763 Outboard aileron lockout is controlled by the SAMs (stab. trim aileron lockout modules)with speed inputs from the DADCs.The SAMs constantly receive mach no. and computed airspeed signal (Vc) from the DADCs with lockout occuring at--
Vc > 275knts
Mach 0.5-0.58 and Vc>235knts
Mach>0.58
The SAMs also lock out certain flight spoilers as well (4,5,8,9) when the outboard ailerons are locked out.
