Bad METAR crashes flight Hpa read as inHg

Just a small observation:

I was flying over TNCM - METARs in the Caribbean often have "QNH" in both HPa and in Hg With a "Q" before the HPa and an "A" before the in Hg. However when the METAR for TNCM updated it read A1017 A3003 (should have been Q1071 A3003) FSreal WX of course dropped the system pressure to 1017 in Hg which added about 20,000 ft to my indicated altitude instantly. The JARdesigns A320 FMGS didn't like that a bit and that was that for the flight

Maybe you can consider some protection against such bad METAR strings in future updates.
