Test questions for the Air Force Officer Qualifing Test

Force necessary to overcome gravitational force to keep the airplane flying is termed Lift
Ailerons are used primarily to Roll the airplane
Ailerons are located On the outer edge of the wings
Pitch makes the airplane Go up and down
Bank makes the airplane Roll or turn
The four aerodynamic forces acting on an airplane are Drag, lift, thrust and weight
An airplane wing is designed to produce lift resulting from relatively Positive (High) air pressure below the wings surface and negative (Low) air pressure above the wings surface
Flight Instruments Airspeed Indicator, Altimeter, Attitude Indicator, Veritcal Velocity Indicator
Engine Instruments Tachometer, Ammeter (battery), Altimeter, Altitude in MSL
