Altimeter setting
Can anyone relate on how and when to change altimeter settings to Standard when cleared to a FL by ATC while in NADP1?
Can't find any rules in Airbus manuals or my company manuals.
It makes sense not to change it until after the NADP1 due to the fact the altitude might change to the higher of the standard setting on 1013hpa, which would implement an earlier acceleration altitude then the NADP 1 stipulates. (and thus bust the procedure...)
I'd just like to know if there is a rule or procedure written in black and white on this....
Cheers!
