Fun for simple people...

...was watching to co-pilot trying to zero the altimeter at Embakasi, Kenya and wondering why it took so long.

Almost as much as watching the dawning realisation on the face of the junior nav that low pressure systems rotate the other way south of the equator and that we were now going the wrong way round the dying remnants of a cyclone.

The first words of Buys Ballots law should always be voiced "In the Northern Hemisphere....."

I always thought "in the Northern Hemishpere" was a standard part of BB's law - it was as I learned it - and my son who has qualified as a YM Ocean has learned it the same way.

You're right, Wander00...

.....but not everyone remembers to say it. Earlier this year on hols in Oz I tried
a little experiment with "nephew-in-law"?? who holds a CPL and asked him if he'd heard of BB's law. He had but when asked to repeat it just said "if the wind's in your back the low pressure is on the right - no?"

He then got slightly cross and accused me of pedantry and said "Well, WTF does it matter anyway!!"

The yoof of today - sighs - can't tell them anything.

Back to the thread...

I believe the standby altimeter on the VC10 goes down to at least 500mb, I'm sure Beagle will know for sure!

Our off-the-shelf altimeter on the S-3 goes down to 850mb.

Mid 70s, station exercise at Honington, 12 Sqn Buccs awaiting Strike Launch, "Crews to cockpits" called 3 hours previously and Foldie and his pilot feeling incredibly bored having exhausted the potential I Spy targets from the Eastern dispersals. Bucc fitted with pedestal altimeter between Nav's knees. OK man in front, How low do you think I can wind the QFE down to?

He never got close as there was a graunching crunch as the knob came off in my hand passing 948! Thankfully, we never launched and a very sheepish Foldie had to explain to the Line Hut crew just what he had done!! As ever a crate of beer resolved any issue!

I'm glad I never got that bored on Q Foldie. But of course, us Air Defenders used to go flying on QRA,
