Is there a short Mi-8 Landing Tutorial??

[Tempest]

Looking for something that is short an to the point like this excellent Mi-8 take-off tutorial by jobsonandrew

 

http://www.youtube.com/watch?v=ArsJvABZjIY.

 

All I could find were landing videos but nothing walking you through with commentary (ala Wags instructions with the black Shark) or scripted pointers.

Not really tutorials-just displays of talent with landing the Mi-8.

 

Still come in too fast, vortex rings , nothing even close to pin-point accuracy etc etc-something to shorten the learning curve.

My advice is don't have either pitch or yaw sas channels engaged and release hand brake.

Don't worry too much about accuracy until you master the landing itself.

Trim constantly. show your controls helper Right Cntl + Enter. Use steady rudder pressure and feel for the inground effect.

 

Once you get the feel of the heavy old girl it is very difficult to enter the dreaded vortex ring:)

Descent with less than 5 m/s.... :D

Thanks for the input. I'll keep trying. This beast is way harder to land then the BlackShark (don't own the Huey yet).

[McBlemmen]

Like SimFreak said , watch your vertical velocity indicator CONSTANTLY. A good way to practise landing is to come in at a shallow angle , entering ground effect and then transitioning from a hover to a landing.

 

Now i will say i dont actually own the MI-8 , only the shark and the huey (soon to change) , but i spent quite alot of hours learning to land the damn huey and i dont think it can be THAT different.

 

Also remember that you can only enter vortex ring state if you are in a hover or a near-hover (is that a thing?) , not if you have high(ish) airspeed , i'd say about 30 to 40 knots should do. (50 to 70 kmph)

 

When i land the huey , i watch my intruments more then the actual ground. Is this the right way to do it , probably not , but it's good if you're learning.

 

Hope this helps

 

 

Edit : oh , and accuracy comes with experience. Learn to survive the landing before learning how to accurately land. Learning how to hover will also reduce the need to be able to land accurately.

Flying the UH-1 as I please, I first handled the Mi-8 in a similar manner, VRS'ing over and over again.

 

The trick is to accomodate to the high gross weight and fly it accordingly.

With the UH-1 you can no problem just drop the collective and pull the nose up to decellerate, not so with the Mi-8.

The engines will noticably reduce rpm and when you then suddenly need more power as you come to a hover they cannot deliver and you drop into VRS.

 

Plan your approach more carefully, start decellerating early, don't descent too fast and keep the collective at a position where the engines don't noticably power down.

 

Attention to those power stages combined with a handling suited for such a heavy helicopter cured about 99,9% of my VRS.

Hope this helps somewhat!

I can't make videos but here is a track of various landing scenarios so you can maybe see from a cockpit view where the controls are at various times and take control to try yourself.

Hope this helps and apologies for the carrier landing I forgot it was moving at 20 knots and the roof I accidentally trimmed when my attention wandered:music_whistling:

Cibit I really appreciate the TRK file. :thumbup: I can see that I have to lower my speed and come in with the nose not to high (to bleed off speed) ala KA-50.

I see what is said about anticipating-but what did you do to bleed off speed?

Lower the collective as you keep moving forward? I paid particular attention to red smoke marker and building roof landings.

I'll try runway/apron landings but will have to work on bleeding off speed.

You landed on everything except a moving train (but the aircraft carrier was moving. :))

 

I noted you always had it trimmed a bit to the right to.

FWIW I'm using a Saitek throttle quadrant and AV8TR stick which for me works fine. (I can land a KA-50 at night on a FARP).

[Cibit]

To bleed off speed just get used to lowering collective and pulling back cyclic together. I am not sure if its apparent on the replay but trim little and often. keep the nose level or slightly down and vertical velocity 2-3 m/sec. As long as you have forward momentum you should avoid VRS. Note the speed guide when you go into near hover. The scale starts at 40 Km/h and is invaluable for judging forward speed.

Other than that practise and trim and constant corrections with collective and rudder inputs. With regards normal flight I would engage my Stability assist when at desired altitude and on correct general heading:thumbup:

[GunfighterSIX]

If your just getting into the Mi-8 keep your SAS on! The aircraft is designed to be flown with it. Once you get good you can practice with out it.

[Cibit]

Sorry I perhaps was not explaining myself very well. I would never advocate doing anything with the Hip without pitch and yaw stabilizer on. For any landings, takeoffs and major course and height deviations I do not engage the heading and altitude stops as this fundamentaly changes behaviour of the craft when the operator needs complete authority.

This however is only how I do it, whether it is correct procedure or not I dont know;)

 

Just reread my first post. How to give shit advice :doh: so sorry for this ineptitude

[Tempest]

Ah don't worry. I appreciate all the advice. My takeoffs are pretty smooth but I I have on the heading indicator and pitch and yaw stabilizer on and control helper on -and always trim. Landings gonna work on those.

I'm on summer vacation the next 2 weeks. But I will be revisiting how to land when I get back and post a trk file on landing on a runway and a FARP in the future. :smartass:

Descent with less than 5 m/s.... :D

 

Well I had a vortex ring at like 0,5m/s, it just suddenly fell like a brick while trying to get into a hover. But well, it was my first real try now and I'll probably see why it happened soon :)

[esb77]

Start out treating the Hip as a funny looking fixed wing that needs a lot of rudder input. Take off and land like a fixed wing plane would. Feel free to use the whole runway length, though you probably won't need it.

 

From that starting point, gradually practice getting more precise with where your wheels touch down, and making slower and shorter approaches.

 

Keep practicing carefully and your landings should become more and more helicopter like, and you shouldn't run into problems with VRS surprising you.

 

Another thing you can do is a lot of hover check and hover taxi practice.

 

I find that the key thing are the VVI gauge for descent rate, and also the collective pitch indicator.

 

When you hover check before takeoff, note what your rotor blade pitch is, and realize that that's roughly what will be required to not fall out of the sky when you slow enough to loose translational lift when you land.

 

It can be a big adjustment, depending on load you might need 5 to 8 degrees of collective to hover, but 3 degrees is often more than enough when you're coming in on your glideslope on approach.

 

I've seen other more experienced pilot say on the forums that a lot of people who think they're dying to VRS are actually just not increasing collective (and where applicable also engine power, not a worry on the Mi-8 where the engine governor will handle it as long as you don't do crazy things) enough when they transition from flight with ETL to a hover.

 

If you have the option it's not a bad idea to try to get low enough for ground effect to kick in (roughly 7 to 10 m agl for the hip in DCS) before slowing below about 45 km/h.

 

Or practice going from normal flight to hover and back again repeatedly without loosing altitude in the process (or at least not descending faster than 3 m/s). That will teach you how to manage the loss of translational lift without loosing control of vertical speed. Practice at 1000m until you're good at it, and then landing should be quite manageable.

Descent with less than 5 m/s.... :D

 

Looks funny, but this is the ultimate truth, when it comes to landing with Mi-8. The rest is unsignificant. :thumbup:
