@Deinacrida Everything control wise is mechanically sound, but it doesn't effectively do what it should. As far as a loss of translational lift is concerned, at low airspeed or in hover (anything below translational lift) you need more power as the effectiveness? of airflow over the disc is reduced. So more power pulled means more torque between the main rotor and airframe, which needs more pitch on the tail rotor to counteract it, which means more chance for tailrotor VRS.

@Deinacrida I stated that horizontal stabilizers lose authority and you're right, it's the vertical stabilizers that do, not horizontal, I don't know what I was smoking that day, i was probably reading something else while I was writing. But their loss of effectiveness in hover or low airspeed can accelerate the yaw, increasing the speed of the tail rotor VRS? situation. This is when there is a total loss of effectiveness. Notice theres no loss of control, but control effectiveness.

@Deinacrida No probs mate, basically in the event of a LTE, theres a few different nasties that can affect how the tail rotor works, whether that be mechanical or an effect of how the outside forces can change in different? circumstances during flight. But as a main rotor can lose effectiveness due to VRS during flight, so can a tail rotor. In gusty conditions wind gusts can travel through the tail rotor in the direction of thrust causing a VRS situation if the heli is moving too slow

This is grim but very interesting. See at 0:32 main rotor sheared off and went skyward - with the mainshaft attached by the looks. There was a person on the summit? near the start - hope they didn't get clobbered by bits! It's obviously a Bell Jet Ranger by the shadow and sound.

@nais26 Thanks for that comment, interesting. I'm? not quite clear on the loss of tail rotor command: So is it only the 'bleed' of power (due to landing power increase) ? How does the 'vortex ring' part work? Is this the main rotor down wash interfering with the tail rotor thrust projection? Doesn't the horizontal stabiliser help with pitch not yaw? Cheers

Perfect example of loss of tailrotor drive. You actually can see the helicopter yaw and the pilot almost emmediatelly does what the emergency checklist tells: collective pitch? reduce to stop yawing. You can hear the N1 turbine speed down, when you listen closely to it. He just is to Slow n low to recover the chopper. Bad Luck beeing in the dead mans curve when tailrotor quits service.

Everyone is an expert.?

definitely LTE----at the? crest the mountain, mountain roll wind is a bitch!!!
By: bill4long. on 26 Aug 11, 00:02:51
How come? the pilot doesn't cuss?
By: DiamondPilotDan. on 18 Aug 11, 23:17:02
LTE? someone please explain this for? me?:)
By: FlyingBoxHead. on 11 Aug 11, 02:40:34
Glad? to see the NTSB guy in the top-comments section,lol
By: nzvfr. on 31 Jul 11, 11:43:56
I think shootbigbird got this one right, altitude is high and it's a perfect spot for the wind to rotor requiring an increase in collective to hold altitude resulting in over pitching and then, oh my gosh there's no more left peddle. thank you for the posting? as it's educational to watch it unfold, hope the punters came out ok.
By: Mmasterson9. on 18 Jul 11, 03:18:24
Wow, I can't believe that none of the comments posted the true cause. It was downdraft rotor, from the 40 mph wind hitting the sharp ridge. The helicopter flew behind? the ridge, into the curling rotor wind and it forced him down to the ground. Glider pilots know all about this rotor because they fly near mountain ridges and they know never to get behind ridges in strong wind.

I find it somewhat strange that comment after comment is about the tail rotor or some mechanics or the other? but no one mentions or tries to find out if these pax in the chopper survived!! Did they?
By: aligerous. on 06 Apr 11, 16:02:32
@obese1konobe How can you tell what the airspeed is? in that right turn?

"A helicopter impacted the top of? Pike's Peak at 14,100 feet mean sea level (MSL). The pilot said he had made a low pass over the summit into a 40-knot headwind before losing tail rotor effectiveness. He then lost directional control and struck the ground." source: dynamicflight.c o m/aerodynamics/loss_tail_eff/

this is one area where fixed wing aircraft have an advantage. you don't often here of wings breaking off fixed wing aircraft but it has been known to? happen but usually due to over stressing the airframe. i hope they survived this

@danielpilot95? would you jump out with spinning blades above and behind you? cause i wouldn't. best case, ride it out
By: danielpilot95. on 18 Feb 11, 23:38:50
@mushatrusha how did u survive and btw is ther anyway to survive a tail rotor failure and if necessary is it possible to jump? out wit a parachute
By: TheTrueStubbi94. on 18 Jan 11, 21:40:18
...this?
By: TheTrueStubbi94. on 18 Jan 11, 21:40:02
Well I think they.... died. But who has? uploaded
By: raptors222222. on 01 Jan 11, 20:53:03
@nais26 Still another name for death.?
By: edcoondog. on 28 Nov 10, 00:59:29
ship was in a continuous left strafe and it sounds like a 206 so more than likely was? lte/tr vrs.
By: ClanDigitalDoom. on 13 Nov 10, 02:21:57
@nais26 You know your stuff.?
By: PureInsanity00. on 29 Sep 10, 02:11:06
@nais26 Oh. Now in English please? :)
