rustle
I do not understand the term "Trolling", perhaps you could explain.
I am concerned over what I assume from your comments is a mishaprehension.
Is cold air, as I thought, denser or not. If so, I believe that as the pressure depends on density, the cold area would be a higher pressure than its surroundings. I have looked in my husbands old Birch & Bramson, which tells me that flying into a LOWER pressure area will result in a situation where one will be lower than the altimeter tells you. This I understand.
I had not looked into MY Thom book, only having had it for less than a week, untill the posting from HWD made me look.
The part I have trouble with now results from the statement in my book that it will be, if my understanding of pressure/ temp /density is correct, the other way round.
I almost wish I had not looked after reading the post originally
Please feel free to educate me if I have it wrong rustle.
I will take it up with my instructor next week anyway.
