*) The track control system is able to compensate drift up to 45 degrees. If the drift is larger, your ship may go
outside the channel limit..
**) The track control system is able to compensate cross-track error up to 30 degrees. However, the full
compensation is not available immediately. Two alarms will warn the operator if the track control system estimates
that it is not able to keep your ship within channel limits. Alarm "519 Trackpilot: XTE comp. limit" informs you that
no further cross-track error based compensation is possible. Alarm "455 Route: Off course" informs you that the
track control system cannot use a higher attack angle towards the track.
