AFOQT Pilot EXAM PRETEST QUESTIONS ANSWERED CORRECTLY

AFOQT Pilot EXAM PRETEST QUESTIONS ANSWERED CORRECTLY 2 Types of Aviation - ANSWER Civilian & Military Fixed Wing Examples - ANSWER Fighter jets, bombers, civilian jets and corporate airliners Rotary-Wing Examples - ANSWER Helicopters, gyro-copters, and tilt-rotor flying machines Aircraft - ANSWER Machine supported aloft by lift created by air flowing across airfoil, wings, propeller, rotor blades or buoyancy Civilian Aircraft categorized as - ANSWER normal, utility, acrobatic, commuter, transport, manned free balloons, special classes Military aircraft are categorized based off - ANSWER of the mission that they perform Flaps - ANSWER increase wings surface area and augment (increase) lift to reduce air speed Spoiler - ANSWER Hinged panels that move upward after landing to destroy lift Air Brakes (Speed Brakes) - ANSWER Decelerate the aircraft in flight and increase the rate of descent Spar - ANSWER The main structural member inside each wing These run the length of the wing Ribs - ANSWER are attached perpendicularly to the spar to provide more support and strength Wings of most planes that fly below the speed of sound - ANSWER Are shaped perpendicular Wings of most planes that fly above the speed of sound - ANSWER are swept back to delay the drag of air compressibility. Swept wings increase the performance on high performance planes Delta wing - ANSWER This is a triangular shaped wing Variable Geometry wings - ANSWER The wings are positioned perpendicular at take off, landing and low air speeds, then move to a swept position when flying at high speeds Planes that take off and land on water have - ANSWER Floats. They will take off and land on both water and land because they have retractable wheels 4 main aerodynamic forces acting on an aircraft when airborne - ANSWER weight lift thrust drag Total weight force acts through the - ANSWER Center of gravity Lift - ANSWER The force that counteracts the weight and causes the machine to rise Produced by air foils Thrust - ANSWER The aircraft's forward force. This is created by its engines Drag - ANSWER What opposes thrust Rearward acting force caused by air flow passing over the aircraft's structure and becoming disrupted Total drag - ANSWER Sum of its profile drag, induced drag and parasite drag Induced drag - ANSWER Product of lift. Stationary aircraft to not produce this. Parasite drag - ANSWER parts of the aircraft that do not contribute to the production of lift produce this when the machine is moving. (Nose, fuselage, landing gear, rudder) Bernoulli's Principle - ANSWER Increase of the inviscid flow of fluid resulted in a decrease of static pressure exerted by the fluid Conservation of mass - ANSWER A fluid's mass cannot be created or destroyed within a flow of interest. Conservation of momentum (Mass x Velocity) - ANSWER cannot be created or destroyed. It can be changed trough applied force. It is conserved in all 3 directions (laterally, longitudinally and in terms of yaw) at the same time Newton's First
