I wanted to point out that Aerotronics uses regular paint on the panels
and stickers for the lettering. "Stickers" is probably a bit derogatory,
because they are really high quality and you really can't see the edges unless
you look closely. I'm not sure how the stickers would hold up over
time.
Lancair sends the panels out for powder coating and silk screening, much
more expensive, but much more durable.
Paint is easier to touch up, but powder coating is tougher.
I did mine myself using a base coat, custom made transfer lettering, with
a clear coat over the top. Very tough for a "homegrown" system. I
added a flattening agent to the clear coat to get an eggshell finish.
You definitely don't want a glossy panel.
Mike, Et Al,
Panel implementation is interesting because it must be used in real life to
help functionally fly the airplane, monitor systems and not distract the pilot
from occasionally looking outside the cockpit - day or night.
Some notes:
1. Another possibility is to find someone with quality graphics
equipment (computer, cutting plotter/printer, etc) who can make terrific
indestructible cut-out label strips with holes for switches etc. I have
used such with clear/white lettering to let the panel color come thru and
black/white lettering for control knobs and certain switches. Application
is simple and the labels can be moved later - I have moved the emergency gear
extension placard 3 times. They are very durable. They are easy to
add as new switches are added. I must have added 6 or 7 since first
flying.
2. If your panel consists of prehistoric steam gauges with glass faces, a
shiny panel finish will not increase the glare. If modern dulled flat
panel displays are mainly used, having a matte finish on the panel is a
benefit. Labeling material with a flat finish is available.
3. LNC2 and LEG2 canopies were designed to maximize nighttime
reflections of any illuminated object (including bald pates, should you have
one) and the dark colored "dust cover" extension over the panel is
crucial for providing the narrow forward see-thru band one needs at
night. Drawing the Koger sunshade at night helps to block
some overhead distractions. The dust cover should be
experimented with in a darkened hangar with lighting in the cockpit to see
the reflective affect on the canopy.
4. The color choice for panels containing black faced steam gauges requires
consideration. Black is not good because it requires mental work to locate
the instrument data in a sea of black. I found this in an experiment where
I removed the Royalite covers from the black underpanel on a Skymaster.
The instrument flight visual workload was increased trying to pick out
individual instrument data. White is not too great because of the
excessive reflective quality at night. A darkish color that provides some
contrast with the individual instruments seems best. I have no experience
with modern flat panel displays except that I have no trouble finding and using
the Garmin 430 display, day or night.
5. Labels should be generic. For example, "GPS" rather than "UPS
GPS", "A/P" rather than "S-Tec AP" so that equipment changes, like Garmin for
UPS or Tru-Trak for S-Tec don't require re-labeling. "On" and "Off" are
good generic terms to include around a labeled switch.
6. Even though everything has been thought of for the panel, those with
removable sections best allow for future changes. My fixed fiberglass
panel seems to be the item that resists moving to a Tru-Trak AP (with the little
plane in the window), since one 2.25" instrument could replace the 3.125" TC,
DG, Computer and a few switches like GPSS. Ugh, what would I do with
the three gaping holes across the bottom of my panel?
