Auto-rotation is possible

Recommended Posts

HellToupee had mentioned this in a thread in the Addons & Mods forum. But I'm sure not everyone knows about this yet...

Pressing and holding "Z" immediately after the engine loses power will keep your rotors spinning while you are descending. Just like in a real helicopter, where you would bottom the collective directly after loss of power to initiate an auto-rotation. You are able to maneuver the helicopter while descending. All you have to do is flare before touching down.

You can easily practice this by shutting off your engine in mid-flight. Just be sure to hit "Z" and keep it held down. You have to do this immediately or you'll crash and burn.

I've been practicing this by flying over a shilka until he kills my engine. After quite a bit of practice, I'm now usually able to safely land somewhere. smile.gif

Every now and again, it doesn't seem to work. I believe this might be due to excessive airspeed when the engine fails.

I'm impressed by this feature, and I don't understand why no one from BIS has mentioned it.

Thats sweet! Although I could only do it once while moving and whenever I wantes while hovering, Im sure Ill get the hang of it. Lata

You guys should have tried the EnemyStack sample mission here

It starts off with you having to do an autorotation (on the west side).

USMC marker addon 1.2 required. smile.gif

Actually if you arent having and engine trouble, the engine can be shut down while you are moving downwards (your vertical airspeed indicator is below zero) and the rotor stays running, no buttons needed... Ofcourse you need to cut the throttle.. by pressing the 'move down' key, which defaults to Z I suppose.. Im playing with a Hotas system so I don't have to screw with my keyboard.

Autorotation was already discussed in this thread a while ago.

You should have to obtain airspeed to maintain the rotor RPM to proceed with the auto-rotation or else the rotors would stop or slow too much.<span id='postcolor'>

Actually the helicopter rotor can autorotate at zero airspeed, and even at negative airspeed. The force that keeps the rotor spinning is not the forward speed, it's the air flowing upwards through the rotor during the rapid descent. For this to happen the rotor blade pitch must be set to zero (even negative in some helicopters) so it will produce no torque.

Yeah, you're right about that, Spitfire.

I don't know what I was thinking. tounge.gif

Appreciate the informative post. biggrin.gif

Now we just need AI that doesn't bail out before the player and which attempts to land a heli with engine failure just like this when being pilot. smile.gif

If your going too fast, it wont work. And I thought I had done this before, but I just thought it was more lag or a glitch or even a nice script in the map. But hell ya, now I know I can do it whenever I need, thx man!

That and some kind of warning light and/or sound that tells us when engine fails cuz most of the time when I hear it slow down it's too late to do it sad.gif.

Suuure, smile.gif it can autorotate

but the rate of descent could be a problem at 0 airspeed. -ve airspeed is better than 0, if you know what you're doing.

You are not going to get any good lift depending on initial altitude.

it's good enough, but i would prefer a realistic one where you come down with decent forward speed. In real life we would come down in a gradual descent and instead of having a nasty bang when we hit which is the thing that kills people we prefer to go running along at 60 or so knots and just stop slowly. in urban areas this is hard to do because you can't manouver a lot and you need a straight flat place without population - deserted roads are your best bet but as like that chinook in germany it doesn't always go to plan.

biggrin.gif I think anyone prefers that non deadly approach.

well there are some people who like to do it the OFP way in real life and they have sore backs!

crazy.gif you are kidding right? I mean, if you don't get any airspeed, there is no way you can actually slow your rate of descent unless your blades were at a very high speed already......

well i've heard stories of having overtourque trouble while hovering in storms and then they lose an engine and from zero airspeed all they can do is try and dive towards the ground/water and pull out quite sharply but it's hard to calculate your momentum that fast so they might come out to high and plop down or plough into the water/ground at a steep dive. A big problem with doing this over big waves is yo don't know where the trough is and you might plan to hit the tip of the wave and miss and then fall *waveheight* feet (not far but with a full load and waves coming on top of you - not good)

But with practice this happens less now.

I can imagine... kind of like making a perfect braking point in F1 from 340Km/h at the first and only try you get.

fuckin sweet now i can in fact crash land any aircraft in OFP

I would like to post my findings:

Auto rotation in OFP can happen at any speed as long as you have under 75% collective applied (half ascending power).

I've tried it many times and this is my theory.
