but isn't 'min clean' 'min clean'? When min clean goes up with s/b, so will your IAS? ATC have to put up with that and will probably not notice in reality. Just fly faster?
BOAC: I agree absolutely with you, but on the day it was evident that ATC wanted us going as slow as possible. To make the constraint we needed S/B and at least 270 kts to get down. So a good 35kt increase in IAS. If ATC "probably will not notice" then indeed I was worrying unnecessarily. Tiz why I posted here. To get some idea of what was really expected of me, and to explain some of my constraints on the day.
