How do you maintain course when using an NDB for navigation?

When navigating using a Non-Directional Beacon (NDB), maintaining course effectively involves flying a heading that is estimated to keep the aircraft on the selected course. This method relies on understanding the relationship between the aircraft's heading and the bearing to the NDB to ensure that the aircraft remains aligned with the intended track.

Due to factors like wind drift, it is uncommon for the aircraft to fly a precisely direct heading towards the NDB. Instead, pilots must anticipate the drift caused by winds and adjust their heading accordingly. This estimation is crucial because it allows the aircraft to compensate for any deviations that might occur from the wind's effect, ensuring that the aircraft remains on the desired path.

This method of navigation allows for more accurate and reliable course maintenance, as it takes into account the dynamic environmental conditions that might affect the aircraft’s trajectory.
