초록

An APU has a control for controlling a load on the APU from an associated aircraft. The control further receives information with regard to a temperature challenge around the APU. If the temperature challenge exceeds a predetermined threshold, then the control operates the APU with a reduced load in a cool down cycle to reduce the heat load from the APU on an associated tail cone. A method is also disclosed.
