Certified for Accuracy 2025/2026
The angle formed by the chord of an airfoil and the direction of the relative
wind is called - correct answer angle of attack
Aircraft structure consists of - correct answer fuselage, wings, empennage
(tail), landing gear, power plant
Empannage parts - correct answer fixed: vertical stabilizer and horizontal
stabilizer
Moveable: rudder, elevator, trim tabs
Power plant powers - correct answer engine and propeller
What does the cowling do - correct answer helps cool the engine
Propeller creates - correct answer thrust
What does the rudder do - correct answer yaws the aircraft
What does the elevator do - correct answer moves the aircraft nose up or
down
What is important about atmospheric pressure - correct answer weather
changes help lift airplane, actuates some flight instruments
, What does air density do - correct answer effects airplanes capabilities
Less dense air - correct answer reduces power, thrust and lift
Density increases with - correct answer altitude
Increases the temperature does what to the density - correct answer
decreases the density
Newtons laws of motion 1 - correct answer body as rest remains at rest
Newtons law of motion 2 - correct answer constant force creates
acceleration proportional to mass
Newtons law of motion 3 - correct answer for every action, there's an
equal and opposite reaction
Magnus effect - correct answer low pressure upward force
Axes of flight - correct answer pitch, roll, yaw
Pitch is - correct answer lateral axis (thru wings)
Roll - correct answer longitudinal axis (thru body)
Yaw - correct answer vertical axis (up and down)
