How much must we add to the current alt, when OAT = -xx?
Jammed Stab
Good point though. Do these corrections take into account a standard lapse rate or a uniform temperature in the column of air.
I think is has got to be OAT. "If OAT = -xxdeg then at y feet apply n feet to give altitude required, something like - "if at -35 deg if 1,000 needed then cross at 1900
Edited -
ad nauseam . . reason for editing: because I am being silly and I cannot write.
The original question OP thing, should have read. "How much do we add onto the readout on the altimeter when the temp is very low like -35 or something degrees . . . ?
I looked at the CAA thing . . .I think they have got it too low (i.e., not enough), but what do I know . . ?
I was trying to follow the chart above, similair to the CAA one but I am suffering from (GIS) Glenfiddichorial Influenza Screwupsynapsisdislexium - which as you know is a terrible condition - I have only perhaps 45 years to live tops. I have been out of action now for quite some time - at the end of today it will be . . . . . yep, 7 whole hours. Yep, thats it guys, its finally got me - The Common Cold. I would like to thank everybody for tolerating me over the years, and please leave my Canary `Boeing` to some nice old lady - who will look after him and stuff him full of food and let him out of the cage, twice a day, he will find his own way back in again.
Back to the problem, which I am trying to solve before the great partyer in the sky takes me to heavens where all the babes are blonde 25 and non virgins. . . .
. . and with my last dying breath:
