Final answer:
The MDA and visibility criteria are the minimum altitude and required visibility a pilot must meet to land on RWY 33, as specified in the instrument approach procedure charts for that runway.
Step-by-step explanation:
The MDA (Minimum Descent Altitude) and visibility criteria for landing on a specific runway, such as RWY 33, refer to the minimums a pilot must adhere to during an instrument approach. The MDA is the lowest altitude, expressed in feet above sea level, to which descent is authorized on the final approach segment of a nonprecision approach (such as a VOR or NDB approach) until the pilot sees the required visual references for the runway. Visibility criteria are the required visibility distance that must be present before a pilot can continue from the approach to the landing phase. These minimums are typically outlined in the instrument approach procedure charts for the specific runway and are determined based on various factors including obstacle clearance, navigational aid capabilities, and surrounding terrain.
