It could be you're late and the guy following is early - for us the best solution is to speed you up as it doesn't reduce the gap behind the other guy.
Correct! Growler, exactly
when do you hit the fix? T+0 seconds? T+50 seconds? 6 miles a minute could be a gap of 11nm or 1nm.
Given a speed reduction just prior to a height requirement, with no height waiver.
If you need vectors to get down, you're using extra fuel due to extra track-miles; you may as well just pull out the speedbrakes and stay on the STAR.
So, why don't we have max/min IAS requirements on STARs or downwind or base positions, like most other countries?
Over here, we have a feeder fix time (minimum 36 track miles to run) and thereafter 250KIAS. Does the job.
