411A “with one type...of course”
You clearly lack a wide range of experiences, also apparently a weak knowledge of Ahhh, which belongs to de Havilland.
The Avro RJ (from the de Havilland stable), delivers consistently good auto landings.
In addition, the RJ flight system design eliminates the need for routine proving of the system; any degrade is annunciated to the crew, thus if en-route a diversion can be planned before arming the approach mode. Unfortunately many of the operational certification authorities have difficulty in providing a dispensation from existing inflexible rules.
