Bargy,
But Metars are not listed in the 3 types of QNHs "am required" to set "prior to passing the IAF" (ENR 5.3.1). That is my point. Since Metars are NOT an approved source (5.3.2), then I can't use it at all because it's not listed. Perhaps the rule was drafted poorly, and the intent was to allow us to use Metar QNH, but that is certainly not what it currently says.
Without being too pushy, what rule do you reckon allows us to use the Metar QNH?
Of course, in the old days (prior to 17Apr) there were no rules (except the sources that constituted "an approved source" and the -100ft business).
