Learning to Fly the NDB

Like driving a stick shift on a car, the non-directional beacon (NDB) approach is a handy skill for pilots.

Key Takeaways:

NDB approaches, while an older and increasingly rare technology, remain relevant for instrument pilots, appearing on check rides and serving as a crucial backup navigation method.
The article details the basics of NDB (ground transmitter) and ADF (aircraft receiver) systems, explaining how the ADF needle indicates bearing to the station and providing techniques for calculating magnetic bearing and making wind corrections during an approach.
It highlights the limitations of NDB navigation, such as susceptibility to terrain, night fluctuations, precipitation static, and shoreline refraction, but emphasizes that mastering these approaches provides a unique and valuable skill set for pilots.

Do you know how to fly a non-directional beacon (NDB) approach using an automatic direction finder (ADF)? Could you teach someone how to do it?

Before you go off on the “new and better technology” available to instrument pilots, no one is disputing that. But the fact is that NDB approaches, while increasingly rare, are still out there. And there are still airplanes equipped with ADFs that enable the pilot to fly these NDB approaches—if only someone taught them how.
