At 3 engine climbout speed plus 50 knots a max bank angle of ______ degrees is permissible.
30 degrees

For the KC-135, ground effect begins about ________ ft. above the runway.
130 ft (about one wingspan)
The KC-135 displays an effect known as initial buffet which is airflow separation on ___________ and is an indication that you are approaching ___________.
The main wing; stall speed
____________ directly affects induced drag?
Ground effect
Approximately ______ % of the roll authority on the KC-135 comes from the spoilers.
60%
If gusts are present, the takeoff and climbout speeds are increased. For heavy gross weights, if flap placard speed approaches or exceeds flap retraction schedule, use the flap placard speed minus _________ knots as the flap retraction speed.
5
_____ degree flap takeoffs are better for close-in obstacles and short runways.
30 degree flaps
Flaps at _____ degrees are preferred on takeoff due to more excess thrust which provides better climb and acceleration rates.
20 degrees
We only have a ____% stall margin on takeoff, limit bank when performance is critical
10%
The rotation go-around (RGA) computer may use a higher angle of attack (AOA) as the basis for the climbout profile due to _________________.
Over rotation on takeoff
