isn't it funny ( tragically so) that if planes were on VOR airways, that VOR's would have enough slop in receivers and autopilot couplers that no one would be right on the centerline.
I recall reading how in the Aural Range days (.- -. ) how pilots would fly to one side as the definition of the beam was sharper.
to barit 1, being 100 feet off on altitude would have been enough wouldn't it?
I read just today that the crew of the legacy said their TCAS did not issue a warning.
While it is too soon to know for sure, couldn't a bonafide failure of equiment, including the new transponder in this brand new plane be part of the equation ? This would accomplish the same thing as if the pilots had turned off their transponder. AS the legacy survived, a check of the transponder, TCAS, and cables/antennas are in order.
