As a bus pilot I'm curious how the 737 handles an over speed with the A/P engaged?
It seems the me the Airbus logic of only providing increased elevator authority in 'Expedite Descent' mode to prevent an overspeed should also be provided anytime the speed is close to the barberpole in any descent mode, (maybe even climb, altitude capture logic etc permitting). The Airbus does not have an amber caution range for high speed like the 737, (again I do not know what the amber range on the 737 represents or it's effect on the AFCS, if any) rather, with the Airbus you are in the green or you are in the red. Over speed too much and only then will the A/P react (prior to this the A/T should have reduced, or the pilot intervened) In my view the Airbus managed modes are full of threats for newbies.
