FAA ADX Correctly Solved Practice Questions and Study Guide | Correct Answers Included When are inboard ailerons normally used? - answer - Low speed amd high speed flight When are outboard ailerons normally used? - answer - low speed flight only which of the following is considered a primary flight control? - answer - elevator which of the following is considered an auxiliary flight control? - answer - Leading edge flaps what is the purpose of a control tab, such as those found on B727 airplanes? - answer - move the flight controls in the event of a manual reversion what is the purpose of a servo tab? - answer - Reduce control forces by deflecting in the proper direction to move a primary flight control for which purpose may spoilers be used? - answer - Reduce the wings lift upon landing What is the purpose of an elevator trim tab? - answer - Modify the downward tail load for various airspeeds in flight eliminating flight-control pressures. What is the purpose of a wing mounted vortex generators? - answer - delays the onset of dragged divergent at a high-speed and aids in maintainin aileron effectiveness at high speed What effects indicated stall speed? - answer - Weight, load factor, and power loading an airplane with a CG aft of its aft limit will have what impact on performance? - answer - General pitch instability The primary purpose of high lift devices is to increase the - answer - lift at low speeds What effect does the landing edge slot in the wing have on performance? - answer - Changes the stalling angle of attack to a higher angle What is the principal advantage of a sweet back design wing over a straight wing design? - answer - The critical Mach number will increase significantly What is one disadvantage of a swept wing design? - answer - The wingtip section stalls prior to the wing root. What is the condition that may occur when Gus causes swept wing type airplane to roll in one direction while yawning in the other - answer - Dutch roll What is the movement of the center of pressure when the air flow stalls at the wing tips of a swept wing airplane? - answer - inward and forward What should a pilot do to maintain best range airplane performance when a tailwind is encountered - answer - decrease speed At what speed, with reference to L/Dmax, does maximum rate-of-climb for a jet airplane occur? - answer - A speed greater than that for L/Dmax which performance factor decreases as airplane gross weight increases? - answer - Critical engine failure speed What effect does an uphill runway slope have upon takeoff performance - answer - Increases takeoff distance under which condition during the landing role are the main wheel brakes at maximum effectiveness? - answer - When wing lift has been reduced what is a disadvantage of the one step over the two-step process when de icing/anti-icing an airplane - answer - The anti-icing protection is very limited Which procedure increases holding time when deicing/anti-icing an airplane using a two-step process - answer - heated type 1 fluid followed by cold type 2 fluid Which of the following will decrease the holding time during anti-icing using a two-step process - answer - apply heated type 2 fluid what should the de ice/anti-ice fluid temperature be during the last step of the two phase process - answer - cold Free directional oscillation is - answer - a coupled lateral/directional oscillation that is usually dynamically stable. Which freezing point depressants are least effective - answer - Type 1 At the aft CG limit the horizontal stabilizer and elevator - answer - must develop less down force to balance the decreased forward loading. Vortex generators are designed to - answer - delay boundary layer separation If an engine press line is above the center of gravity, it is - answer - stabilizing A headwind which is 10% of the landing airspeed will reduce the landing distance - answer -
