What is required for an alternate airport when using GPS for navigation?

When using GPS for navigation, having an approved operational instrument approach procedure is essential for an alternate airport. This requirement ensures that the pilot can rely on a standardized and verified procedure to safely navigate and land at the alternate if the primary airport becomes unavailable. Approved procedures are published and publicly available, ensuring that they meet safety and regulatory standards.

In the context of using GPS, specific approaches could encompass various types of navigational aids, and it assures pilots they can transition to alternate airports safely, even if they solely rely on GPS systems. This reinforces the importance of planning and preparedness in aviation operations, particularly in Instrument Flight Rules (IFR) scenarios where precision and reliability are paramount for safety during flights and approaches.
