Can you perform an NDB approach using GPS?

The ability to perform an NDB (Non-Directional Beacon) approach using GPS is indeed possible and is supported by certain regulations. GPS technology can facilitate approaches by providing lateral guidance to the pilot, even for NDB approaches, which traditionally rely on analog navigation techniques.

Modern GPS systems can support the overlay of NDB approaches by providing waypoints that correspond to the NDB's location and the associated missed approach procedures. As a result, pilots can utilize GPS to navigate to an NDB approach while simultaneously following the guidance that may be augmented by the GPS system.

It’s essential for pilots to be familiar with the specific capabilities of their GPS units and ensure they have the necessary procedures in their navigational databases. Moreover, while performing the approach, pilots must adhere to the relevant regulations and guidance from the appropriate authorities, which allow the use of GPS for executing these types of approaches under the right conditions.

Understanding the integration of GPS with traditional navigation aids improves situational awareness and enhances accuracy in navigation, which is a vital aspect of instrument flying.
