High speed flight is a real hotspot for JAR - why oh why I do not know. It is nice that JAR think we will all one day fly Concorde but I think there're more important things they could pound us on!
Learn all the temp/pressure/density changes through a shock wave at different mach numbers. Other feedback from my exam:
Bit muddled but that was my shorthand after the exam and it all don't make much sense now let me tell you! I passed with 82% so I guess I did something right for a change!
Good luck,
VFE
