So does "Cancel STAR speed restrictions" include cancelling 250kt below 10000', or does it just mean cancel the other speed restrictions such as 230/20, 185-160/10 and 160/5.
When ATC cancels all STAR speed restrictions this includes cancellation
of any general requirement to maintain 250KT or less below
A100.
It will actually cost me (or my Company) fuel and therefore money to cancel these restrictions, so do you: want me to; need me to; or is it just that you don't need to restrict me any longer. I don't know what you actually want or need me to do so I often end up asking something like "do you want or need me to increase speed?" because I'd actually rather just stay with the original plan at this late stage.
If no other instruction attached, then continue at your normal or desired speed. If I want an aircraft to increase above 250 or hold it on beyond the STAAS reduction points, then I'll be specific.
On departure though, if I cancel speed restrictions (without being requested), it's always because I want you to start accelerating (but still meet any height requirements).
