Ok, this might sound pedantic, but it becomes relevent when we are doing altimiter checks accurate to 10' in RVSM airspace:
When you call 'set standard', what do you set? Most set 1013, which is not quite right. I understand that you should set 29.92 Ins (on the other scale), as this is the STANDARD pressure setting of 1013.2mb(hpa).
29.92 is EXACTLY 1013.2 (multiply by 33.86389).
Is this right?
