I would like to mention one more thing regarding the VNAV - hopefully, there will be functionality sooner or later for PROF to calculate a descent at an appropriate FPA rather than just going into VFLCH mode when PROF is pressed. VFLCH, especially at 300-320 KIAS if you're trying to go fast, makes for a pretty Space Shuttle style descent with this flight model. Ideally, I'd like to just calculate an appropriate 3.0 degree path, whilst setting say 315 as my selected speed in the box, which it then calculates the TOD from that so it is gentle and smooth.
