What to do if Simrad AP21 autopilot operates on simulated feedback?
If your Simrad Marine Equipment autopilot operates on simulated feedback due to rudder feedback failure, it means the rudder feedback signal is either missing or erratic. First, check all connections. Then, check the alignment according to the installation instructions. If the problem persists, replace the rudder feedback unit.
How to fix a slow rudder test on Simrad AP21?
If the rudder test is too slow on your Simrad Marine Equipment, it could be due to excessive load on the steering gear, air in the hydraulic system, or insufficient drive unit capacity. You should: 1. Look for mechanical obstructions at the rudder/tiller/quadrant and check the back drive force. 2. Bleed the hydraulic system. 3. Replace the existing unit with a bigger pump unit.
