Typowe problemy
- Heading sensor (gyrocompass/GPS compass) interface faults causing erratic autopilot behavior
- Rudder feedback unit misalignment causing a steering offset
- Control panel display or backlight failures
- Software/parameter settings lost after a power interruption if backup memory fails
- Changeover between autopilot, manual, and non-follow-up modes not functioning cleanly
- Alarm system not annunciating on loss of heading signal
Lista kontrolna przeglądu
- Verify heading sensor input against the magnetic/gyro compass
- Check rudder feedback unit alignment against the actual rudder angle indicator
- Test changeover between autopilot, hand steering, and non-follow-up modes
- Test all alarm functions - off-course, power failure, sensor failure
- Check backup power supply/battery condition
- Confirm control panel and display function, including backlight
- Verify performance mode settings are appropriate for the vessel and sea state

Typowe interwały dla tej klasy konstrukcji, nie dane producenta dla Twojego modelu. Wiążąca jest instrukcja producenta.
Typowe granice zużycia
| Rudder feedback offset | should track true rudder angle within the tolerance stated in the maker's manual - not a generic figure across systems |

Krytyczne części zamienne
- Control panel unit
- Rudder feedback (angle transmitter) unit
- Backup battery pack
- Interface/comparator board, if the system is modular
Bezpieczeństwo
- Loss of steering control while underway - crew must be drilled on immediate changeover to manual/emergency steering
- A false or delayed alarm on sensor failure can mask a developing steering fault
- Do not disable alarm functions to silence nuisance alarms without addressing the underlying fault
Przegląd klasyfikacyjny
Autopilot/heading control systems interfacing with steering gear fall under SOLAS V/19 and the steering gear testing requirements of SOLAS V/26 - class/flag verifies changeover to manual steering and alarm functions at each steering gear test before departure and at periodic survey; keep test log records available.
Szacowana trwałość: Electronic control units are typically rated for continuous service over 10-15+ years with component-level repair/replacement rather than a running-hour life figure; battery and mechanical interface parts are the practical wear items.
