Common Question of Simrad AP44 VRF
What does the AP44 VRF pack include?
The Simrad AP44 VRF High Capacity Autopilot Pack is an autopilot package for compatible high-capacity steering systems. Confirm included drive, processor, feedback method, heading source, display, wiring, battery, and marine autopilot controller compatibility before installation.
What does VRF mean?
VRF means Virtual Rudder Feedback, a system method that can estimate steering position in compatible installations without a conventional rudder sensor. Confirm supported drive, calibration procedure, software, network wiring, and vessel requirements before commissioning.
Does it control a windlass?
No. The AP44 VRF pack manages autopilot steering and does not operate a gypsy, drum, chain, or anchor rope. It is not an anchor windlass component. Verify separate equipment for marine anchor retrieval.
