Know instantly whether your aircraft can safely operate on a given pavement. ACR/PCR & ACN/PCN — one tool, one answer.
Free to download · Core features available for testing
Instant, reliable pavement strength assessment — ACR/PCR and ACN/PCN in one tool.
Both modern and legacy pavement classification systems in one tool
Comprehensive database — Boeing, Airbus, Embraer, Bombardier, and more
Displays the ICAO overweight reference value alongside the standard maximum weight. Overweight operation remains subject to airport/operator approval, pavement condition, frequency of operation, and applicable regulation.
Generate shareable calculation reports with full aircraft and pavement details
Creating valid PCR and PCN codes manually is slow and error-prone — especially under operational pressure.
The Composer is a purpose-built input system that only allows valid entries at each step — ensuring correct codes in seconds.
A real calculation result — from aircraft selection to operational decision.
Many airports still report pavement strength using the legacy PCN system — switch between ACR/PCR and ACN/PCN with a single tap.
Verify aircraft pavement compatibility during flight preparation at any airport.
Integrate weight limit checks into flight planning workflows — via app or REST API.
Perform airport suitability and pavement compatibility checks with confidence. Access ACR/PCR and ACN/PCN data using one practical tool.
Evaluate runway strength requirements against traffic mix. PCR vs. ACR analysis on demand.
Choose from 250+ ICAO aircraft types — Boeing, Airbus, Embraer, and more. All data verified against official publications.
Compose the pavement classification rating/number from NOTAM or AIP. Supports flexible/rigid pavements, all subgrades, and tire pressure categories.
Maximum allowable weight, ICAO overweight reference value, and the minimum ACR or ACN for any given weight.
Building a dispatch platform, EFB integration, or flight-ops system? Add ICAO-compliant aircraft-pavement weight limits directly into your workflow via a lightweight REST API. Two endpoints cover everything: aircraft lookup and weight-limit computation. Authentication is API-key based.
Contact us to receive API credentials and full documentation. JSON in, JSON out.
The API is currently under development and operational testing, with company access planned for the near future. API access is available for companies and organizations only, not individual accounts.
