Does the airline have any Cat A, B, C or E aircraft? There lies your answer i suppose!
If you are going to try to remember all these speeds is there enough memory for other stuff like....Fleet size? ....Destinations? Wing span?....engine power output?......seating capacity?....what is mach crit?.....what happens to the c of g after mach crit?...whats V2?...whats swept back?...what are the winglets for?what happens if one is not there? if two not there?....types of flaps on 747,777?...what is super crit wing?...when do you change kts to Mach?...what is RVSM and the altimeter limits or Nav equip req?.....How about RNP?.... man the list goes on!
If you want to learn these speeds i personally think Cat D.
Good Luck with the interview
