(2) Engage the pilot in COMPS (compass) mode. (3) AT A SPEED NOT EXCEEDING 15 KNOTS, make at least 6 large course changes of at least 100o, by multiple presses of the 10o course change buttons on any Pilot Display or Hand-held Controller. This enables the autopilot to learn the rudder gain value.
B&G Hydra & Hercules User Manual Part 3 - Commissioning and Calibration (5) Observe the performance of the autopilot when changing course. The rudder gain value is inversely proportional, therefore, if the rate of turn is too SLOW, REDUCE the value of rudder gain and the Pilot will use more rudder. If the rate of turn is too FAST, INCREASE the value of rudder gain and the Pilot will use less rudder. (6) Adjust the Rudder Gain to give an average rate of turn of approximately 6o to 8o per second.
B&G Hydra & Hercules User Manual Part 3 - Commissioning and Calibration 3.4.14 Boat Lag Value Boat Lag is the time taken for the boat to respond to changes in helm.
