I am currently studying the ground school for CPL(H) (not ATPL) with a school in Coventry!
I have their Met file open in front of me just now and, large as life and twice as ugly, it hath writ, SALR = 1.5 deg C per 1,000 ft.
Paco, would there be a difference between the figures that a student would use for CPL exams and ATPL exams?
Cheers
