At which point the question must be asked whether a drop to Direct Law - in which pilots are expected to trim manually despite it not being part of their day-to-day operational habits - would be more risky than less.
It seems to me that flying a airplane manually (without the assistance of automation) requires that the pilot use the trim manually
This is certainly what all airline pilots make when piloting an aircraft non equipped with automation
Is that the pilots of Airbus airplanes or other brands equipped with automation have no longer know how to fly a Cessna 172 ?
