Lazy, no. Just a different skill set. Although the FAA has recently put out an AC about their concern for the degradation of "hand flying skills", I think this is a rather one sided view of a larger issue.

A general definition for levels of automation can be used to help define this issue. In general, automation levels start at level 1 - No automation, to Level 4 - FMS based Automation.

The older pilots tend to be solid with their hand flying skills, and to different degrees are comfortable with the automation up to A/P on and vertical speed, FL CH, Heading select/Hold, etc. But most don't become familiar with the FMS enough to be proficient with it.

Conversely, (I'm generalizing again), the younger pilots seem to be much more familiar with the FMS. However their stick and rudder skills aren't as strong.

Obviously the individual's initial training bears most of the responsibly for this. With a limited amount of time for training, the main focus of today's programs have switched more toward an emphasis on higher levels of automation.

I think it is important that pilots are skilled in all levels of automation, from no automation to a VNAV CDA, RNAV AR .1 RNP approach.

I think a focus on one over the other is misguided.
