The new plane movement actions introduced with the Jets DLC are great, however there's one missing I think would be very appropriate to add; a "Full thrust" action. Basically, you press the key, it instantly sets the thrust to 100, you release the key, and it stays at 100.
The "Brake (Analogue)" action sets the thrust to 0 and stays at 0, and the "Thrust (Analogue)" action sets the thrust at 100 but reverts to 0 on release. Hence, a "Full thrust" action would fill the missing gap.
