ACN/PCN Calculator The Ultimate Pavement Strength Tool for Aviation Professionals The ACN/PCN Calculator is your go-to app for evaluating the bearing strength of airport pavements, designed specifically for pilots, flight operations engineers, dispatchers, and airport operators. Whether you’re dealing with flexible or rigid pavements, this app ensures precise calculations to verify safe operations on runways, taxiways, and aprons. By leveraging the ICAO ACN/PCN method, as outlined in Annex 14 and Document 9157 Part 3, the calculator simplifies complex computations, helping you determine the maximum allowable aircraft weight with confidence. Why Choose the ACN/PCN Calculator? • Comprehensive Aircraft Database: Data is sourced from manufacturers’ publications, including the Aircraft Characteristics for Airport Planning (ACAP) manuals. Where necessary, ICAO-recommended methods or alternative sources ensure accuracy. • User-Friendly Design: Optimized for iPhone 8+ screens and fully compatible with iPads, the interface is intuitive and easy to navigate.
