High level inbounds EHAM have a requirement to be FL260 22 nm N of EEL, tacking about 200; in practice FL 260 at EEL is OK although some pilots push this to the limits with R.O.D. of =/- 4000fpm, to considerable annoyamce when we were busy.
This lead to the instruction, "The number is 260; either descend to it, or turn to it." i.e., expect radar vectoring to the back of the queue. It worked for a whle.
