BP = blood pressure 
I have no idea what this is supposed to mean I guess it’s like English sports:
It’s called the ‘inverse moustache-and-goggles coefficient of pompousness’ 
and you’re quite right, Peter!
What do you mean by “BP requirement” and “200/150” ??
Never heard of these.
I wondered about this, having just been to the Scilly Isles EGHE for a few days. I reckon the ATCO was at least 200/150, yet the population is about 2300.
It can be similar at Alderney EGJA which is around 1800…
Do these places get loads of accidents?
