Question about flattering when going from forward flight to a hover

[MR_BURNS2]

Hello, i bought the Hip when it was released, but didn't get into it until recently after i saw this video:

 

 

Iam therefore fairly new to helo sims, altough i played some BS.

 

Anyways, in my trials i had a lot of flattering in certain flight states. Upon investigation i learned about the Vortex Ring State, how to recognize it and how to recover from the more severe cases.

 

However, i still have a little flattering when transitioning from forward flight to a hover. As i understand it this happens because i lose the lift from forward movement and need to apply more collective, but even if i increase collective at that point i get some flattering.

 

Do i have to increase collective so much that i will actually climb a bit?

 

Is my VVI a simple air-pressure only one with the info lagging a little behind real time, meaning that i have to anticipate the loss of lift and apply more collective earlier?

 

 

Is there another possible cause for it, or is it maybe normal?

 

 

Another question, is there somewhere a english manual for the Hover and Low speed indicator?

Yes.

 

Do you perhaps mean fluttering? If yes, then this is normal. It is caused by part of the rotor disc still being in calm air from forward movement, the other part being in the turbulent air caused by the rotor. Once you come to a hover, this should stop as the whole disc transitions into the turbulent air.

It took over 15 hours flying just to prevent the dreaded VRS, it took a whole lot more to be able to land where I want without losing my tail. It is very rewarding once you mastered it:)

 

The Mi-8 docs folder includes the Mi-17 english flight manual.

 

WTF it is no longer contained in the documents? Can we have it back please Belsimtek :thumbup:

[lmp]

The shaking is normal, you don't need to worry about it. As long as you can keep the sink rate under control and not develop VRS, you're good.

 

Welcome to the family ;).

I noticed that the Mi-17 manual was removed as well. Why?

Also, here is the DCS version of that video above :)

The pilot seems in control, however he also seems very irresponsible. The plain on the ground basically tries to get away from the scene before accidents happen. He wobbles allot and risks a bunch of tail crashes. I hope for the pilot the flight authority doesn't pick up this video. He will loose his licence.

I’d blame the flight engineer.

Thanks guys, i have some 5 hours in her and feel fairly confident, my autorotations also work thanks to that tough SOB of a tailskid. :smilewink:

Am i the only one who prefers to fly her without trimming her at all unless on longer-range transit?

 

As for the DCS vid, what the heck? How? I'am baffled...

In Soviet Russia, you punish Flight Authorities...

No seriously, he´s a chopper pilot, chopper pilots are just cooler, especially russian one´s.

Typical ****ing pilot response .................. :thumbup:

Flattering will get you anywhere ;)

I have one more question for you guys, regarding VRS during transition to a hover.

 

Initially i tried to counter VRS by gently increasing collective at the right time, which i understand is the way it is supposed to be done.

 

But i recently involuntarily pitched back with cyclic, instead of increasing collective, and the result was a much smoother transition then i ever achieved before without practising for some 30 minutes. Granted, the pitch attitude changes rather significantly but i stayed steady at my altitude and my tailskid came nowhere near the dirt. I also came to a halt over my intended landing spot much faster without looking too awkward.

 

The question is, is this the way people do it, or is it just me?

Do you use collective only at that moment, or is there a little bit of cyclic pitch-back movement for that purpose as well?

Interesting point.....I'll try this later and see what happens :thumbup:

 

I'm struggling with VRS on the Mi8 too.....Huey I don't have any issues with it.......but boy is the Mi8 a different beast. Very twitchy for such a big helo.

I use a combination of both pitch and collective.

As I slow using the cyclic I reduce the collective and using incremental movements on both find that this gives me a smooth transition until in ground effect gives me the cushion to hover and slowly set down.

But practice is the key and because everyone has different hardware and settings you need to find what works best for you:)

Dont forget to disengage Altitude and heading channels before starting your descent
