IMHO I think it is better to reduce speed during
the descent rather than hold. Holding requires more
attention as I have to ensure the acft leaves the
hold +-30secs. If there are 4 guys holding
much more attention is required. What I would like to know is how much to
reduce in terms of Mach No. to lose 1 min. Then I can either
vector out or reduce further before they hit F260 and below.
Is there any quick calculation?
