The Catapult Commands should be...
Catapult (arm/disarm) SHIFT + I
Launch Bar (extend/retract) SHIFT + U
Catapult Trigger SHIFT + SPACEBAR
If you have any of these keys assigned to something else just change the previous assignment and incorporate these. Hope this helps.
P.S. Never used the "Clear Pitot Tube" in FSX or real life flying. Strange command I must say.


An Aircraft Mechanic only needs two tools, Duct Tape and WD40.
If it moves and it's not supposed to - use the Duct Tape.
If it doesn't move and it's supposed to - use the WD40.
