What is the navigation range given by MOCA?

The Minimum Off-Route Navigation Accuracy (MOCA) is a navigation reference that defines the minimum altitude required to ensure navigational signals are received within a specified range. When it comes to the navigation range provided by MOCA, it offers a range of 22 nautical miles from the reference point, which is typically the station associated with the navigation aid.

In the context of instrument flying, MOCA is particularly crucial as it guarantees adequate signal coverage while ensuring obstacle clearance. This means that while flying at or above the MOCA, pilots can rely on their navigation systems for effective route management, knowing they are receiving accurate data for at least 22 nautical miles along the airway.

Understanding the correct navigation range associated with MOCA helps pilots maintain situational awareness and safety while navigating under instrument flight rules (IFR).
