Which VOR hosts the MOCA?

• A. V18
• B. BLE
• C. KTVR
• D. V535

Answer: (D)

MOCA is the altitude on enroute charts that guarantees obstacle clearance within about 22 nautical miles of a VOR that provides DME (a VOR/DME or VORTAC). Because you need distance information to determine whether you’re within that 22 NM zone, the MOCA is tied to the VOR that has DME. In this airway context, the VOR that hosts the MOCA is the one equipped with DME for that segment, which is V535. The other VORs listed do not serve as the MOCA host for this segment.
