Quite right, though each manufacturer of the experimental EFISi has their own
ideas
on
symbol weight, color, and font. As you move up to the heavy iron EFIS, things
seem to
standardize more to something more high-contrast and bold sans-serif than BMA
and
Dynon. But human factors engineering is notoriously non-obvious.
Dynon's product is promising and certainly inexpensive, but I think they were
caught
off guard by the intense engineering effort required for something as
mission-critical
as
an EFIS. It also strikes me that the D-10 and the EFIS-lite will have only a
limited
market
as back-up instruments. Their small size eliminates the biggest human factors
benefit of
a glass EFIS - better information presentation in a comfortably sized display.
It is unlikely
that many steam gauges will remain in a panel that uses an EFIS ( take a look at
Ira's website ),
whether retrofit or brand new; the panel will ultimately be designed around the
EFIS.
BMA's and GRT's approaches are ultimately better because they've realized this
and
used large screens from the start. I give the nod to GRT because they've
substantially
increased the the size of the EFIS display over BMA, which will be better for
those
without
20/10 vision (i.e., me).
Dynon may have a good product, but in my opinion if they don't follow up
IMMEDIATELY
with a
GRT-sized display at around $3K their long-term future will be in doubt.
GRT suprised everybody with a well thought out and configurable product that is
far better
suited for new panels, and, to their credit, they didn't even talk about until
they were sure it would work.
The shakeout begins.
