Where do you work/fly? Nats at least uses Hp, been mandated for a few months now
It's a fair cop, I haven't been flying for some time and my information is out of date
- it was correct when HPa was introduced and I hadn't realised it had changed. Sorry!
(Although reading the latest CAP413 I can't find any reference to the change except to that of changing the words in the document itself - no mention of the removal of the difference).
I note that Hectopascals are now only said when the number is less than 1000, presumably because that's when it could be confused with inHg.
