1.JaVA_Platypus Posted July 20, 2015 Posted July 20, 2015 When the engine is off, the AoA vane is responding to the input of the stick. It is flapping around like a mini-wanabe-canard. :smartass: Also, the elevators are moving. I don't know if it should do that, because when the engine is off, the hydraulic power amplifiers should not be working. Happy Flying! :pilotfly:
Destroyer37 Posted July 20, 2015 Posted July 20, 2015 The AOA vane could and should be moving even if the aircraft is not running, due to wind. Now as far as it moving with the aircraft powered off and with stick inputs im not so sure. About your elevators moving if you had just shut down you may have enough hydraulic pressure remaining in the lines to "amplify" the control input. Not sure of your specific setup when experiencing this. Please let us know!

1.JaVA_Platypus Posted July 21, 2015 Author Posted July 21, 2015 Well, the AoA vane responds to the movement of my joystick, while the aircraft is static on the ground, no engine running or electrical power switched on. That is definitely not right. I am not sure about the control surfaces if they should move when the aircraft is cold and dark. They might, but the Mi-8 controls are frozen in the same conditions. So I thought it rather strange the MiG-21 control surfaces are moving when the engine is not running nor any (electrical) power connected. They might, but maybe not. Happy Flying! :pilotfly:

I don't know if it should do that, because when the engine is off, the hydraulic power amplifiers should not be working. Haven't noticed the vane behaviour, but the elevators behave correctly - when there's no hydraulic pressure, they don't move indeed. Cold start - they don't move. After shutting the engine off, they will move as there is still some residual pressure in the hydro system left (that's probably what You've noticed). Move the stick for a couple of dozens of seconds, however, and You will see the pitch angle of elevators getting lower and lower... until they stop completely. You can also monitor hydro pressure gauge to see how it's going down. Works the same way in the Sabre.
