ManaAda, anything between 280kts and 320kts could be considered normal for most jets, anything less is acceptable, but a little nudge to say "we'll be going a bit slow" helps the plan. We do get quite accurate ground speeds on the radar display, however its not normality I'm on about, its when we have to trail using speeds.
Bomber, exactly what I was after and basically what I thought. We had an OPNOT produced warning us that in certain conditions, 737NG a/c may have a limitation due de-icing, and that is it. Nothing was added, and we are never to know if an a/c has been de-iced unless you up front let us know. The biggest shock was less than a week ago (and could show ATC nievity on this subject), when it was 20+ degs outside in glorious sunshine, and after a little hard vectoring the number one a/c THEN said he couldn't take the highspeed descent, and numbers 2 and 3 were further weived around and sailed into another sector to get the 10 miles in trail and still meet the height restriction.
I don't know what solutions would work for this, and think it'll just come down to what already happens. Hopefully word will do the full rounds and everyone can let us know early enough, if not, please don't get too upset by any extended sightseeing trips you may encounter, and excuse any puns you may hear, we aren't let out that often
