Capn Stable,
The opposite can also cause drama. The ILS at Guam in 1996 with the G/S out has high ground on finals with a ****** factor of the VOR/DME being 3.3 dme SHORT of the runway threshold.
In the landing configuration without EGPWS and no major closure rate the GPWS thinks you are going to land. It doesn't know there isn't a runway there
If the crew of KAL801 in 1996 had reacted (if they were able to after the long crew day...another link in the chain) to the "minimums" readout (and all the other radalt readouts 500 .....etc) they would probably have missed the ridgeline.
moral of the story. If an approach needs the radalt for minimums. use it. If not set it to something that MAY just save your @ss.
