Off-Scale Danger Course Indicator
The indicator displays point and area charted navigational hazards on a course scale. The monitoring sector is always oriented to the ship’s COG.
Navigational hazards are always displayed on the indicator regardless of whether navigational hazard highlighting on the ENC is enabled or disabled.
