Autobrakes
The autobrake system senses deceleration
and modulates the brake pressure required
accordingly. Early and effective application
of spoilers and reverse thrust is therefore very
important to minimize brake temperature
and wear.
If only minimum reverse thrust is used, the
brake energy required to stop the aircraft
almost doubles.
Brakes
The brakes slow down the aircraft by
absorbing the motion energy of the aircraft.
The brakes convert this motion energy into
heat, which is dissipated through cooling.
The brakes are required to absorb vast
amounts of energy. The higher the speed is
at the time the brakes are applied, the
higher the amount of energy they have to
absorb.
While reverse thrust is more effective at
higher airspeeds, the brakes are more
effective at lower airspeeds.
During a normal landing, as speed is being
reduced, the brakes should be applied just
prior to the termination of reverse thrust
operation. This practice will result in the most
economical landing performance.
