Re: When pilots speak of a specific type of aircraft as "unforgiving" does that indicate a design flaw?

Not a 'deficiency' per se, but narrow margins for error and/or rapid changes in behavior despite overall similar situations. You won't usually notice it in regular operations but the design 'does not forgive' large deviations. For example, some aircraft will give clear and early clues of an imminent...

Airbus aircraft (and I believe all FBW aircraft) have an entirely artificial feel, since they lack a mechanical connection to the flight control surfaces. Usually they try to go for low forces to reduce physical exhaustion.
