APU

Aircraft ground power

APU stands for auxiliary power unit—a small engine on aircraft that provides electrical power and air conditioning while the main engines are off, typically during ground operations.

APUs allow cabin systems to run without relying on external ground power.

In computing, APU refers to an accelerated processing unit, a chip combining CPU and GPU functions on a single die.
