Our props if you manage to get them into beta in the air they won't come out
Hmm, interesting. What aircraft type please MJ?
Yes, all reversing systems I have flown have some kind of interlock to prevent, or at least reduce the likelihood of entering reverse blade angle in flight. Some are more effective than others.
I can say from co pilot experience that a DHC test pilot can get a Twin Otter from 6000 AGL to down and clear, in less than 2 minutes, with the help of reverse -
that was a ride!
As a real drift, the DC-8-63 allowed approach with the inner two engines operating in reverse thrust. It came down quickly doing that!
