Mr. Simmons asks you to explain Bernoulli’s principle. You respond to her by saying, “When air accelerates, (a) . When air decelerates, pressure (b) .”
Consider what you know about the three axes and airplane movement. Read the scenario, and then choose the best statement to describe your action, the aircraft's reaction, and the axis it’s acting on.
“All right, Cadet, I want you to yaw left. What will you do? What is the aircraft's reaction?
And what axis are you acting on?”(Select the best answer.)
Push stick left
elevator moves down
vertical axis
Push stick left
aileron lifts up
longitudnal axis
push rudder pedal left
rudder turns left
vertical axis
push stick back
rudder turns left
lateral axis
When air is heated at ground level, it rises in the form of a thermal capable of lifting a sailplane for hours because the air (a) as it rises.

The height or distance above a reference plane
The most common planes of reference used in aviation are:
heights above sea level and ground level
above average sea level, or mean sea level (MSL),
and above ground level (AGL).

Match the following:
Force
A push or pull on an object.
Lift
An upward force created by the flow of air over the wing.
Drag
The force of air resistance on a plane. It opposes thrust.
Thrust
The force that pushes a plane forwards. Created by the engine/propeller.
Weight
The downward force on the plane caused by gravity.
