If both FCC commands must agree for trim commands to be valid, then malfunction of one FCC can be suppressed.
Since when has aviation done anything other than dual architecture?
Who in the Boeing design team thought single architecture was a good idea?
Who in the Boeing management team thought single architecture was a good idea?
Who in the Boeing flight testing team thought single architecture was a good idea?
How did a single-channel MCAS ever get fitted to a 21st century aircraft?
