NT850 Main Steering System – Type 3

Dual Independent Rudder Systems benefit from simple synchronisation of rudder positions (when required) via inclusion of the NT850 NFU and immediate Override control is available to the operator in any emergency situation via use of the NT850 OVSW. Steering Mode and Pump selection is afforded by the NT850 STMS and NT850 STSS respectively (as shown above) to provide the required Steering Mode (Follow Up, Non Follow Up or Autopilot) plus selection of the Rudder System to be used (No 1, No 2 or both) plus Pump Selection (2 per rudder system) to allocate/share duties/redundancy as required.

Operation is therefore straight forward with operating/control modes defined as follows:
FU ……. Follow Up Wheel unit type NT850 WFU active.
NFU …. Non Follow Up control type NT850 NFU active.
Auto … Propietary Autopilot Steering active.
