The classic Cub panel, a
precursor to the six-pack
(airspeed, attitude,
altimeter, VSI, HSI, turn
coordinator).
While in the age of " steam gauges, " instruments relied
on classical physics and coarse (versus discreet) sensors to
quantify relevant aviation data in the airspace environment.
Their measures gave latent, relative indications of wind, ground
and vessel movement; time and distance traveled; and propeller
revolutions as an expression of power and efficiency. The basic
instrument panel comprised a set of commonly round dials and,
adjunctly if at all, a two-way radio and position transponder.
Steam gauges served for decades until the dials' limitations
were foiled by the digital age.
Thankfully, modern cockpits strived, at their very
least, to bring to bear all three maxims - aviate, navigate
and communicate. The fundamental change at hand was
arithmetical precision with which power, speed, space and time
could be governed. This all happened abruptly at the turn of
the century that was Y2K (an alarm expunged in its own hype).
The successor was GPS. In this new era, flight specifics were
plotted digitally, accurately and nearly instantaneously.
Round dial gauges of the then-common analog six-pack
transformed to a new silicon standard with GPS at its core.
The change started in general aviation with the hand-held
navigator. Quickly, a preponderance of silicon-based tools,
portable devices, found their way into the cockpit. This justly
led to their panel mounting, freeing the hands and cockpit of
clutter - albeit busying the fingertips.
In step with the May 2000 demilitarization of GPS
technology, and freeing impediments on its accuracy,
analog gauges began exiting the cockpit. Much like digital
television and flat-screens did away with the picture tube,
so went the round dials of the instrument panel. The
" glass-panel " cockpit, a perhaps more seductive term
than flat-screen avionics, became pervasive. Glass-panel
innovations took their lead from military cockpits and
the personal computer. Digital displays emerged, and the
analog six-pack was cast aside.
Glass-panel, flat-screen avionics brought silicon to the cockpit.
The glass panel would change flying forever.
Celebrated at the outset of this transformation was the
Dynon EFIS-D100, a first among many electronic flight
information system offerings, giving pilots a glimpse of
the future. Crystals snuffed out cathodes, dials turned to
tapes, and light-emitting diode arrays replaced needles.
Every detail, and then some, of the six-pack panel
cozied its way onto illuminated flat-screens.
Continued on following page
Going from " steam gauges " to " glass panel " started with the panel
mounting of a hand-held GPS.
