Heading

D3505-1

• The display shows the new bearing to waypoint.

Manual acquisition

For manual track acquisition, when only cross track error data is

available:

1. Steer the vessel 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 track to enter Track mode.

• The display shows the locked pilot heading.

Note: At low speeds, the effect of tidal streams is far more significant

than it is at higher speeds. Providing the tidal flow is less than 35% of

the vessel’s speed, no noticeable difference should occur in the

performance of Track mode. However, extra care should be taken

during manual acquisition, as follows:

• Ensure that the vessel is as close as possible to track, and the

direction made good over the ground is as close as possible to the

direction of the next waypoint, before selecting Track mode.

• Make positive positional checks at regular intervals, especially if

navigational hazards are close by.
