Just studying PPL Met on this beautifully dreary day and trying to work out whether both Zero and 360 degrees equate to North. The OAT Met CD Rom seems to indicate this but I just wanted to be absolutely sure as it isn't entirely clear.
Many thanks
Greg

It can be , if your referring to the winds given on tafs an metars then they are always 3 figures . I cant recall ever having seen north referred to as 000
I think and I stand to be corrected that it is normal to refer to it as 360 .
You certainly wouldnt be told by atc or other to turn heading 000 it would always be 360.
Cant give you the exact reference that would confirm the protocol though

On the HSI "digital counter display" of all airplanes I flew, rotating from 359º, it goes to 000º.
Then further to 001º, not 359º to 360º to 001º...
So, in order to be "politically correct" we should (probably) say "000"...

I am not that stupid. I know that 360 is 000... I am proud postgraduate from kindergarden.
Yet it is runway 36 R, not 00 R...!

Same story with digital time.
Do you read 23:59, then 24.00, then 00:01...
Or is it instead 23:59, then 00:00, then 00:01...?
How about, tonight at midnight, have a look at your clock...?

Anecdote with PanAm airlines. We had some departures at exactly midnight.
Yet on our paperwork, we entered T/O time at 0001...
And if we landed exactly at midnight, we entered landing at 2359. Why...?
Try to figure when it is 24:00 on 17 October... early morning or late evening...?
