MAINTENANCE MANUAL

 D.  A high energy stop condition can be a refused takeoff. It can also be a stop or sequence of stops that collects energy in the CAUTION or FUSE PLUG MELT range (Fig 201). An indication that a high energy stop, or equivalent, has been made is the release of a wheel fuse plug. Energy levels are different between brakes after stops in the COOLING RECOMMENDED RANGE. One or more brakes could have absorbed energy in the CAUTION range, and one or more wheel fuse plugs released.
