Billy Mitchell Aerospace Test questions
and answers
Aerospace Education - answer-Branch of general education concerned with
communicating knowledge, skills and attitudes about aerospace activities and the
total impact of air and space vehicles upon society
Airport - answer-Place on either land or water where aircraft can land and take off
for flight
AGL - answer-Above Ground Level
Aerospace - answer-A combination of aeronautics and space
Aviation - answer-The art, science and technology of flight within the atmosphere
Aviatior - answer-Person who operates an aircraft during flight
Supersonic - answer-Faster than the speed of sound
Subsonic - answer-Slower than the speed of sound
Aero - answer-Pertaining to air
Airplane - answer-An aircraft that is kept aloft by the aerodynamic forces upon its
wings and is thrust forward by a propeller or other means of propulsion
Static - answer-Standing still/ non-moving
Airfoil - answer-A component, such as a wing, that is specifically designed to
produce lift, thrust, or directional stability
Airfoil Components - answer-Leading edge, trailing edge, chord, camber
,Aircraft - answer-Any machine capable of flying through the air
Air - answer-79% Nitrogen, 19% Oxygen, 2% other
Aerodynamics - answer-Relating to the force of air in motion
Aeronautics - answer-The science of flight within the atmospehere
Mongolfier Brothers - answer-French brothers who created the first manned hot
air balloon in 1783
Dynamic Lift - answer-Newton's Lift, takes effect when a bird changes its body
angle slightly upward to it's flight path
Induced Lift - answer-Bernoullian Lift, pressure difference between upper and
lower areas of a bird's wing
Dynamic - answer-Force in motion
Daniel Bernoulli - answer-Discoverer of relationship between pressure and fluids
in motion
Bernoulli's Principle - answer-When a fluid accelerates, the pressure drops
Newton's 1st Law - answer-An object at rest remains at rest unless acted upon
by an outside force
Newton's 2nd Law - answer-A force acting upon a body causes it to accelerate in
the direction of the force; acceleration is directly proportional to the mass of the
body being accelerated
Newton's 3rd Law - answer-For every action, there is an equal and opposite
reaction
Trailing Edge - answer-The back portion of an airfoil
,Coefficient of Lift Formula - answer-Mathematical formula with 5 components: air
density, velocity, wing area, airfoil design, angle of attack
Camber - answer-Curved part of the airfoil that goes from the leading edge to the
trailing edge
Leading Edge - answer-The front portion of an airfoil
Relative Wind - answer-The flow of air which moves opposite the flight path of an
airplane
Natural Forces of Flight - answer-Drag and Gravity
Forces of Flight - answer-Lift, Thrust, Weight (Gravity), Drag
Thrust - answer-Moves an aircraft forward
Drag - answer-Force that retards forward movement of the aircraft
Chord - answer-Imaginary Line drawn from the leading edge to the trailing edge
of an airfoil
Lift - answer-Upward force that opposes gravity
Angle of Attack - answer-Angle between the chord line and the relative wind
Critical Angle of Attack - answer-The point at which a wing will stall
Stall - answer-Airflow breakaway from the surface of the wing creates a loss of
lift, occurs with an angle of attack around 17°
Pitch - answer-Rotation around lateral axes of an airplane
Yaw - answer-Rotation around vertical axis
Roll - answer-Rotation around the longitudinal axis
, Ailerons - answer-Surfaces on the ends of wings-when one moves up, the other
moves down. Ailerons control roll
Elevator - answer-Surface on the horizontal stabilizer of an aircraft. Changes
pitch.
Rudder - answer-Surface on the vertical stabilizer of an aircraft. Moves the
aircraft right or left (yaw)
Flaps - answer-Surfaces on the wings used to generate lift
True or False: A propeller creates lift - answer-True
Function of a Tow Plane - answer-To tow a glider behind it on a cable and
release it at an appropriate altitude
Aspect Ratio - answer-Ratio between wingspan and chord length
Wingspan - answer-Distance from wingtip to wingtip
Convection - answer-Fluid motion between regions of unequal heating
Average Lapse Rate - answer-5.3°F per 1000 ft altitude increase
First Manned Flight - answer-Paris: November 21, 1783 (Mongolfier Brothers in
their hot air balloon)
Envelope - answer-Main body of a hot air balloon
Gore - answer-One of the several vertical panels making an envelope
Thermistor - answer-Instrument that measures temperature in the envelope of a
hot air balloon
Hot Air Balloon Instruments - answer-Altimeter, vertical velocity indicator,
thermistor
