# Hazard Monitoring (Ground check)

Configures parameters for scanning hazards on ENC (charted hazards), highlighting them on the chart, and generating cautions within a strip whose width includes the set distance to hazards, the current positioning error (maneuvering lane), as well as in the bow and stern sectors.

The hazard detection distance is set by the navigator or calculated automatically based on the vessel's speed and the set hazard detection time.

When navigational hazards are detected within the lane occupied by the vessel, accounting for drift, position determination error, and CATZOC, an audible alarm is generated. In general, the distance to hazards set by the navigator should be greater than the automatically calculated maneuvering lane.

Navigational hazards detected in the bow sectors are displayed on the {doc}`off-scale dangerous bearings indicator </sections/graphical-user-interface/off-scale-indicators/index>`.

Navigational hazards detected in the stern sector are highlighted on the chart to monitor the safety of the vessel's turn in a narrow channel or when proceeding with significant drift.
