Exam Questions and CORRECT Answers
What is included in the attitude of the aircraft? - CORRECT ANSWER - Pitch and bank
Pitch - CORRECT ANSWER - Is the nose up or down attitude of the plane in relation to
the horizon
Bank (or Roll) - CORRECT ANSWER - Is the relationship of the line drawn from wingtip
to wingtip on the horizon
Isaac Newton's three laws of motion detail what fundamentals of flight? - CORRECT
ANSWER - Mechanics of motion
Law of Inertia (1st Law of Motion) - CORRECT ANSWER - An object will stay at rest
and an object in motion will remain in motion at a constant velocity unless acted upon by an
unbalanced force. The unbalanced force may be any force such as gravity or friction
Identify the four types of frictions which correlate to Newton's 1st Law of Motion - CORRECT
ANSWER - Sliding (Kinetic), Fluid, Rolling, and Static
Fluid Friction - CORRECT ANSWER - Resistance on an object when it is moved through
either air (gas) or water (liquid)
Rolling Friction - CORRECT ANSWER - Occurs when an object rolls (instead of slides)
across a surface
Static Friction - CORRECT ANSWER - is what keeps an object at rest when that object is
acted upon by an external force
,Kinetic (sliding) Friction - CORRECT ANSWER - Results when the surface of one object
slides along the surface of another object
Newton's 2nd Law of Motion - CORRECT ANSWER - Acceleration of an object depends
on the mass of the object and the amount of force applied
Newton's 3rd Law of Motion - CORRECT ANSWER - For every action, there is an equal
and opposite reaction. Example - when a bird flies, their wings exert a downward force on the
air, as a result, the air also applies an equal and opposite force which pushes the bird upwards.
Newton's Law of Universal Gravitation - CORRECT ANSWER - States that a particle
attracts every other particle in the universe with a force that is directly proportional to the
product of their masses and inversely proportional to the square of the distance between them.
(Gravity gets weaker with distance)
Bernoulli's Principle - CORRECT ANSWER - In relation to hydrodynamics - within a
horizontal flow of fluid, points of faster fluid speed will experience less pressure than points of
slower fluid speed. In relation to flight - the curvature of an airplane wing causes air to pass
faster over the top of the wing (creating a lower pressure area) than under the wing (a higher
pressure area) - this creates lift.
What are the four forces of flight? - CORRECT ANSWER - Weight, lift, thrust, and drag
MEW- Manufacturer's Empty Weight - CORRECT ANSWER - Total weight of the aircraft
as it was built
OEW - Operating Empty Weight - CORRECT ANSWER - OEW is the MEW + weight of
the crew, fluids, unusable fuel, and the equipment required for flight. DOES NOT include
baggage, passengers, or usable fuel.
AUW (AGW) - All up weight or Aircraft Gross Weight (AGW) - CORRECT ANSWER -
The total aircraft weight at any given moment during a flight. ***The AUW decreases as fuel
and fluids are consumed during the operation of the flight
, Maximum Landing Weight (MLW) - CORRECT ANSWER - Aircraft's weight limit for
landing
Maximum Zero Fuel Weight (MZFW) - CORRECT ANSWER - The permissible weight of
an aircraft with its contents and includes unusable fuel. (EXCLUDE the weight of consumable
fluids)
Maximum Takeoff Weight (MTOW) - CORRECT ANSWER - Weight Limit for takeoff
(exceeding this limit increases the power required for takeoff, lengthens the runway distance
needed for a successful lift off and places excess stress on the aircraft's structure)
What is MRW? ( - CORRECT ANSWER - Maximum Ramp Weight - Weight Limit for an
aircraft to be towed or taxied
Flight Envelope - CORRECT ANSWER - Encompasses the limits of speed, altitude, and
angle of attack required by any aircraft to maintain a stable flight. ***Failure to follow the flight
envelope may result in a stall.
Angle of Attack (AOA) - CORRECT ANSWER - Angle between the direction of the
airflow against the wing and the CHORD. pg. 144
What are the two control parts of a trailing edge of a wing? - CORRECT ANSWER -
Ailerons and flaps
Where are the Ailerons located? - CORRECT ANSWER - From the midpoint of the
trailing edge of the wing to the wing's tip - they control the lateral movement of the aircraft
Where are the flaps located? - CORRECT ANSWER - From the fuselage to the midpoint
of the wing - they change the lift characteristics of the aircraft
