Question about the "RNAV Docker(sp?)" phraseology included in the line-up and t/o clearances. Up here in Western Canada I've never heard that before, so I find it pretty interesting.
1. Is it just part of keeping the controller/pilot procedure awareness at a higher level?
2. Is it only for non-commonly used SIDs or every departure?
3. With respect to both 1 and 2, is it a practice reserved only for KBOS, or does it happen at the other big ones in the US as well?
They're talking about a GPS waypoint. Specifically, DOCKR intersection on the KARVR RNAV SID from 25R at KLAX. Most of the major airports (at least here in the states) have RNAV SIDs and STARs.
