Heavy aircraft high speeds
There are plenty of occasions before becoming established when you are able to advise of your operational requirements. Tag it onto the end of a readback.
Flying a 744 with a landing wt of 302.0 tonnes means a Vref of 158kts and a Vvat of 163 min or as much as 170kts. Makes 160 to 4nm and then slow down hard to do so we just tell the ATC bods nice and early and they are as pleased as punch at a bit of prior warning. Also I always nominate the turn off I expect to take so as to make their job a bit easier. It's a two thing you know and NO excuse for not knowing or being able to let them know. It was all talked about in the briefing so let ATC know asap.
