Lets add one more myth....QFE altimeter settings are more accurate than QNH
--------------------------------------------------------------------------------
If it's an airfield QNH, then there should be no difference in accuracy, but a regional QNH is a forecast figure, so only as accurate as the Metman.

And of course the accuracy of the altimeter is (presumably) optimised for "normal" figures. So using QFE at Nairobi (if you could dial it up) probably wouldn't be terribly accurate. - Just guessing on the latter point though...
