OROCA's provide _____ Obstacle and _____ Mountain Clearance with no Guarantee of NAVAID reception

• A. 1000', 2000'
• B. 2000', 1000'
• C. 500', 1500'
• D. 1500', 2500'

Answer: (A)

Off-route obstacle clearance altitudes are what OROCA provides. They set safe vertical margins to keep you clear of obstacles when you’re flying away from published routes, with two different categories: in non-mountainous areas the clearance is 1000 feet, and in mountainous terrain it’s 2000 feet. It’s important to note these protections are only for obstacle clearance and do not guarantee reliable reception of NAVAIDs, so you can’t rely on radio navigation when using OROCA for planning or altitude selection.
