Hi,
gums and OK465
AA flt 965 almost cleared the hill by crew action (based on GPWS).
Crew errors, data base deficiencies, etc. played a role.
Clever System was developed and introduced "in the aftermath" of this accident.
PS
The combination of errors was reflected in the percentages:
In June 2000, the jury found that Jeppesen was 30 percent at fault for the crash, Honeywell was 10 percent at fault, and American Airlines was 60 percent at fault.
