Heading Control System · Autopilot & Bridge Systems
ComNav HD50 is a marine autopilot or heading-control system. It is normally installed on the bridge with interfaces to the gyro or heading sensor, steering gear and navigation controls. Its primary purpose is to command steering corrections that maintain a selected heading or track-related steering objective. Compared with manual steering, the system closes an automatic control loop using heading feedback and steering commands and therefore depends on correct sensor, rudder and control tuning. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Verify heading input, rudder feedback, mode selection, steering response, alarms and changeover to manual steering. Check interfaces to gyro, steering gear and navigation systems. Review unexpected rudder activity or fault history. Exact tuning parameters and acceptance tests require manufacturer and vessel documentation.
Carry fuses, control relays, heading or rudder-interface modules, operator controls and backed-up configuration information where supported.
