Hello all.
I have a question about Isa deviation and I can not work it out.
the details are 12000 feet and 0c.
15-24 gives an Isa temp of -9 but the deviation is 9.
the problem I have is I would have thought this is -9 and don’t understand why it is a positive not a negative.
if anybody can show me what I am doing wrong would be great.

Thanks. I think it just clicked. The deviation is +9 to get from -9 back to 0.
so for 2000 feet and 2c you would end up as -9 because you have to get from 11 back to 2.
is that correct?
