G'day Bob,
Just commencing CPLH Nav and hit a snag early!! Questions 8 and 9 have me stumped with the answer explanations. Page 181.
Q8. ISA Temp at FL140 is -13, OAT is +7 so it's ISA +20.
Q9. 15000ft ISA +10 is a density height of 16200ft. Is this plus 10 degrees to get to -5 degrees?
If you wouldn't mind explaining that a little further for me that would be appreciated.
