If I can attempt to summarise, then?
It seems to me that track miles/speed reductions have been 'fine-tuned' a bit following this thread. Thanks to the ATC teams.
Regarding Min speeds, we need input from the 'heavies' here, but how about targets of
1) 230kts
2) Then 190kts
and finally
3) 170 to *5* which would allow us in BA (and possibly others) to be certain of achieving our approach 'criteria' as mentioned earlier.
Lets have some more input from the pilots please. Would these speeds suit just about all?
