Chapter 2: Using the Wheel Pilot
Manual track acquisition
If your navigator only provides cross track error information, you
must acquire the track manually:
1. Steer the boat to within 0.1 nm of track.
2. Bring the heading to within 5° of the bearing to the next waypoint.
3. Press AUTO .
4. Press -10 and +10 together to enter Track mode:
Manual track acquisition at low speeds
Using manual acquisition at low speeds requires additional care as
tidal streams have a far more significant effect at lower speeds than at
higher speeds.
In general terms, if the tidal flow is less than 35% of the boat's speed,
you will not notice any difference in the wheel pilot's performance in
Track mode. However, you should take extra care during manual
acquisition, as follows:
•
•
• the autopilot will start tracking to the waypoint
• the display will alternate between cross track error and the
locked pilot heading
before you select Track mode, make sure that the boat is as close
as possible to track, and that the direction made good over the
ground is as close as possible to the direction of the next waypoint
positive checks of the boat's position at regular intervals are vital,
especially if you are close to potential navigational hazards
