dive brakes

Control surfaces that extend from the aircraft surface and significantly increase drag, thus permitting aircraft to dive steeply at moderate air speeds. Dive brakes also are used to decelerate aircraft in flight. Spoilers may also function as dive brakes. Also called airbrakes

dive flaps

Surfaces on either the wings or the fuselage that can be extended in flight to create sufficient parasite drag to prevent aircraft from accelerating to very high speeds in a dive. The same as airbrakes and dive brakes.

speed brakes

A type of secondary aircraft controls, which increases the drag considerably when extended, permitting aircraft to decelerate or descend steeply. These are flat platelike structures on the top and/or bottom of the wings or the bottom or side of the fuselage, which remain flush in normal flight and are extended when in use. Also called dive brakes and airbrakes
