior to this I got to a stage of trying to make every landing an engine out, it paid huge dividends for me, except when my nosewheel collapsed on the ground -after- i tried to taxi through the grass to the roadway.]
I pulled up about 2~3´ off the ground using a technique Ross uses - working the stick backward and forward and did the proverbial postage stamp landing, perfect. Then I made the mistake of trying to move off through ´lumpy grass´.[From this I learned, ´just stop´, itś a bit like ´Just do it´. If you have an engine out, just stop, end of story, it is the safest option of all of them, turn off - tie down and walk out, lest you flop your machine like I did.]

Usually if your prop has stopped youŕe to busy aviating to notice what the effects are other than that you are going down.

Hope this helps,

Cheers,

Nick.

Re: Engine Failure---What's Different

I've had 5 engine outs, my first was on my 1st solo and the other four in marginal country . The only real difference was maybe a little less responsive on rudder, but I found the silence kind of peaceful. Wish it would fly this quiet all the time. I got them all down safely with no damage and found that these are usually your smoothest landings. Must be the pressure to perform. If you don't panic it makes it a lot easier. Just think...I'm going to get this thing on the ground no matter what!

Re: Engine Failure---What's Different

Forgot to mention that my mate who is the Test pilot at Sikorsky and flies everything from F18 to Groen brothers said that if you increase your approach speed by 5knts you can glide a lot further. Faster is better than slower to make that distant clear spot. Ken

Like in most aircraft on glide approach - if your undershooting put your nose down, go faster, glide further ... exactly the opposite to what your heart is telling you
