3 degree G/s = 318.44 feet per mile. 2.5 (318.44) + 46' TCH = 842 feet.
All these calculations assume the full ILS was used. The narrative refers
to a 376' minimum altitude, which was the localizer MDA at the time of the
accident.
I doubt anyone knows whether he was using LOC or ILS minimuma.
The NTSB doesn't even understand the concepts:
"The ILS 36 has a minimum approach altitude of 376 feet above ground
level (AGL). The cloud ceiling was at 500 feet AGL. After the accident,
the ILS 36 was taken out of service to be tested. It was flight checked
on December 24, 1997, with no anomalies found."
What does "minimum approach alitude" refer to?
What does "376 feet above ground level" refer to?
If the field office investigator can't sort oout MDA, DA, and HAT, I
don't expect to figure out much about his or her's view of how the
approach was being flown.
