A certain operator of DHC8 aircraft from a state that is sunny refuses to use the IFR pick up procedure. I would be fairly safe to assume that for the same reasons they will not use the ohter 2 new procedures for climb and cruise. The unfortunate thing is that if a pilot/company is uneasy about using the procedure and they elect to never use it, they will by default be using it as the other people who elect to use it will just wizz by with no separation applied. This may be ok in radar airspace where they can request avaoidance advice but in no radar airspace the relatively easy vector are unavailable.
/me reminds everyone of G demo and whacks a $20 note on the table. I give it 2 months.
