That is seriously impressive.

Yes, a competent rotor pilot with adequate time in type.

That looks very dangerous!

For a competent pilot with adequate familiarity with that particular ship (type) in decent weather conditions it should be no problem.

Those that can, do .

The guy or gal stepping out of it must be aware of the pilots skills. Neat clip.

It looked like people heads and snow banks were pretty close to the rotating blade....a gust of wind might catch out even a skilled pilot.

I expect that you have seen some impressive rotoring.

Only shot gun .

I was in L.A.P.D. Air Support awhile and had some fun ride alongs ~ always take P.D. ride alongs on "Mothers Day" when things are popping in the Ghetto / Barrio .

I didn't realize a chopper could fly on it's side until I looked out the side window and was looking straight down at a perp .

Fun times to say the least, not for the faint of heart

.

Forget about "auto - rotation", it's B.S. ~ once the engine or tranny quits a chopper has the glide path of a set of dropped car keys .

I'm a student rotorcraft pilot, have about 80 hours with 10 solo hours so I'm not presenting myself as an expert but I do have some actual stick time experience.

If I had a choice between facing a engine failure in a light plane or a rotorcraft I'd take the rotorcraft every time. You are correct that auto-rotative descents are pretty steep, typically they'll provide a 1500-2000 feet per minute descent rate but when you execute the flair and land you can put down a helicopter in a much, much smaller patch of land. The ground speed of an autorotation landing is typically 4-7 MPH and with a headwind you can do them with 0 forward airspeed easily. Landing in even moderately sized parking lots is pretty easy and a football field or park is a piece if cake. Not so with a fixed wing aircraft. If the transmission fails its a different story, you're pretty much a brick if the main rotor blades lose RPM.

The video looks pretty fishy to me, the helicopter doesn't seem to be generating much downwash? You have a disabled guy on the side of a snow-covered mountain with a 40 degree slope and as a pilot you're going to subject the person to 100MPH downwash winds? I'd be concerned about blowing the survivor down the mountain before I could off-load the rescue crew member. I don't see any snow blowing down the slopes? When you land a helicopter off-airport there are a whole lot of sand, sticks and brush that gets blown around when you're about 1 rotor diameter off the ground and in ground effect. Not saying its a fake video but it seems a little weird to my eyes.

I agree with Larry, if you had calm winds it wouldn't be too hard to execute the hover with enough stability to make it relatively safe. If you had gusty winds or an engine failure it would be an entirely different matter.

The helicopter in the Video is a BK117 or an EC145, dual engine - very tough and powerful machine. Just what you want in that kind of situation.

Yes Tim ;

In a controlled environment it's peachy .

I've seen several crashed L.A.P.D. choppers, all of them were flying routine patrol and were expertly set down with no loss of life, in every case the helo was destroyed or damaged beyond repair .

One time it hit the deck so hard it bounced back up and landed across the street in a liquor store parking lot, more or less on top of a car (Ford) a Hispanic guy had just scambled under, he was coming out the store's door with his shortie in his hand when the helo came down across the street .

IIRC he wasn't badly injured .

The instructor for my Private was a police helicopter pilot for many years. He was also the helicopter pilot on the old “Dallas” TV show. In fact that was his helicopter on the show.

His viewpoint for emergency landings was the same as Tim’s. His contention was that you can drop a helicopter most anywhere and flair at the bottom. He did not like night flying fixed wing, but had no trouble with it while rotoring and said he had done real emergency landings several times while rotoring but never for real in fixed wing.

I think I'd not want to do a night flare landing.

For my rating I have to log 3 hours of night flights. The last night flight I was doing over the desert east of Mesa, AZ and it was very, very dark out there.

When I'm flying in the daylight I've been trained to constantly evaluate the terrain and keep potential landing sites in view in case of sudden engine failure. As I'm flying out over the inky darkness at 800 feet AGL my thoughts started to drift to how to handle emergency nighttime landings in a desert situation where you can't actually see anything on the ground.

I ask the instructor how nighttime emergency landings should implemented. He replied that the techniques are exactly the same as daylight 1) reduce collective to lower the pitch of the main rotor blades to preserve main rotor RPM, 2) aft cyclic to level the ship and 3) right pedal to counter the loss of torque and enter into a standard 55 knot auto-rotative descent.

This is all normal but then he added the special instructions for nighttime landings..... He continues 'When you get to about 150 AGL turn on your landing lights.... if you like what you see execute your normal flair keeping in mind that your depth perception at night isn't as good as the daytime'.

So I ask well what do I do if I don't like what I see?

He replies 'Turn off the landing lights'.
