Is GPS usable for conducting an NDB approach?

Is GPS usable for conducting an NDB approach?

• A. Yes, always
• B. No, it cannot be used
• C. Only with advanced GPS systems
• D. Yes, but only if authorized by ATC

Answer: (B)

When considering whether GPS can be used for conducting an NDB (Non-Directional Beacon) approach, it is important to understand the fundamental differences and functionalities of the two navigation systems. An NDB approach is specifically designed to utilize signals emitted by ground-based NDBs, which provide directional guidance for the aircraft in relation to the beacon. GPS, on the other hand, is a satellite-based navigation system that operates independently of ground-based navigational aids, such as NDBs. While GPS can be used to supplement navigation and provide situational awareness during flying, it does not directly support or conduct an NDB approach. The procedure is designed to rely exclusively on signals from the NDB, making GPS unsuitable for this type of operation. Therefore, GPS cannot be utilized for conducting an NDB approach as it does not align with the requirements set forth in standard operating procedures for NDB approaches. This distinction is critical for pilots to understand in order to properly follow navigational guidelines and maintain situational awareness when flying instrument approaches.
