GPS Approach Overlay Program Definition
The GPS Approach Overlay Program is an authorization that allows pilots to use GPS avionics for flying existing nonprecision instrument approach procedures under IFR conditions. This program excludes the use of GPS for LOC (Localizer), LDA (Localizer Type Directional Aid), and SDF (Simplified Directional Facility) procedures. Essentially, the GPS Approach Overlay Program enhances situational awareness and offers reliable navigation for pilots to safely approach designated runways using GPS technology. The program is designed to increase the accuracy of non-precision approaches, reducing the need for ground-based navigational aids. Overall, the GPS Approach Overlay Program provides pilots with an efficient solution for instrument navigation, improving flight safety and reducing the likelihood of accidents and damages.
