Yep - 1mb is of course 1 hPa. .. .But I see GW's point!

Yet US pilots often read back a millibar setting in hectopascals! And when it's 1000mb why don't we say "QNH 1 bar"?

NorthernSky. .. .How did different languages contribute to the Streamline accident at CDG?. .. .I did suggest, through CHIRP, a procedure to avoid that type of accident, but SRG couldn't see the point - watch that space!

2 Sheds: Not addressed to me and I don't have the report to hand, but from what I remember, the MD80 was being addressed in French and the SSW crew were given a conditional line up without being aware that the MD80 had been cleared for take off. It was suggested that had ALL instructions been in English then increased situational awareness might have prevented the accident.
