Video and simulator footage of VRS and LTE

[Rabies]

Maybe this footage has been shown before. About three minutes in, is shows Mi8 simulator with the external view of the a/c but with cockpit instrument viewing panel. It is interesting to watch, however the narrator is speaking Russian. Maybe one of our Russian DCS pilots can give a quick translation.

No VRS there, looks like just various ways to lose tail rotor authority.

I wonder what the recovery procedure, if any possible, there is should one loose tail rotor effectiveness?

AFAIK - immediately reduce collective

 

• landing if close to the ground and it's safe to do so

 

or 

 

• increase forward speed (re-enter translational lift)

• re-assess power available/wind direction

• divert (or re-attempt landing if safe to do so)

 

 

The problem with LTE is that, near the ground, the instinctive reaction is to increase collective, which further reduces the tail rotor's effectiveness.

 

Note: Although the DCS Mi-8 models torque and weather cocking, it does not model LTE due main rotor vortices or tail rotor VRS due to crosswinds etc. AFAIK DCS's tail rotor is much more effective than the real when operating with an adverse cross/tail wind.
