How will the maintenance organisations cope with all the required re-calibration of altimeters? Ours only show millibars and inches Hg.

Not sure why this thread is playing silly b's with the post timings...
But will the use of conversion tables will be acceptable?

If they did it every year (as strongly advised by the Guild of Retired RAF Navigators) they would know that there are 1.24 hectopascals per millibar.
I am sure Bob Pooley will be doing a special slide rule for doing the conversion.

IO...
As you obviously see yourself as an aviation expert ... do you have any idea what those funny little symbols, at the top of my aviation related posts on this subject, mean?

1 Hecto Pacscal (HPa) is indeed 1millibar since 1 Bar is equal to 1x10^5 Pascals.
so 1013mb for example is the same pressure value as 1013HPa
The only change will be the RT requirement to read back pressure settings less than 1000 in terms of HPa instead of millibar.

He used to make very nice sweets. 
When I was young and less jaded than I am now, I was sent to work on an aircraft carrier for a while. Every met brief the RN briefed QNH in hPa, which was fine - but it took me a week to work out why they never briefed QFE.
Answers on a postcard please.

ahh at last, I think I can help there. Hector was the dog in the TV program with ZaZa the cat and KiKi the frog.. Not sure of the connection to atmospheric pressure though.

Clearly it is at least a couple of years since ST and CA did their JAA ATPL Met Theory If they did it every year (as strongly advised by the Guild of Retired RAF Navigators) they would know that there are 1.24 hectopascals per millibar
...........Ok I get that this MUST be a joke, but im totally failing to locate the bit with the humour in it????????

Lone, Glad you posted that.
I thought "Is it me, or what?"
