Doing some studying for the ATPL written.
Can someone explain how one would go about doing questions 75 and 76 in the FLIGHT OPS GENERAL section (page 7-19) in the Aerocourse workbook?
I'd scan it in, but I don't want to break the copyright.
I can't find a single reference to this stuff anywhere.
Thanks.

Moving,
#75 ISA temp at FL300 should be -45 C. difference between -45 and -39 is 6 degrees{-45 - (-39)}=-6. Use chart, FL300 at mach .74 is -19, so {-19 -(-6)}=-13. Answer -13 degrees C.
#76 ISA temp at FL250 -35, difference between -35 and -42 is 7 degrees.
Again the chart, FL250 at Mach .78 is -5, so -5 - 7= -12. Answer -12 degrees C.
