alf5071h,
I wasn't sure whether you had missed the significance of the erronoeus glideslope as opposed to the false G/S due to multipath reflections that we all learnt about in days of old.
I think most aviators including me were totally unaware of the possibility of the erroneous G/S been transmitted in the ground test mode until the initial reports of the NZ incident first surfaced in the aviation magazines around five years ago. The distinction between erroneous and false G/S was drawn in the investigation report.
Your posts reflect a huge depth of experience and are always very interesting and enjoyable to read.
Cheers!
