St Mawgan & Plenty - sorry, all the times I've operated into there those two words just don't go together.
Bit like Finningley will be then...not many ATMs but plenty FJ traffic around them.
But it seems we're not talking about RAF ATCOs providing a service to Finningley traffic anyway so the comparisons are hypothetical, just a response to royman's idea of Waddo providing the service instead of ctrlrs at EGGP.
As to Inverness, fair point, they don't actually have an 'Inverness Approach' facility at Lossiemouth, but it's mandatory for IFR tfc to contact Lossiemouth (advisory for VFR).
