HN39, O.G., my thanks for clarifying yet another item. For a pilot this is really interesting.
Apart from understanding how all this works, it leads me closer to conclusions that such knowledge remains valuable to our craft for those flying transports and that "nuts-and-bolts" courses, far from being replaced by notions such as "managing the aircraft", are still relevant to what we do (and did!) for a living. Continuous education is the responsibility of all professionals but it would be interesting to revisit curriculum design for pilot courses for the Airline Transport License and at the airlines where training footprints, concerning fbw (C*), autoflight and aircraft performance topics. Anyway, that's for another thread! Once again, thank you.
