Hello and Happy New Year to all!!!I got the following commands from Mexican Approach into Guadalajara, Mexico airport (MMGL). "Q and H 1017" and "Q and H 1020". Can someone give me some understanding as to what these mean? I could not locate them in the Radar Contact version 3 manual.Thank you.

Sure thing,They're actually saying "QNH" In the United States altimeter settings are reported in inches of Mercury. 28.76 / 29.92 / 30.25 etc.In other parts of the world altimeter settings are reported in Hectopascals. The pilot/controller glossary defines QNH as "The barometric pressure reported by a particular station". When the controller tells you the QNH is 1020 (30.12 InHg) they're giving you the altimeter setting. :-)Michael CollierDispatcher/SOCAmerica West Airlines

it's the pressure in millibars, instead of inches of mercuryjd
