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.

Verdict
The clearest difference is review sentiment: TBM Performance at 88% against ACN/PCN Calculator's 45%. TBM Performance also leads on in-app purchases (none vs 26) and rating (5.0 vs 4.6). ACN/PCN Calculator's advantage is ads (none vs shown) and ratings volume (142 vs 14). On price, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ACN/PCN Calculator sells 26 one-off in-app purchases. TBM Performance asks for nothing beyond the download.
TBM Performance holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ACN/PCN Calculator has 142 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 88% of TBM Performance's written reviews are positive against 45% of ACN/PCN Calculator's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on July 23, 2026 and August 13, 2026 respectively.
