Video Tip: Flying to an MDA with the Autopilot

Many instrument pilots are comfortable using the autopilot during an approach, but leveling off smoothly at the minimum descent altitude (MDA) on a non-precision RNAV approach requires careful planning and a good understanding of your avionics.

In this video, Bruce Williams demonstrates one technique for flying the RNAV (GPS) Runway 27 approach into Port Angeles, Washington. Using a Garmin GFC 600 autopilot, he shows how to level off at the MDA while allowing the autopilot to maintain lateral guidance, reducing workload as the airplane continues toward the missed approach point.

The technique can be useful when continuing beyond the visual descent point (VDP) while maintaining the MDA, but only if you understand how your specific autopilot operates. Bruce emphasizes the importance of practicing these procedures in VMC so you’re comfortable with your avionics before needing them in actual instrument conditions.
