speed reduction to 250 IAS
Hi everybody
Is there any time limit for speed reduction from a descend speed of, say 300 IAS to 250 IAS when radar-vectored in the approach area?
A figure of 2min / 1 min was mentioned.
My understanding was that one should do it asap..but don't know if asap is time limited
thanks for your time

I'd imagine it's very variable in terms of what you actually get, but I've always worked on 1K per second... So around a minute is reasonable for this request, but it depends on what the a/c is doing, on a good rate of descent etc will get significantly less reduction in speed when compared to level flight.
Try getting an A330 or A340 to climb at anything more than the curvature of the Earth ... at any weight
Seriously though, ATC do not expect instantaneous speed reductions and don't plan on them. Those lucky enough to have Mode S downlinked parameters can soon work out how quickly the IAS is changing
