Will they use QFE or QNH?
Yes. (sarcastic answer)
I thought, it's on the coast, surely it won't matter. I was surprised when looking it up to see that the aerodrome elevation is 390', 13millibars (or Hectopascals if you're being picky) so it matters quite a lot!
I guess the RAF are wedded to QFE for arrival but it's hardly a problem to adjust by adding 13 if you want QNH, I'd have thought...
Or, even, just use QFE! (or is that against the rules if your comany is wedded to QNH?)
