Active Passage Plan

A voyage plan in its execution phase, with the planned route loaded into ECDIS and monitored leg by leg against cross-track-error limits, safety contours, and no-go areas. SOLAS Chapter V Regulation 34 and IMO Resolution A.893(21) require passage planning in four stages: appraisal, planning, execution, and monitoring; the active plan is the execution and monitoring stages, where the bridge team watches XTE alarms, depth, and look-ahead checks against the activated route. Security overlays add HRA boundaries, reporting points, and citadel-transit timing.
