Can EFIS / EFMS lead to removing basic safety checks?

Placing the runway heading on a steam gauge HSI was considered good form at my company

Why? The runway heading is rarely a factor of ten on the nose, and
having an even heading is only good for an instrument takeoff. So,
you'd be usually setting the DG to an incorrect heading just before takeoff.

Makes no sense to me.

I am not speaking of DGs, Jose. This is about an accident involving air
carrier equipment.

We set the exact runway heading. Often, the departure clearance is to
fly runway heading. Even if it is not, runway heading is to be flown to
at least 400 feet.

Our steam gauge autopilots or flight directors all had a heading mode.

The EFIS/FMS birds had a heading mode and a track mode. ATC got unhappy
with folks flying track mode when they were instructed to maintain
runway heading; thus the reason for today's AIM language in that regard.

I cannot image why a professional crew flying today's air carrier
euipment would not set the runway heading. It could have saved a lot of
grief at LEX.

I infer you mean that you set the heading bug on the exact runway
heading, not that you set the DG to the runway numbers (times ten).
That makes more sense.

Airliners don't have light aircraft type DGs. It is either an HSI or,
far more likely, a track-up moving map with an appreviated compass rose
at the top. Or, like the G-1000, it could be an electronic HSI.
