What part of the wing has the lowest pressure as it passes through the air?
Bottom
Top
Front
Back
What is the force that drives the aircraft forward?
Weight
Drag
Thrust
Lift
When forces are equal, the aircraft will:
Decelerate
Remain at constant velocity
Fall out of the sky
Accelerate
When angle of attack exceeds a limit, lift drastically decreases. This is called:
A stall
A turn
A spin
A vortex

Rudder
Aileron
Elevator
Fin
Which of these is used to pitch an aircraft?
Aileron
Rudder
Fin
Elevator
Pitch, yaw and roll are always described in relation to the:
Pilot
Horizon
Ground
Aircraft
As air passes over the top of the aerofoil, it will:

How are gliders launched?
Using the engines
Aerotow
Winch
Slingshot
What forces is missing on a glider?
Weight
Thrust
Drag
Lift
What is Newton's 3rd Law?
F = ma
A force is required to alter a body's state of motion
Every action has an equal and opposite reaction
An object's motion will remain constant unless acted upon by an unbalanced force
What is Newton's 2nd Law?
An object's motion will remain constant unless acted upon by an unbalanced force
F = ma
A force is required to alter a body's state of motion
Every action has an equal and opposite reaction
What causes lift?
The Venturi Effect
Bernoulli's Principle
Snell's Law
Archimedes' Principle
For an aircraft to climb, the stick must be pushed:
Forward
Left
Right
Back
When should a glider pilot use the airbrakes?
When launching
When landing
When climbing
When in the hangar
