Altimeter Check
Very Dangerous quoting old AIP reference. The current date for ENR 1.5 - 32 para 7 is 27 AUG 09
Currently if there is an unexplained discrepancy at the check point then an immediate go around is called for.
So if temperature has been taken into account and all is as calculated then continue.
And remember a correction calculation must be made for every check height,
GS intercept-OM/DME check and minima.
