Anchor Alarm
The "Anchor Alarm" will trigger (audible
and visual alert) if enabled and the position changes more then the selected
distance. "Test" can be selected to simulate the
alarm. In order for the Anchor Alarm to work, iNavX must be active (i.e. running)
and have a good position fix (as indicated by "HPE:"
in the Instruments view). The Anchor Alarm perimiter is plotted on the chart. "AAD:" in the Instruments view will display the amount of drift.
