I am not sure about your definition of "in the vicinity". Heathrow have been using "reduced separation in the vicinity of an aerodrome" for years and since their ATZ would not extend much past the ends of the runways, does this mean that their operation has been illegal?????!!

I have been passed the RPS on a number of occasions by a unit not a million miles away from Middle Wallop as I was heading in the direction of the TMA, but I always ask for the QNH instead anyway.
Back to QFE for a second. It is worth bearing in mind that the EGPWS must be over-ridden for QFE operations on the Boeings that I fly. Just one of those little things that add to the workload when we conduct QFE operations.
