Multiple Choice

OROCA's provide only ___________ clearance.

Explanation:
Off-route obstacle clearance altitude provides obstruction clearance for aircraft flying off established routes. It guarantees clearance from fixed obstacles (typically 1,000 ft in non-mountainous areas, 2,000 ft in mountainous areas) within a 4 NM corridor on either side of the route, but it does not guarantee terrain clearance. It’s a planning aid on IFR enroute charts to avoid obstacles when not on a published airway, not a guarantee against terrain.
