Bloggs,
It might not help with delays (as you so well put it, 40 just doesn't fit into 24!) but it will help us controllers as jets and props will be on different SIDs/STARs so we won't have to push planes around to get everything to work. Provided the weather is nice, it will be a big improvement for us doing the radar enroute around PH - when the weather turns to poo though, it is going to be very ordinary!
On the ADS-B thing, even if every aircraft flying through WA had it, nothing would improve with delays as there is no ADS-B feed into the PH TCU for the flow. All the flow sees are squares (flight plan tracks, ie don't know where they are) or circles (radar tracks). Until they equip PH TCU with the ADS-B feed, there will be no improvement. When will this happen? Got a date yet for hell freezing over?
Also, ADS-B was supposed to have been fully rolled out, completed, operational, yaddah-yaddah-yaddah for 5nm separation by now across the whole continent above F300. Ask any manager in AsA when it will actually get to that point and all you will get is a shrug of the shoulders.
Once ADS-B is all done and the feed is delivered into PH TCU, provided there is decent coverage at turboprop levels out to 250nm+ from PH, there should be a big improvement in the service you receive (won't have to use a procedural standard) and delays will be much better handled as the flow will be able to sequence from an extra 100nm+ out. I wouldn't hold your breath on that happening before 2012 though.....
