ADVISORY INFORMATION
Recommended Brake Cooling Schedule
Adjusted Brake Energy Per Brake (Millions of Foot Pounds)
Two Engine Detent Reverse Thrust
Cooling Time (Minutes) - Category A Brakes
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.
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 7 minutes.
When in fuse plug melt zone, clear runway immediately. Unless required, do not set parking brake. Do not
approach gear or attempt to 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 Indicator (if installed) on First Officer’s Instrument Panel may be used 10 to 15 minutes
after brake application, to determine recommended cooling time.
