JT is right.
For example, when departing an airfield, in the L1011 or my private aeroplane, and as the first turn is started, I always look outside in the direction of the turn...when it's visual, of course.
Yet, I find many First Officers are too busy glancing at the FMS, to pay much attention to anything else, and even making selections, when this job is more properly done by the NF pilot.
Many new general aviation aircraft are now equipped with avionics that make even the best of the recent generation of jet transports look old fashioned, and FAR too much time is spent heads down.
This, in my personal opinion, from a safety standpoint, is NOT good, as when VMC, separation is see-and-be-seen.
