WC:
Regarding the regionals - I think I might understand how they got there - and it probably wasn't all profit and short-sightedness. Perhaps it was more along the lines of: 'Why install equipment and/or upgrade to aircraft capable of doing things we don't currently need to do?'
D2D:
Am I to understand that while we opened with approach types, (ILS, VOR/DME, RNAV is what I assumed) it seems your issue with Honeywell's database package is more about arrivals, as in published STARS? Or is it possible there is a language difference between us? If so, I apologize.
Meanwhile, I can vouch for the correct nomenclature and definition of Q-Type approaches used by Honeywell as being NDB with DME per ARINC and if we are talking about airport approaches, I would suggest getting Aterpster in on this discussion - if anyone here knows about approach data and design, it is he.
