GWH Correct
I was only generalising. RPS it is: Barnsley Holyhead etc
And of course being the lowest forecast for the period anyone flying on that instead of a local QNH will always be higher/ safer where terrain is concerned - but of course nearer to anyone overflying them, on the local QNH (or in the case of the mil within a MATZ- QFE), at what appears initially to be a safe alt above.
I cant remember what the mil or civs put into their radars,(1013 maybe as a standard ref) Im sure someone will soon tell. But I do know that when trying to coordinate arrivals and deps with LARS traffic, quick, accurate mental arithmatic was part and parcel of the daily tasks in order to work out whether you had the 500 or 1000' needed. Indeed as an RAF Instructor I often found that the pressure questions in an ATC groundschool phase were always a good test of the speed of a students processor so to speak. Often those that struggled to add or subtract correctly under a modicum of time pressure werent so good in the sim.
