The finely-tuned hand flying skills are a byproduct of the pilots having total situational awareness.
I disagree. Finely tuned hand flying skills are a byproduct of
practicing finely tuned hand flying skills. It indicates a practiced skill at
hand maneuvering an aircraft, and implies nothing indicating a superior awareness of communications or of events taking place outside your aircraft. In fact, if hand-flying precision is proportional to mental concentration on such precision, it implies an inferior awareness of communications or of events outside your aircraft.
It's when pilots aren't on the ball, that they begin "wrestling" the aircraft through the skies.
True, and self-evident...I don't know about "on the ball", but if the pilot is not practiced at hand flying skills the pilot doesn't hand fly as proficiently as the pilot would if the pilot was practiced at hand flying skills.
The SA Skills required to fly a non-automated aircraft such as the DC-9 are MUCH greater than those required to fly any of today's Electric Jets.
..No doubt about it! And that is exactly the point... your SA "capacity" is more taxed with less automation, that is why automation has been put on airplanes!-to reduce your SA demands and thereby increase your SA capacity. SA = Safety
