Dive

 

the movement of an aircraft or missile along a horizontally inclined trajectory of 30°-90°, accompanied by rapid loss of altitude and an increase in speed.

The flight trajectory during a dive consists of the leg of the dive proper, which is close to a straight line, and of curvilinear legs—the initial (entrance) and final (pullout) legs. A dive at angles of 80°-90° to the horizontal is called a vertical dive. Air brakes are used on aircraft and missiles to limit the increase in speed. Diving is used during attacks on aerial targets, during firing or the launching of rockets, and during the bombing of ground or naval targets. Diving is also used when it is necessary to lose altitude quickly. [19—1571—4•]
