I have no problems with using whatever the controller wants me to use. I was just highlighting that the practice of using QFE throughout the MATZ is not in compliance with what is written in MATS Part 1, which perhaps explains why those users who know and understand the requirements are expecting it to be QNH.
Incidentally what happens when the MATZ controller does not answer? So I'm flying happily through the Wallop/Boscombe CMATZ making blind calls. What am I supposed to set my altimeter to? What for that matter is a Mil a/c doing the same thing going to set his altimeter to? Common sense suggests the RPS.
And the club aircraft operating out of Boscombe? Presumably they're flying outside their ATZ with QFE still set if that's the Mil practice while Old Sarum, which is a licensed a/d within the CMATZ are using their QFE within their ATZ and QNH outside it.
It's all part of the wonderful joined up safety-conscious aviation world.
As PPRR says, it's a non-issue.
