AFOQT Pilot Exam Questions with Correct Answers

AFOQT Pilot Exam Questions with Correct Answers 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 law of motion - Answer-A stationary object remains at rest and an object in motion continues to move at the same rate and in the same direction unless acted upon by another force Newton's Second law of motion - Answer-Acceleration results from a force being applied to an object. The heavier the body, the greater amount of force needed to accelerate it Newton's Third law of motion - Answer-For every action, there is an equal and opposite reaction The aircraft is stationary or on the ground when - Answer-lift=weight and thrust=drag Air Foil - Answer-Wing, propeller or helicopter blade that generates more lift than drag as air flows over and underneath its surface Angle of attack - Answer-Angle between the chord line of an airfoil and its direction of motion relative to air Angle of incidence - Answer-Inclination of the wing or tail surface attached to the fuselage relative to an imaginary line that is parallel to the aircraft's longitudinal axis (the angle that the top of the wing makes compared to the longitudinal axis of the plane) anhedral angle - Answer-Downward angle of an airplane's wing and tailplane from the horizontal when the wings are shaped like ^ its the angle from the top of the point to the two bottom points Altitude - Answer-Aircraft's position relative to it's three axes and a reference such as the earth's horizon center of gravity - Answer-the air craft's center of mass. The point where all of the weight of the machine is said to be counteracted Chord - Answer-The distance between the leading and trailing edges along the chord line is the airfoils cord. Average chord describes the average length of the wing from front to back. THIS IS JUST THE LENGTH
