Aircraft braking systems include: Aircraft disc brakes in the landing gear, used to brake the wheels while touching the ground. These brakes are operated hydraulically, pneumatically or electrically. In most modern aircraft they are activated by the top section of the rudder pedals ("toe brakes"). In some older aircraft, the bottom section is ...
Virtually all jet-powered aircraft have an air brake or, in the case of most airliners, lift spoilers that also act as air brakes. Propeller-driven aircraft benefit from the natural braking effect of the propeller when engine power is reduced to idle, but jet engines have no similar braking effect, so jet-powered aircraft must use air brakes to ...
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.
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]
Most large aircraft also use power hydraulic wheel brakes, due to the immense amounts of braking force they can provide; the wheel brakes are linked to one or more of the aircraft's main hydraulic systems, with the addition of an accumulator to allow the aircraft to be braked even in the event of a hydraulic failure.
The runway was very wet on the first landing, and the aircraft's all up weight was at least 12 per cent above the maximum landing weight. The brakes were held on at approximately 1,200 lb/sq in pressure from a speed of 80-85 knots, until the aircraft came to rest. The braking distance was estimated at 1,200 yards. The tyres were completely ...
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
Proponents of the system point out that using BTV will reduce wear on brakes and tires (estimated at 20% reduction over present wear rates), less time that the aircraft spends within the active area of the runway, and enhanced ability to predict required cool-down time on the brakes (and thus to better control minimum gate turnaround time).
