Douglas SBD Dauntless dropping a bomb, circa in 1942

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.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 168. Aviation Supplies & Academics, 1997. In the past, dive brakes were mostly used on
