Glossary
aircraft physics
Drag The resistance of air against moving objects.
Glide Slope The descent path along which an aircraft comes in to land.
Lift The force generated by an airfoil at a 90-degree angle to the airstream flowing past it.
Pitch The movement of an aircraft around an imaginary line extending from wingtip to wingtip, that results in the tail moving up and down. Pitch is controlled by elevators on the airplane.
Reverse Pitch A set of an airplane's propeller blades exerting a backward thrust to slow an aircraft after landing.
Reverse Thrust The effect caused by deflecting jet exhaust forward to produce a rearward thrust that slows an aircraft after it lands.
Roll The movement of an airplane around the imaginary line that runs down the center of the aircraft from nose to tail. The tilting, sideways motion is controlled by the ailerons.
Thrust The force generated by propellers or a jet engine flow that propels a plane through the air.
Yaw The swiveling movement to right and left that can be controlled by the rudder on the tail fin.
