Can EFIS / EFMS lead to removing basic safety checks?

Look, these guys *thought* they were on runway 22, obviously. So if
they'd been in a plane with a regular DG, and realigned their DG to a
"runway heading" of 226 degrees while pointing down 26, what's the
difference?


These airplanes don't have DGs that can be set in that manner. In the
accident aircraft it was either flux-gate corrected gyro compasses or
inertial referenced compasses; neither of which are set by the pilots in
a Cessna 172 manner.

Hence the first clause of my sentence, which said, "So IF THEY'D BEEN IN

Why do you have to be in a plane with a regular DG to complete a
checklist item that compares compass heading AND HSI or EFIS heading to
anticipated runway heading?

Wouldn't they have been likely to notice a 40 degree discrepancy if the
item had been on the checklist?

We are concentrating too much on the specifics of the technology instead
of the original question asking if modern technology has allowed us to
skip or eliminate useful checklist items.

There probably is a yes and a no answer to this question. The point is
to think about the possibility and take appropriate actions.

Oh, okay.
