Hiya,
Looking through my air law book, a bit confused about altimeter setting proceedures, would someone mind just setting me straight?
Above 3000ft on a VFR flight you can set the standard setting of 1013, and follow the quadrangle rule. What happens though, when passing under, say, LTMA who's base is 4500ft. Would you have to reset the altimeter to regional to avoid infringing the airspace? Do VFR flights above 3000 just use regional QNH, changing the setting when crossing an ASR or do they normaly use standard?
Thanks for the help.
