Jumbo Driver - am with you on this one - I would vote to get rid of the RPS. Trouble is the military seem to like using it to use to compute such things as Minimum Height to Commence Recovery (from Spinning, for example) although, if my memory serves me correctly this is based on the Transition Level which, at most UK military aerodromes, is based on (you've guessed it!) the RPS.
Mind you whilst we are about it we could bin the QFE too - how much simpler life would be if it was just an aerodrome QNH!
