Airbus recently published the following video showing APU and engine start-up of the first Airbus A400M. The Airbus A400M is a European four-engine turboprop military transport aircraft that can be configured for aerial refueling. It has been designed by Airbus Military corporation to replace a variety of aircraft, including the Lockheed Martin C-130 Hercules and the Transall C-160.
I visited factory where is A400M produced two weeks ago. It is in Sevilla in Spain. I saw the airplane on my own eyes.
