Sandia SAC 7-35 Air Data Computer



Sandia SAC 7-35 Air Data Computer - four systems in one.

Sandia SAC 7-35 contains an altitude encoder, altitude alerting, fuel flow, and air data computer.

SAC 7-35 is an FAA TSO-approved altitude encoder that provides RS-232 for newer generation transponders as well as standard Gilham Grey code for legacy transponders. The system is also equipped with SANDIA’s altitude inflight monitoring (AIM) which alerts pilots whenever the aircraft deviates 100 feet or more from the selected altitude. When paired with a fuel flow transducer, the SAC 7-35 provides all the fuel flow data required for navigation systems to monitor fuel flow.

The SAC 7-35 is also a fully TSO’s airdata computer with multiple interface formats that provide data to a wide variety of avionics systems.

SAC 7-35 Air Data Computer includes tray connectors, OAT probe, and install manuals.
