All aircraft are built with the same basic design. These features are:
Wings or rotary blades for lift.
Engines or jet propellers.
A fuselage to carry the crew or fuel.
A tail assembly (empennage) to mount the control surface for flight configuration.
“WEFT” is a mnemonic the refers to the major features of any aircraft: Wings, Engines, Fuselage and a Tail.
These elements differ in shape, size, number, and position. The differences distinguish one aircraft type from another. The individual components can be taught as separate recognition and identification features, but it is the composite of these features that must be learned to recognize and identify an aircraft.
