I had an actual stuck collective once. What I did was get on the back side of the power curve by climbing to an OGE hover. There the power required exceeded the power available. I. Stayed below. effective translational lift , and ended up in a 5 foot hover when I hit ground effect. At that point is where I reduced the throttle.
So that’s a great demo. When rolling off the throttle, what are you teaching your students to use as a minimum safe rotor speed? Do you accept the low Nr horn as the minimum, or some other figure? Running on to anything other than smooth ground must add to the excitement somewhat!
Good question! It all depends on the aircraft type and requisite operating limitations and restrictions. Generally though, we use the minimum power off rotor limits as a guide. The low rotor indication in this aircraft initiates at the minimum engine RPM limit which is why you see the Low RPM indicator flashing.
I'm curious... why does the chopper seem to yaw left and right so heavily? At least on the camera it seems to be heaving left and right a lot...I don't see the anti-torque pedals moving a lot, so what makes that yaw motion so pronounced?
That is caused by a combination of throttle adjustment (adjusting rotor RPM to control descent) and a gusting crosswind during landing. The gusts of wind caused the yaw oscillation. It is more pronounced on camera though.
Aviation enthusiast/noob here. Does this mean the collective was stuck in the same position for the entire duration of the video? How do you control the decent in these cases, with power?
Great question! Yes, the collective remained in the same position throughout the video. Descent is controlled using a combination of forward cyclic and throttle reduction. Reduce Rotor RPM (reduce throttle) and the aircraft will descend. Forward cyclic will also cause the aircraft to descend but will increase airspeed. Shallow approach, gradually reduce airspeed and throttle to land the aircraft to a run on landing.
@@TrossachsPhoto Very similar. Throttle is used to establish descent rate and cyclic for airspeed, however the cyclic is also used for the descent. Forward cyclic, increased airspeed and descent. It becomes a balance between cyclic and throttle to maintain a stabilized approach and rotor within limits.

Belo voo. Parabens. Um dia sonho em realizar em ser um piloto . Deus no controle

Perfeito.
Thanks for the comment. Glad you like it.

@@angels1aviation920 Does this mean you're coming in like a fixed wing approach, pitch (cyclic) for airspeed, and throttle for glideslope?
@@TrossachsPhoto Very similar. Throttle is used to establish descent rate and cyclic for airspeed, however the cyclic is also used for the descent. Forward cyclic, increased airspeed and descent. It becomes a balance between cyclic and throttle to maintain a stabilized approach and rotor within limits.
@@angels1aviation920 Thanks for the answer!
Such a job well done, was this a simulation or the real deal??
Thank you for the comment. This was a simulation but the collective was immobilized by the instructor the entire time.
