At the beginning of the report is the following quote:
They had Flight Control Computer B (FCC B) selected as the so-called Master FCC, and had selected Autopilot B on. FCC B has its own independent radar altimeter. The training and documentation available to B737 pilots suggests that this would be sufficient for protecting the automation against left radar altimeter anomalies.
Does anybody know if the lines in the MEL that require the rad alt breaker to be collared and the A/T not to be used for approach or landing were added after the incident?
