Engines fail, autorotate help

[TimeKilla]

I've been trying auto-rotate by cutting the engines at high altitude then restarting APU then engines back to normal flight before hitting the ground I've got that just fine.

 

Now I want to learn how to land using only auto-rotate sometimes I find that spot where It loses altitude dead slow others it comes out of that and starts going down faster than I want, I've been playing with the collective while the engines are shut down it seems to still work and trying to see if hover helps or you need forward flight could someone give me advice? :pilotfly:

The procedure is in the Black Shark Flight Manual, towards the back of the book as to emergency procedures.

 

I have not bothered with this. As-well-as, if I am busted up too much, I just eject.

 

If at all possible I like to RTB and get repaired. If that is not possible, for me, why waste the time? I just get another copter.

 

As to your signature:

==============

300 km/h in straight flight is my rule of thumb, but temperature and altitude will influence the variability to this. Turning I slow down.

 

Flying too high with enemy aircraft around, for me, is not too bright. 50 meters and below is where I usually am. I usually fly at tree-top.

The collective will continue to work even with the engines off. Heck, before you do a ramp start, play with the cyclic and collective and watch the blades move =)

 

Don't try to hover when you cut the engines. It will drop your rotor RPM very quickly, and you won't generate much lift. Forward speed is the name of the game. There's a chart on page 61 (or 4-13) of the flight manual showing what speeds to avoid at what altitudes. Basically, keep your speed up until you're ready to touch down, then pull the cyclic back and the collective up to bleed back the speed.

 

It's very much an art. If you want to upload a track, I'm sure some folks here could take a look at it.

for me, play it like a plane. find a nice road or runway, and land at 150kph. it's easy.

At a farp, requires more skills.

Thanks buddy! I know it's in the manual sometimes its still hard to get you're head around things.

From hover and forward flight, soft touchdowns:

 

The flare on this one is not so well executed. He should have first reduced horizontal speed by pitching up (rotor RPM increases) and then just before touchdown pulling collective to zero out vertical speed. Have a look:

 

That's the training track for autorotation descent without actual landing. Still it contains some numbers to keep in mind:

 

So to sum it up:

• At the start of autorotation put the collective all the way down.
  
• During descent all you have to do is to keep rotor rpm above 80% and speed around 100 kph using the cyclic stick:
  
  • pull back = increase RPM and reduce speed,
    
  • push forward = reduce RPM and increase speed.
    

  [*] At 30 m reduce forward speed by pitching up and pulling slight collective.

  [*] Just before touchdown pull collective more to kill vertical speed.

i bet if they took a blackshark, extended the wings and put forward thrust engines on it, i'd be a decent plane too....

@PhoenixBvo, Thanks great post rep'd :thumbup:

 

@SkateZilla, Got a feeling you're right there.
