We have a strong affection for the folks at Sandia Aerospace...
a little company that plugs along building great gear with not
nearly enough fanfare... and providing excellent values, to boot.
Sandia Aerospace was founded in 1997 by a group of avionics
professionals to provide high quality avionics products to General,
Corporate and Regional airline markets.
Major product offerings include the company's SAE 5-35 Altitude
Encoder, SAC 7-35 Airdata Computer, Avionics Cooling Fans,
and MARC 70 interface modules. Sandia products are offered
worldwide by both avionics modification centers and aircraft
Now, the Albuquerque, New Mexico company is branching out into a
line of its own products, starting with the STX-165 Transponder,
which is debuting at AirVenture at Oshkosh. The STX 165 Sports a
professional 1/2 3ATI Bezel that compliments any aircraft
panel. Its bright OLED display is readable in virtually all
lighting conditions and automatically dims for night time
Built-in Encoder -- Simplifies installations and lowers
Three Timer Functions -- Elapsed Flight Time, Up Timer, Down
Pressure Altitude Display -- See what altitude your transponder
is reporting to Center
