Greg, One of the problems when you are learning the theory side of the art during initial licence training is that you only have time (and syllabus...

As Bob indicated, above, the pilot calculations are a tad rubbery. Please keep in mind that the ISA calculations for pressure and density variation...
Some comments I wouldn't normally make but, in the case where the confused student is well accustomed to detailed formal study, a different approach m...
Setting the question for the sloping section of the limit line is the logical thing. However, to exclude the other considerations, the question real...
