Type NT920RAI

Navitron Rudder Angle Indicators (type NT920RAI) can be configured for single or multi head display as add on components to all Navitron autopilot types or as independent (stand alone) systems employing a dedicated Rudder Angle Transmitter Unit (NT920RTU).

Note 1: Where a Navitron autopilot and NT920RAI(s) are installed and the latter are required to function independently of the autopilot system, a Dual Rudder Reference Unit (DRRU) can be employed to eliminate the need for two separate transmitter units at the rudder stock:

Where an independent Rudder Indicator system only is required:

All Indicator heads (NT920RAI) are electrically and mechanically identical (no master / slave distinction) which provides complete interchangeability and straightforward system expansion.

Each Indicator head comprises a robust centre zero moving coil driving an illuminated white pointer against a black scale background graduated in 5° increments. Provision is also made for fixed and variable intensity red backlight scale illumination for night viewing.

Standard RAI heads are suitable for wheelhouse (sheltered) panel mounting. External locations may be used (foot bracket or panel mount) when supplied with a Navitron Pod assembly (PM).
