So I can't seem to understand this chart.
http://a5.sphotos.ak.fbcdn.net/hphot...43973570_n.jpg
On the bottom it has two little examples.
For number 1) I understand the correction of -200, but I don't get how the 2300ft QFE = 933 HPa.
And I don't understand any of question number 2.
Anybody?
Thanks!
