In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. [1] When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. [2]
In some older aircraft, the bottom section is used instead ("heel brakes"). Levers are used in a few aircraft. Most aircraft are capable of differential braking. [1] Thrust reversers, that allow thrust from the engines to be used to slow the aircraft. Air brakes, dedicated flight control surfaces that work by increasing drag.
Air brake may refer to: Air brake (aeronautics), a type of flight control system used on aircraft to reduce speed; On ground vehicles, (more formally, specified as) compressed-air-actuated braking systems: Air brake (road vehicle), friction-mediated type of brake used on large road vehicles in place of hydraulic brakes
Aerodynamic braking is a common braking technique during landing, which can also help to protect the wheel brakes and tires from excess wear, or from locking up and sending the craft sliding out of control. It is often used by private pilots, commercial planes, fighter aircraft, and was used by the Space Shuttles during landings. [21] [22] [23]
Air brakes are used to increase drag. Spoilers might act as air brakes, but are not pure air brakes as they also function as lift-dumpers or in some cases as roll control surfaces. Air brakes are usually surfaces that deflect outwards from the fuselage (in most cases symmetrically on opposing sides) into the airstream in order to increase form ...
An autobrake is a type of automatic wheel-based hydraulic brake system for advanced airplanes. [1] The autobrake is normally enabled during takeoff and landing procedures, when the aircraft's longitudinal deceleration system can be handled by the automated systems of the aircraft itself in order to keep the pilot free to perform other tasks.
British Airways Flight 216 reached a top speed of 809 mph Sunday and landed at London Heathrow 20 minutes early after departing its gate at 6:38 p.m., FlightAware data shows.
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.
