Section Exam Questions and Answers
100% Pass
A Helicopter - ✔✔Is a type of rotorcraft that is able to takeoff and land vertically,
hover, and fly forward, backward, and side to side (laterally).
Thrust engine - ✔✔an engine that produces power and delivers it to overhead and tail
rotors (on most helicopters) via one or more transmissions and drive shafts.
Fuselage - ✔✔Main Body of the helicopter
Mast - ✔✔Shaft protruding from the top
Cowling - ✔✔On the upper part of the fuselage of many helicopters, it covers the
aircrafts engine and transmission.
two and six rotor blade - ✔✔How many rotor blades are attached to the mast via a rotor
head?
Flybar - ✔✔also called a stabilizer bar.
upper and lower swashplates, blade grips, control rods, pitch and scissor links, teeter or
coning hinges, pitch horns, and counterweights - ✔✔Rotor systems consist of what
components?

, enhance flight stability by keeping the bar stable as the rotor spins, and to reduce
crosswind thrust on the blades - ✔✔What is the Flybars Function?
cyclic collective, throttle and pedals - ✔✔what are the pilot's flight instruments and
controls?
Avionics - ✔✔what are electronics used for navigation, communications and aircraft
systems term?
Weapons controls - ✔✔What are the weapons called in military helicopters cockpit
Fire extinguisher, flashlight - ✔✔what are the other equipment in the cockpit?
weight, lift, thrust, and drag - ✔✔what are the four aerodynamic forces that act on a
helicopter when it is airborne?
Lift - ✔✔what is the force that counteracts an aircrafts weight and causes a helicopter to
rise into the air and stay aloft.
Lift - ✔✔is produced by airfoils - rotor blades, in the case of helicopters - that move
through the air at a speed sufficient to create a pressure differential between the two
sides of the airfoils.
Thrust - ✔✔is an aircraft's forward force, which is created by one or more engines, and
is transformed in the case of helicopters into rotary motion via the components
mentioned. Generally, thrust acts parallel to the aircrafts longitudinal axis, but not
always.
Drag - ✔✔opposes thrust; it is a rearward- acting force caused by airflow passing over
the aircraft's structure and becoming disrupted. Drag acts parallel to the relative wind.
Profile, induced and parasite - ✔✔what are the three types of drag?
