FS,
1 )If the strobe frequency were slow enough...
Yes, if it were slow enough and the rotation speed was fixed the strobe would work, i.e several positions per second giving the apearance of a slower rotation. However for manouvering the prop will be advanced thus increasing the rotations and back to square one... a variable resistor tied into the throttle control or rev counter might solve that one.
2)Would this association be strong enough that it would not be forgotten by ground personnel....
Proceedures would have to be very clear and strictly abided by, but I would add that on an airfield there are strobes every where wing tips etc, Would ground crew consider another flashing strobe as a passing AC ?
I would love to hear a ground ops take on this?
Where would you mount the strobes?
