Welcome! Hectopascal
It must have taken some late nights, but the CAA have today issued a statement that as of November this year in the UK we must all drop "millibars" and instead use "hectopascals". All METARS & TAFS & RT will have to comply.
When I first encountered hectopascal in was in Eire. And the controllers there make it sound like Hector Pascal. So maybe we should have a Hector Pascal Day to celebrate a complete waste of time.
The figures don't change one digit - just the description.
Aren't there more pressing issues for the CAA to sort out in our industry? Or have they really just become a toy remotely controlled from Euroland?
