Short Takeoff (STO)

The STO can be used for the widest variety of aircraft configuration, weight and runway conditions provided that crosswinds remain within specified limits.

Jetborne/Semi-jetborne Takeoffs

All jetborne and semi-jetborne takeoffs being with a takeoff procedure and end with an accelerating transition to wingborne flight. The transition point between the takeoff procedure and the accelerating transition procedure begins once the aircraft is off the ground, the wings are level and the vane is centered. At this point, attitude and AOA can be safely increased and the Accelerating Transition can begin.

CHECK
a. MPCD (Left or Right) Select ENG

AS REQUIRED
a. Place water switch to TO and note RPM rise.
b. Reset RPM to top end of acceleration band.

9. Nozzle/Flaps/Duct Pressure

CHECK
a. Set nozzles momentarily to STO Stop and check angle
