How may an aircraft operate in North Atlantic Minimum Navigation Performance Specifications airspace with less than the required navigation capability?

In order to operate in North Atlantic Minimum Navigation Performance Specifications (MNPS) airspace with less than the required navigation capability, the correct course of action is to request a deviation from the Administrator. This process acknowledges that the aircraft does not meet the specified requirements for navigation performance and allows for special consideration on a case-by-case basis.

The intent behind this requirement is to maintain the high safety standards and operational efficiency that MNPS airspace mandates, which includes the precise navigation capabilities necessary to avoid potential conflicts and enhance aircraft separation. When deviation is requested, it often involves an assessment of the specific circumstances, the type of operation, and the safety implications of allowing an aircraft with lesser capabilities to enter this airspace.

Operational tests and using non-standard flight paths are not standard procedures for gaining access to MNPS airspace under these conditions and could compromise safety. Similarly, obtaining special permission from the crew does not align with established regulatory procedures as it circumvents the necessary approval process through aviation authorities. Therefore, requesting a deviation is the proper protocol to follow when navigating under such constraints.
