APU : Auxiliary power Unit
Used for Electricity generation and conditioning air .
Most generally, an APU exhaust is located in the rear of an aircraft
In the 737, the APU is a turbine, which is induced by air when fying
When rotating, the turbine related to a bobine produces electrical
energy
It is very important to have an APU "ON" when altitude increases
