thanks so far, I thought I'd go for a cheeky title (pun intended) go coax some responses and with 274 looks so far, not a bad return.
Vintage, I'm interested in the 10 minute average that you use for the Metar, I gather your equipment does this for you, am I correct?
And how does a pilot know that I am giving a 2 minute average wind? Is this buried deep within an ICAO doc somewhere?
