<<EGPWS and SCATANA downing of GPS
Anybody thought about the legality implications for the mass of EGPWS users who might have a CFIT if the GPS was suddenly switched off or degraded significantly?
Let's say that at any one point in time around 7500 EGPWS using airplanes are flying around and someone pulls the GPS plug, perhaps as a SCATANA measure.>>
Ok, lets presume all this happened, Belgique, and all the EGPWS units in aircraft worldwide failed all of a sudden.
Hmmm, well, if you have to use EGPWS to avoid the rocky bits, then I guess you would be better off firmly on the ground.
Strange, ain't it.
Thousands and thousands of aeroplanes managed to avoid the lumpy parts simply by knowing where they are, flown by professional crews for many many, many years.
Gee, what a surprise...
