Speedbrake Lever, only this morning I heard the following exchange:
NIGEL: Shannon NIGEL xxx requesting 370.
SNN: NIGEL xxx roger, I'll see what I can do.
SNN: OTHER zzz Shannon, what is your Mach setting at FL370?
OTH: Mach .80 Shannon.
SNN: Roger, thank you....NIGEL xxx what would be your Mach setting at 370?
NIGEL: That would be .84 Shannon.....but we can do anything you want.
SNN: Roger NIGEL xxx, I can offer you FL370 with speed restriction or FL390 unrestricted.
NIGEL: Ok Shannon, we'll take 370 with the speed restriction.
SNN: NIGEL xxx climb to FL370 and cruise at mach .80 or less.
pause.
NIGEL: Er, Shannon .80 is a little too slow for us, we'll stay at FL350 if that's OK?
I could just picture the poor fellow at Shannon banging his head on his console in desperation!! Face it Speedbrake, you drivers can be a bit blo*dy daft at times
