@ JW411: I am aware of the aircraft limitations of RJ1H/RJ85/Bae146/E190 etc. I was however talking about A320-series and B737-series from various operators who will not say anything when they reduce from 300+ kts to 250kts when i've told them (at least 1 time) 'Keep speed xxxkts or greater until advised, also below FL100'
@ His Dudeness:
"How may times you think I was at the hold, say, number 3 at the exact slot time and wasnīt being allowed to takeoff? So we canīt demand/expect nothing at all, but then, we are allowed to pay for that? Is that what you are saying?"
No that is not what i'm saying, I was only saying you can't demand to depart @ CTOT -5 if you are ready and waiting. The aim of slots and Flowcontrol is to depart exactly at that calculated takeoff time or as close as possible, with a small window to enable outbound sequencing at the rwy. You can see it as sh*t, but maybe what you need is a visit to a larger and busier centre during an Inbound-rush.
