UPDATED ACTUAL Exam Questions and
CORRECT Answers
A Helicopter - CORRECT ANSWER - 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 - CORRECT ANSWER - 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 - CORRECT ANSWER - Main Body of the helicopter
Mast - CORRECT ANSWER - Shaft protruding from the top
Cowling - CORRECT ANSWER - On the upper part of the fuselage of many helicopters,
it covers the aircrafts engine and transmission.
two and six rotor blade - CORRECT ANSWER - How many rotor blades are attached to
the mast via a rotor head?
Flybar - CORRECT ANSWER - 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 - CORRECT ANSWER - 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 - CORRECT ANSWER - What is the Flybars Function?
, cyclic collective, throttle and pedals - CORRECT ANSWER - what are the pilot's flight
instruments and controls?
Avionics - CORRECT ANSWER - what are electronics used for navigation,
communications and aircraft systems term?
Weapons controls - CORRECT ANSWER - What are the weapons called in military
helicopters cockpit
Fire extinguisher, flashlight - CORRECT ANSWER - what are the other equipment in the
cockpit?
weight, lift, thrust, and drag - CORRECT ANSWER - what are the four aerodynamic
forces that act on a helicopter when it is airborne?
Lift - CORRECT ANSWER - what is the force that counteracts an aircrafts weight and
causes a helicopter to rise into the air and stay aloft.
Lift - CORRECT ANSWER - 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 - CORRECT ANSWER - 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 - CORRECT ANSWER - 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 - CORRECT ANSWER - what are the three types of drag?
