A controller passing the QNH always makes me (and all those I've flown with) look straight at the altimeter.....
It is a way of making a pilot actually look and see (and confirm by readback) that he really does have the correct setting
dialled in, rather than just having
copied the numbers.
That reminds me, really must get the altimeter converted to read those Euroland Hectopascals / Hectopasc-alls / Hectopaz-calls / Hector Pasquales (Joes brother?)
Rather than Millie Barrs, who apparently can't make altimeters work any more, although she did a perfectly good job for many, many years.
