I think the knowledge of the answers are there, I just can't sort them out yet.
The questions were posed as several, so the answers may be clearer if I knew which question is being answered. I think I got it that TAT includes kinetic energy (friction?) effects? while SAT doesn't.
I couldn't tell if "frigate" was answering a temperature question or a speed vs altitude question.
As I understand the speed vs thrust vs altitude question, one needs to sort out what level of thrust coresponds to max power at the two altitudes in question and then to sort out what expected aircraft performance would occur in speed for this thrust.
If the question were meant to answer the speed question for the same thrust at two different altitudes then the answer may be more straight forward.
OK I'll stand back and see what answers go with which question
