thanks for realizing the difference between the two.
MAY I OFFER THIS as to the screwup which caused this crash?
IF the captain thought he was high, he would be looking for a papi which showed him high, not low.
BUT WHAT IF he saw something that looked like a HIGH PAPI? Something NOT on the airport?
What if it was something like a car backup light? Or something else.
Being programmed to see something showing you high, might make you look at something OTHER than the real PAPI. And perhaps we will not know as the vehicle may never be there again(where ever THERE was).
Again if you are doing an instrument approach to minimums or below basic VFR all callouts should be bmade and one person is inside monitoring the approach.
