Hi RetiredBA -- I think you're being a little bit mean-spirited. I was trying to answer Hebog's question (9th March at 1303) and from his/her profile it looks as though they are not a pilot but someone who has a personal connection with this tragedy.
Hebog asked whether the pilot would have had to do mental arithmetic if there was a discrepancy in his altimeter. I thought that introducing the concept of 1013, Regional QNH, Airfield QNH, QFE etc would just confuse. So I stuck to the fundamentals - an altimeter is little more than a barometer with a knob. I hope that my simplified explanation won't have "lethal" consequences and in any case if Hebog isn't a pilot he'll probably have a few flying lessons before he flies solo.
I was unable to answer his post in full perhaps you could have a look and see if you can help.
