NAVY AVIATION MACHINIST COMPREHENSIVE EXAM
QUESTIONS AND ANSWERS 2025/2026 ALL RATED A+
✔✔Rudders - ✔✔Connected to the trailing edge of the vertical stabilizer, and are used
to move the nose of the plane to the left or right, typically in combination with the
ailerons
✔✔Trim Tabs - ✔✔Movable surfaces that extend off the trailing edges of the rudder,
elevators, and ailerons, and are used to make smaller adjustments
✔✔Landing Gear - ✔✔Consists of three sets of wheels used for takeoffs and landings,
commonly retractable, meaning that it is pulled up inside the plane during flight to
reduce drag
✔✔Wheel Sets - ✔✔Positioned either under each wing or on the sides of the fuselage,
with the third wheel set being under the nose or the tail
✔✔Tricycle Arrangement - ✔✔The third wheel set under the nose, is the most common
arrangement on modern aircraft
✔✔Conventional Arrangement - ✔✔Having a third wheel set under the tail
✔✔Powerplant - ✔✔The part of the plane that supplies the thrust, a jet engine operates
by compressing the air that comes in the front, burning it along with fuel, and then
blasting it out the back
✔✔Afterburners - ✔✔Feed extra fuel into the area between the turbines and the rear
exhaust, increasing forward thrust
✔✔Propeller Plane - ✔✔The powerplant is the propellers and the engine, the propellers
have tilted blades, which push air backwards and thereby push the plane forward
✔✔Two types of propeller - ✔✔The blade angle of a fixed-pitch propeller cannot be
adjusted by the pilot. Variable-pitch propellers allow the pilot, usually indirectly via the
plane's control systems, to adjust the pitch of the propeller blades to alter the amount of
thrust being generated
✔✔Constant-speed propellers - ✔✔Some variable-pitch propellers are designed to
operate only at a single rotational speed, allowing the engine to be much simpler and
more efficient, so the amount of thrust is controlled entirely by the pitch of the blades
✔✔Single-engine planes - ✔✔Engines are typically in front of the fuselage
