flight controls on jet transports

[Da-20 monkey]

some ailerons are locked out at high speed. However, the throw on the remaining surfaces will be the same.

OK, do some aircraft have an input from the pitot/ static system for this, or is it only ram- air pressure that keeps them closed at high speed?

Spoilers do produce yaw in the proper direction

Thanks for confirming this Intruder. Much appreciated.
