Which airway has a MOCA?

Which airway has a MOCA?

• A. V535 (2,000')
• B. V18 (5,000')
• C. V74 (1,000')
• D. V427 (3,000')

Answer: (A)

MOCA is the altitude on an IFR low enroute chart that guarantees obstacle clearance along a route, but only within 100 nautical miles of the VOR used to compute it. If you’re farther from that VOR, MOCA isn’t guaranteed, and you rely on higher minimums like the MEA. In this set, the airway that shows a MOCA value on the chart is the one labeled V535, with a MOCA of 2,000 feet. That indicates this segment provides the required obstacle clearance within 100 NM of its defining VOR. The other airways list their standard minimum altitudes (like MEA) without the MOCA designation, so they aren’t MOCA airways.
