OPTION 1 for the AOPA Sweepstakes

Grumman Tiger includes two
Garmin G3X Touch flight displays
(10 inch and 7 inch), a G5 backup attitude indicator, a GSB 15
USB charger, and a center stack
containing a GMA 245 audio panel,
GNX 375 GPS navigator and ADS-B
transponder, GNC 255 back-up nav/
com radio, and GMC 507 autopilot
control panel. This setup requires
a new instrument panel be cut to
mount the avionics.
OPTION 2 retains the original instrument panel and includes four GI 275
electronic flight instruments
(attitude indicator, horizontal
situation indicator, engine indication
system, and multifunction display).
This option mounts two GSB 15s
in unused instrument cutouts and
adds a GTR 200 back-up com radio
to the center stack.

THE SKELETAL REMAINS of the Tiger's instrument panel will soon be cut out of the aircraft.

The glareshield has already been removed. J.A. Air Center will fabricate a new panel and
glareshield to house the Tiger's glass cockpit.

HOW WOULD YOU MODERNIZE an instrument panel on a 43-year-old airplane?
There are many avionics upgrades available
for general aviation aircraft, ranging from
a single electronic flight instrument (say,
an attitude indicator) to a full glass cockpit makeover. We consulted with Garmin
on options for the AOPA Sweepstakes
Grumman Tiger and narrowed our choices
down to two: retrofitting the existing panel
with a four-pack of Garmin GI 275 electronic flight instruments; or installing an
entirely new instrument panel to create a
glass cockpit featuring Garmin G3X Touch
flight displays.
Some pilots are not convinced a glass
cockpit is for them; they prefer the familiarity of analog gauges but appreciate the
advanced capabilities of electronic flight
displays. Others just don't need an entire
glass cockpit upgrade. In these situations,

32 | AOPA PILOT June 2021

replacing one or more analog gauges with
Garmin GI 275s may be the logical choice.
GI 275s match the form factor of 3-1/8inch round analog gauges. The ability to
easily swap out analog gauges for digital
instruments fosters panel upgrade flexibility in most older airplanes. You can start
by upgrading what is arguably your most
critical instrument: the attitude indicator.
By doing so, you gain increased situational
awareness and remove one link from the
vacuum pump failure chain-while adding the security of an optional 60-minute
battery backup. Add a few more GI 275s
(horizontal situation indicator, engine
indication system, and multifunction display versions are also available), and you
have much of the functionality of a glass
cockpit with minimal disruption to your
existing instrument panel. Add more than
two or three GI 275s, however, and your
