Chopper Crash Video

I heard the pilot was flipping rapidly through a manual through that final 100 ft saying, "Flare....Flare....Fl...Flaps....FLARE! HERE IT IS!"

Note to pilot: use more collective!!!

[godfrog 2]

I cant remember what its called but a helicopter can get caught in its own down wash and it wont go back up unless there is enough altidude to zero the collective and pitch the nose forward at about 45*. This is what I read anyway. any helicopter pilots to coment on this?

I officially hate DSL. It posted twice. Sorry.

Shit happens. And it usually happens because of physics.

Looks like quite a bit of coning on the blades before impact. Pulling more collective would have probably just kept the pilot busy until impact.

Agree with Slotperfect; vortex ring state. Sometimes called settling with power, too. Either way, if you're not high enough, it's going to hurt.

Vortex Ring State

Yep:

"With VT 406, CFB Shearwater, NS, in 1982. Still with this unit when it crashed on 4 August 1991 at air show in Schenectady, New York. Aircraft approached landing from a high hover, and apparently entered ring vortex state during descent, resulting in sudden and large increase in sink rate close to the ground. Originally classified as Category B (repairable), but re-classified as Category A on 21 August 1991. To Aircraft Maintenance Development Unit at CFB Trenton on 25 August 1991."

I meant use more collective before that crap even started... why get into a mess like that in the first place?

isn't the technique for a long vert decent to use higher rpms and then finesse the collective?

Rotor RPM is pretty much constant in helicopters, not something the pilot manually adjusts. Generally they just try to avoid long vertical descents and come in at shallower angles with more airspeed. Safer in case of engine failure too.
