Where does the auxiliary heat air exit in the aircraft?

The auxiliary heat air typically exits the aircraft through the foot panels. This system is designed to provide additional heating to the cabin, especially useful in cold weather conditions during flight or ground operations. By directing the warm air towards the foot area, passengers and crew can maintain a comfortable temperature, which is important for overall comfort and safety.

In aircraft, different exit locations may cater to various functions, such as overhead panels directing air towards the head and shoulders, side vents adjusting airflow for personal preferences, or ceiling ducts aiding in overall cabin circulation. However, auxiliary heating specifically emphasizes warming the lower part of the cabin, hence the exit being strategically located at the foot panels.
