Terra's TRI-NAV Indicator is different from most other Indicators. Instead of delicate meter movements, the TRI-NAV uses rows of lights for both VOR/LOC and Glideslope deviations. The more lights displayed, the greater a correction is needed. The result is easy to read and reliable.
The TRI-NAV may be connected to two NAV Receivers, allowing the pilot to toggle between them.
The TRI-NAV features:
- Gas discharge display
- Test function
The TRI-NAV is designed to be used with the following equipment:
- Terra TN-200 NAV Receiver
- Terra TN-200D NAV Receiver
