The APU will power critical functions like cockpit displays and radios, as well as passenger comforts like air conditioning, heating, lights, and galley equipment.
Especially if we really are a couple of years away from the next generation of consoles, it's very easy to imagine a full eight-core Ryzen CPU set up inside a console APU.
An APU is a small turbine engine that, on modern jets, is attached to the rear fuselage of the aircraft to provide power onboard when the main engines are switched off.
By utilizing the APU bleed air for an engine start, it allows pilots to select the best lift to drag ratio speed to extend the glide range during engine re-start attempts.
