'Back when' the A400M was still the 'FLA', I wound them up at Farnborough by saying that 'FLA' actually just stood for 'Funny Looking Albert'...
Whereas C-130J was J for 'Just another Herk' - or 'J for Joke' as it certainly was at the time when Lockheed Martin was having all the problems. Though it isn't nowadays, of course, as we all know.
The TPA400 needed beefing up in certain areas, I understand. But delivered the beans pretty well.
It must have a
very clever engine/prop computer to have a single lever idle-max, 0/0 to M0.72/FL370 range to sort out!
