‡ 6SDQ DOVR ³:LQJVSDQ´
The widest straight-line distance between the two wingtips.
‡ Speed Brakes
Large panels that fold out of the aircraft structure to provide a lot of extra drag to the air. They are not part
of the wing structure, but are usually mounted on the fuselage. Military jets most often have speed brakes,
which fold out of the fuselage. Some airliners use spoilers as speed brakes when at altitude.
‡ Speed Flap
The middle control surface on a 6-trailing-edge-surface glider or the inboard control surface on a 4-surface
glider.
‡ Spin
A maneuver where at least one wing is stalled and the two wings are operating at very different angles of
attack. This causes the airplane to rotate around its middle while it descends at a high rate of speed. When

control during the landing approach.
