I'm not quite clear which subject it is you find surprising ... ? If it is my original question (i.e. the topic of this thread), it was after some consideration that I posed the question on this forum because I felt it was likely to prompt more erudite and informed answers (perhaps) than elsewhere.

My question was - and still is - not how we should use RPS but whether we still use and need it.

As a regular flier from a private site, I am perfectly happy, knowing the elevation of the strip, to wind that altitude on the altimeter, thus providing my own "derived" local QNH. I don't think there is any doubt on this forum that, for any foray under CAS where the base is expressed as an altitude, an appropriate aerodrome QNH should be used.

... or perhaps I have misunderstood your post ... ?
