Dive brake

The dive brakes on this SBD Dauntless are the slotted panels visible under the wings.

Dive brakes or dive flaps are deployed to slow down an aircraft when in a dive. They often consist of a metal flap that is lowered against the air flow, thus creating drag and reducing dive speed.^[1]

In the past dive brakes were mostly used on dive bombers, which needed to dive very steeply, but not exceed their red line speed in order to drop their bombs accurately. The airbrakes or spoilers fitted to gliders often function both as landing aids and to keep the aircraft's speed below its maximum permissible indicated air speed in a vertical dive. Most modern combat aircraft are equipped with air brakes, which perform the same function as dive brakes.^[1]^[2]
