Description

Please remove ACE auto-rotation, it is unrealistic and makes it much too easy. Pilots in my unit have been hit by an AA missile head on, blacked out/died and managed to land safely. Something is VERY wrong when the aircraft can be landed without engine power or any pilot input, call me crazy. Auto-rotation is a very difficult skill, there is a reason why pilots in real life MUST train on it regularly. Don't believe me? Fire up DCS: Black Shark, shut down the engines mid-flight and try to land it like you do in ACE. I'm here to tell you, it simply isn't happening without there being a massive fireball involved.

Second, the "Air flow speed" indicator serves no real purpose and is unrealistic. (I've never heard of an Air flow speed indicator, nor can I imagine how the information could be acquired for said gauge.) In a real helicopter, the rotor RPM gauge is watched like a hawk along with forward speed and the collective is adjusted to maintain rotor RPM.

Another thing that really bothers me in ACE auto-rotation is how quickly the rotors appear to slow down (at least when I do it properly), yet there is a disproportionate amount of lift. It really breaks immersion.

In short:
  • Decrease collective immediately
  • Maintain 60-70kts (110-130kph)
  • Monitor Rotor RPM and keep it up. (Can easily be heard with practice and gauges in certain Vanilla helis work.)
  • Flare at about 20-30 meters
  • Level out and use collective to cushion landing.

In ACE, I can do several of the "Common Mistakes" and come out fine. In Vanilla, this guide holds true and its a cruel, unforgiving, mistress. (Just like real life) In ACE the guide is more of a gentle suggestion than anything. (As evidenced by pilots blacking out and landing safely.)

Vanilla ArmA 2 Auto-rotation is much more realistic when compared to ACE, unfortunately.

Thanks for reading.

In the meantime you can prevent this behaviour by setting "ace_sys_autorotation_autorotating" variable on vehicle with setVariable to false.

The way you have taught yourself to autorotate (based on your training video about it) in vanilla may seem more realistic, but the actual mechanics of the vanilla autorotation are just as bad as ACE's version.

Uber-simple repro of unrealistic vanilla autorotation:
  1. Start as MH-6, flying, with your unit init being: blah = [] spawn {sleep 10; (vehicle player) setfuel 0};
  2. On mission start, climb straight up until you lose fuel
  3. Once you lose fuel, hold down your 'thrust down' key. Do not gain any forward/backward momentum, just fall straight down.
  4. When about 20-25m off the ground, release 'thrust down' and hold 'thrust up'
  5. Land without a scratch.

I never said it was perfect. :P
And I just did that in ACE and it worked, I didn't even need to let off the decrease thrust key. (Killed the engine doing it, but otherwise fine.)
Also, thanks for the scripting stuff, Dslyecxi, I'm horrible at that kinda thing.

Thank you Stickboy.

On a semi-related note, does wind effect helicopters in ACE?
