What should a pilot do when conducting an Overlay approach?

When conducting an Overlay approach, it is crucial for the pilot to reference both GPS and traditional Navigation Aids (NavAids). This ensures enhanced situational awareness and cross-checking of navigation information, contributing to a safer approach. Overlay approaches rely on GPS, but they are designed to be integrated with existing procedures that utilize local NavAids.

Using both systems allows for verification of position and altitude, helping to mitigate potential navigation errors. By cross-referencing data from the GPS with that from traditional NavAids, pilots can ensure that they are following the correct flight path and maintaining situational awareness throughout the approach. This practice is particularly important in any situation where GPS may not be functioning as expected, ensuring that pilots have a reliable backup in the form of traditional NavAids. Therefore, incorporating both elements into the navigation process during an Overlay approach is essential for safe operation.
