Observe maximum quick turnaround limit.
Table shows energy per brake added by a single stop with all brakes operating. Energy is assumed to be
equally distributed among the operating brakes. Total energy is the sum of residual energy plus energy
added.
Add 1.0 million foot pounds for each taxi mile.
For one brake deactivated, increase brake energy by 13 percent.
For two brakes deactivated, increase brake energy by 25 percent.
When in caution zone, wheel fuse plugs may melt. Delay takeoff and inspect after one hour. If overheat occurs
after takeoff, extend gear soon for at least 8 minutes.
When in fuse plug melt zone, clear runway immediately. Unless required, do not set parking brake. Do not
approach gear or attempt taxi for one hour. Tire, wheel and brake replacement may be required. If overheat
occurs after takeoff, extend gear soon for at least 12 minutes.
Brake temperature indication on Multifunction Display may be used 10 to 15 minutes after airplane has come
to a complete stop, or inflight with gear retracted, to determine recommended cooling schedule.
