FLIGHT
Important Terms - Speaking the Language of Flight
You will find throughout all of the cadet aerospace education volumes.

Think of these as a new "language." To fully understand the science and technology of
terms
aerospace, you must learn a new vocabulary. Then, when you are around airplanes, mechanics and
pilots, or when you're on an orientation flight, you will be able to "speak language." That is a

very rewarding part of the learning process
.
Important Terms - Learning The Language Of Airplanes
aero
-
pertaining to air
aerodynamics
-
relating to the forces of air in motion
aeronautics
-
the science of flight within the atmosphere
aerospace
-
a combination of and
 se
AGL
-
above ground level
air
-
a mixture of gases that contain approximately 79% nitrogen, 19% oxygen and 2% other
gases
aircraft
-
any machine that is capable of flying through the air. Ultralights, airplanes, gliders,
balloons, helicopters are all included
airplane
-
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, such as a jet or rocket
airfoil
-
component, such as a wing, that is specifically designed to produce lift, thrust or
directional stability
airport
-
a place on either land or water where aircraft can land and take off for flight
altitude
-
height expressed in units above sea level, or ground level
aviation
-
the art, science and technology of flight within the atmosphere
aviator
-a person who operates an aircraft during flight
camber
-the curved part of an airfoil that goes from the leading to the trailing edge
chord
-
a line drawn through an airfoil from its leading to its trailing edge
drag
-
a force which retards the forward movement of an aircraft in flight
dynamic
-
forces in motion
leading edge
-the front part of an airfoil
lift
-
the upward force, which opposes gravity, that supports the weight of an aircraft
relative wind
- the flow of air which moves opposite the flight path of an airplane
static
-
standing still, or without motion
supersonic
- faster than the speed of sound. Subsonic is below the speed of sound
thrust
- the force which moves an aircraft forward in flight
trailing edge
- the back part of an airfoil
