The tiller pilot displays the cross track error in the following ways:
2 Using the Tiller Pilot
On track
Off track to port (steer to starboard)
Off track to starboard (steer to port)
Tidal stream compensation
Under most operating conditions, Track mode will hold the selected track to within ±0.05 nm (300 ft) or better.
The autopilot takes account of the boat’s speed when computing course changes to ensure optimum performance over a wide range of boat speeds. If speed data is available, the autopilot will use the measured boat speed. Otherwise it will use the default cruise speed entered in Calibration Level 5 (see page 64).
