Essential AFOQT Test Toolkit Questions with
Approved Credible Solutions 2025/2026
Biplane - correct answer an airplane with two pairs of wings
Thickness - correct answer a percentage of the wing chord; typically
ranges from 6.5 to 13.5 percent
Camber Line - correct answer amount of curvature of the wing. Imaginary
line runs halfway between upper and lower surfaces of the wing.
Chord - correct answer the imaginary line in an airfoil; establishes a
baseline for the amount of camber and width required of the wing along
with its wingspan
How many types of wing platforms are there? - correct answer 4
(rectangular, elliptical, tapered, and swept)
Rectangular wing planform - correct answer the simplest type, highly
inefficient, and typically used for light general aviation
Elliptical wing planform - correct answer the most efficient style, with the
lowest possible induced drag
Tapered wing planform - correct answer cross between a rectangular and
an elliptical, providing better lift distribution and moderate efficiency. Aircraft
with these wings have a wide range of speeds
,Swept wing planform - correct answer tapered back to reduce drag.
Includes slightly swept, moderately swept, and sharply swept types.
Disadvantages: tendency to twist under stress
The amount of lift generated is dependent on the difference between the
camber line and the _________ - correct answer chord line (when the
measurements of the chord line and camber line differ greatly, the
curvature of the wing will provide more lift)
Powerplant - correct answer encompasses the engines and propellers as
well as the induction, exhaust, electrical, cooling, lubrication, and fuel
systems
Reciprocating engine - correct answer An engine that converts heat
energy created by combusted fuel mixed with air into reciprocating piston
movement, which in turn is converted into a rotary motion via a crankshaft.
(typically aircraft with cruising speed not exceeding 250 mph)
Gas turbine engine - correct answer Engine that burns natural gas,
sending a hot, high-pressure stream of gas through a turbine connected to
an electrical generator. (larger more powerful planes)
Turbo-supercharged reciprocating engine - correct answer aircraft
traveling at high altitudes (over 30,000 ft)
Turbojet engine - correct answer A turbine engine which produces its
thrust entirely by accelerating the air through the engine. (those that
operate at Mach 1 or higher)
,During takeoff, engines operate at ________ - correct answer maximum
performance
Fixed pitch propeller - correct answer pitch has a blade angle that can't be
changed by the pilot. The propeller is connected directly to the engine's
crankshaft; engine power rotates the crankshaft as well as the propeller,
and the propeller converts the engine's rotary power into thrust
Variable pitch propeller - correct answer Allows the pilot to adjust the
blade pitch during flight
Pusher propeller - correct answer installed on the rear of an aircraft and
faces to the rear; the thrust created from its rotation pushes on the rear of
an aircraft instead of pulls the aircraft, contrary to fixed and variable
The pitch of any styles of propeller affects _______ - correct answer the
way it cuts through the air, producing air mass
Thrust Horsepower Equation - correct answer thp=(thrust x aircraft speed
(in mph))/375 pph
Styles of landing gear - correct answer tail wheel, tandem, tricycle
Tail wheel - correct answer landing gear consisting of a third wheel
assembly, beneficial for landing on non-paved runways (when aircraft's
main landing gear is positioned forward of its center of gravity)
Tandem landing gear - correct answer has both main and tail portions
mounted along the longitudinal axis of the aircraft. Supports the use of
flexible wings
, Tricycle landing gear - correct answer includes a main gear and a nose
gear, which together support increased braking ability, higher landing
speeds, and better visibility for ground operations
Tail (empennage) - correct answer rear portion of the aircraft; provides
stability and consists of the rudder, vertical stabilizer, horizontal stabilizer,
the trim tabs, and 2 elevators
Vertical tail structure consists of _____ - correct answer rudder and
vertical stabilizer
Rudder - correct answer used to keep the aircraft in coordinated flight; at
the rear end of the vertical stabilizer
Vertical Stabilizer - correct answer To control yaw.
Horizontal tail structure consists of _____ - correct answer horizontal
stabilizer and elevators
Horizontal stabilizer - correct answer at the front end of the tail structure;
prevents the aircraft from pitching up and down
Elevators - correct answer part on a plane's tail that makes the plane go
up and down; hinged to the horizontal stabilizer
Trim tabs - correct answer on the trailing edges of the wings toward the
fuselage, the rudder, and the elevators. Act as a secondary flight control
