1	The use of a slot in the leading edge of the wing enables an airplane to land at a slower speed because it delays the stall to a higher angle of attack. changes the camber of the wing. decelerates the upper surface boundary layer air.
2	The speed at which the airflow over the wing first reaches the speed of sound is known as the critical Mach number. transonic index. Reynolds number.
3	Transonic airspeeds are considered to be from Mach 0.5 to 0.75. Mach 0.75 to 1.2. Mach 0.75 to 2.0.
4	Mach number is commonly defined as the speed of sound under conditions of standard pressure and temperature. ratio of equivalent airspeed to the speed of sound. ratio of true airspeed to the speed of sound.
5	The purpose of sweeping wings back approximately 30° to 35° is to provide aileron control when the root of the wing approaches the critical angle of attack. reduce high-speed drag. minimize dutch roll.
6	Shock-induced separation of airflow occurring symmetrically near the wing root of a sweptback wing may result in a severe diving moment, due to the center of pressure moving aft on the wing and a decrease of downwash on the horizontal tail. a high-speed stall and sudden pitchup due to the center of pressure moving forward on the wing. severe porpoising due to an attempt to recover control while under reverse command.
7	What is the significance of a flashing red ATCT light gun signal? Aircraft on the ground should return to their starting point on the airport. Aircraft in flight should exercise extreme caution. Vehicles or personnel should clear the taxiway.
8	An airplane is climbing at Mach .78. The true airspeed will decrease as the temperature decreases. increase as pressure decreases. increase with altitude.
9	True airspeed is determined by correcting calibrated airspeed for nonstandard temperature and altitude. equivalent airspeed for the air-density variation from the standard value at sea level. indicated airspeed for density altitude.
10	Which is an advantage of flying a jet at high altitudes? Thrust increases as the density of the air decreases. Lower engine RPM's will result in decreased specific fuel consumption. Lower temperatures increase engine efficiency.
