High Speed
Recently, in the vicinity of a class C airspace, we were doing the usual 250kts below 10K when we were instructed to maintain high speed as we were vectored on the downwind, when ATC asked us to maintain high speed, he didn’t seem happy with the 250kts, or so we thought, so we maintained 280kts as long as possible in anticipation of the base leg. The question now is, when pilots are asked to maintain high speed, what exactly are they supposed to do? Or how fast are they supposed to go?
Thanks
