MOCA's provide ___ NM of NAVAID reception between NAVAIDs while having ______' Obstacle and ______' Mountain Clearance

MOCA's provide ___ NM of NAVAID reception between NAVAIDs while having ______' Obstacle and ______' Mountain Clearance

• A. 22 NM, 1000', 2000'
• B. 22 NM, 2000', 1000'
• C. 20 NM, 1000', 2000'
• D. 25 NM, 1000', 2000'

Answer: (A)

MOCA guarantees you can receive the NAVAID signal out to a specific distance on enroute segments, and it also sets minimum clearance requirements for obstacles along the route. The reception distance is 22 nautical miles from the VOR between VORs, which is the span where the MOCA signal is assured. The clearance values reflect the safety margins: 1000 feet of obstacle clearance in general terrain, and 2000 feet of mountain clearance to account for higher elevations in mountainous areas. So the best pairing is 22 NM of NAVAID reception with 1000 feet of obstacle clearance and 2000 feet of mountain clearance.
