Generally the RAF use MPH, the RN use Knots and the Army use Leagues (per hour) (
)
The Joint Force Harriers had a button to recalibrate all the flight instruments when changing from RAF to RN pilots (or vice versa - nother Joke there but won't push it)
Luckily the practice of recruiting army helo pilots for Harriers had died out by then as the 2-bit DACs in the instruments couldn't handle tri-state conversion...
Seriously, for the Apache you would assume MPH for corresopondence with ground vehicles...assuming the ground vehicles don't use KPH for correspondence with european armies?

And yes, would REALLY like a UK Apache in CH, then I could retire Gunship!
Anybody read
'Dressed to Kill'?
Not a button-pushers book but very interesting so far.
