In the world of serious flight simulation, the Navigraph AIRAC cycle is the bible. It keeps your FMC, GPS, and moving maps in sync with real-world procedures. Every 28 days, a new cycle drops (e.g., 2410 for October 2024).
But for users of —specifically Microsoft Flight Simulator 2004 (FS9), FSX, Prepar3D (v1-3), and even legacy versions of X-Plane 11—a legend persists: AIRAC Cycle 1708 .
Modern alternatives exist: Navigraph offers a that can install only the cycles your sim needs, and they still support FSX and P3Dv3 (though not FS9). Conclusion: Is the 1708 Cheat Worth It? | For FS9 only (no online flying) | Maybe – it’s your only option | |--------------------------------|-------------------------------| | For FSX/P3Dv3 offline flying | Risky but functional | | For VATSIM/IVAO or modern simming | Absolutely not – use current data |
Happy (and legal) flying. Disclaimer: This article is for educational purposes regarding flight simulation history. The author does not condone software piracy.
