Quick comparison given in the video...
- Current: "... cleared direct THUMM, resume the PRYME TWO departure, climb and maintain 10,000, comply with restrictions."
- New: "... cleared direct THUMM, climb via the PRYME TWO departure."
- Applies to any SID (not just RNAV SIDs) containing crossing restrictions with altitudes or speeds. (Just like "descend via", this excludes any "expect" notations.)
- Instructs the pilot to "navigate laterally and vertically to properly join the SID profile."
- Can be issued during clearance delivery (i.e. we can easily streamline a reminder to pilots why we're not giving them an initial altitude in L30).
- Speaking of L30, note we as Center working L30 could still clear people all the way up to cruise (during clearance delivery or radar contact after takeoff) but still deconflict departure/arrival streams by amending the "Top Altitude." Example: "Climb via the BOACH5 departure, except maintain FL280."
- A "climb via" clearance cancels all previously issued speed and altitude restrictions and replaces them with those depicted on the SID.
So, since this is the "Ask ZLA" forum, I suppose I must end with a question. And here it is (actually, a couple of them): Will the training materials be updated and students subsequently trained on this new phraseology; similarly, do we expect to have any operational need/desire to use this phraseology in our specific airspace?
