you guys usually just request a block altitude so you’re not committed to achieving that higher flight level?
and yes.. FL470 and Mach .92 sounds impressive... unless you’re a former SR-71 driver lol...
or shuttle astronaut...
i’m sure babying the aircraft at those altitudes is critical.. some new CRJ pilots don’t always understand you can’t go from F380 to FL400 by just hitting speed mode and dialing back the Mach number.. gotta coax it carefully..
