AirNavCAD presents a comparative analysis of Authorization Required (AR) approaches and VNAV procedures within the PANS OPS framework and ICAO regulations. The study examines differences in RNP navigation requirements, protection surface definition, geometric design criteria, and obstacle assessment. This technical comparison allows for an understanding of the operational and regulatory implications of each procedure type, optimizing the design of instrument approaches in specialized aeronautical CAD environments.
