and didn't know how the auto throttle works
My whole airline didn't know how the auto throttles worked. Our manuals, approved by the FAA, and our training, told us that with the Autothrottles ON, we would be speed protected. We didn't know about this autothrottle (non-speed protection) mode until the SFO accident.
The above is a MAJOR problem. Boeing knew how the system worked, but didn't communicate that effectively to my airline.
