wrote in message ... The airlines are NOT making use of WAAS. They have basically told the FAA to take WAAS and shove it. Almost no airline aircraft have WAAS. In fact, all the aircraft produced prior to the early 1990s don't even have GPS unless they have been upgraded (a very expensive upgrade for that type of aircraft certification process). No, but they do use LNAV/VNAV with FMS-derived VNAV. Northwest and a few others got approval for this a few years back IIRC and that's why those new descent profiles started popping up on Jepp plates. It's also why the new approaches are all called RNAV and not GPS. -cwk.
