Hi All I’m new to Simbrief so I’m hoping this is a stupid question, I’ve searched but not found anything similar. Creating a new flight plan I get AIRAC outdated and it shows that I’m using 2403. When I check the available cycles 2404-2506 are showing but “Activate” is greyed out? I don’t have a navigraph subscription so expect 2507 to be unavailable but am I missing something with the others? ![airac](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/8/3/836aa23d9f1a889c8ee7d06c5f3a664df47fdce6.png) ![Screenshot 2025-08-03 151325](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/7/5/756901b48bebc5eb6aafcbc3093abaf48ea6d729.png) ---

Cycle 2403 is the latest default version, all others required a subscription and need to be activated during the cycle. ---
