Reasonable people can disagree about how to fly an instrument approach, with both sides of the argument having some merit. This applies to a discussion I had with an experienced instrument flight instructor about how to descend to the minimum descent altitude (MDA) on a nonprecision instrument approach. We disagreed over two approaches to approaches. The constant airspeed technique (my recommendation) has a pilot making a descent to the MDA, leveling off, and flying to the missed approach point (MAP). If the pilot has the required visibility and identifiable runway environment, he descends and lands, but only after reaching the visual descent point (VDP).
