What is the primary function of the OROCA?

The primary function of the OROCA, or Off-Route Obstruction Clearance Altitude, is to ensure vertical separation from obstructions in the airspace. It provides pilots with a predetermined altitude that guarantees a safe distance from terrain and other obstacles when flying off established routes. This is particularly important in areas where there may not be specific navigational aids or route guidance available, as it helps in maintaining safety by offering a reliable altitude to avoid potential hazards.

The focus on vertical separation highlights the necessity of awareness of terrain and obstructions, enabling pilots to navigate safely even when they are not on traditional airways. By having the OROCA information, pilots can make informed decisions regarding their altitude, thus contributing to safer air operations.
