Off-Route Obstruction Clearance Altitude (OROCA)

January, 2, 2021 by

An off-route obstruction clearance altitude (OROCA) is an off-route altitude that provides obstruction clearance with a 1,000-foot buffer in non-mountainous terrain areas, and a 2,000-foot buffer in designated mountainous areas. This altitude doesn’t guarantee signal coverage from ground-based NAVAIDs, ATC radar, or communications coverage. It can be seen here on this IFR low chart.
