ASTB-E exam 2023 with 100% correct answers

Most planes have some version of: - correct answer 1. Fuselage 2. Wings 3. Tail assembly or empennage 4. Power plant 5. Flight instruments/controls and control surfaces Fuselage - correct answer Contains the cockpit (where pilots and flight crew control the aircraft's operations); the cabin (if the plane carries any passengers); the cargo area; and the attachment points for other major airplane components (wings, tail section, landing gear) Truss - correct answer fuselages use steel or aluminum tubing in a series of triangular shapes (called trusses) to get necessary strength and rigidity. Monocoque - correct answer use bulkheads, stringers (run the length of the fuselage), and formers of various sizes and shapes to support a stretched or "stressed" skin Airfoil - correct answer an aircraft part or surface that controls lift, direction, stability, thrust or propulsion for the aircraft. Monoplanes - correct answer airplane with one set of wings (almost all planes are monoplanes) Biplanes - correct answer aircraft with two sets of wings Chord - correct answer distance from the leading edge of the wing to the trailing edge Chord Line - correct answer the line from the middle of the leading edge to the trailing edge; cuts the airfoil into an upper & lower surface Mean Camber Line - correct answer obtain a curve between the upper & lower surfaces Camber - correct answer maximum distance between the two lines, the measure of the curvature of the airfoil Thickness - correct answer maximum distance between the upper & lower surfaces Wingtips - correct answer the ends of the wings Wingspan - correct answer the distance from one wingtip to the other Platform - correct answer the shape of the wing viewed from above True or False? The left and right wings truly aren't horizontal, but instead meet at a dihedral angle. - correct answer True What three basic wing types are used on modern planes? - correct answer 1. straight 2. sweep 3. delta Straight Wing - correct answer found on small, low-speed airplanes, gliders and sailplanes. Give the most efficient lift at low speeds, not very good for high speed. Swept Wing - correct answer Most common design for modern high-speed airplanes. creates less drag from straight-wing, somewhat more unstable at low speeds. Fighter planes have wings with greater sweep, which do not generate much lift at low-speed and require high-speed takeoffs and landings.
