HEATING - DESCRIPTION AND OPERATION
___________________________________
1. General
_______
A. Aft Cargo-Compartment Heating Ventilation air which comes from the cabin zones (Ref. 21-28-00) is mixed with hot bleed-air from the APU bleed-air duct and is sent to the AFT cargo compartment. This raises the temperature in the compartment to a preselected level.
