Hi…,

Welcome.

As per [FAQ - Previous Navigraph AIRAC Cycles](https://forum.navigraph.com/t/faq-previous-navigraph-airac-cycles/127), we don’t provide previous AIRAC Cycles.  
Your best option is to take an Ultimate Monthly subscription, download the Navigation Data for SimBrief and the aircraft you have, try out Charts, then if don’t wish to renew, cancel the subscription before the month expires.

Compliments of the Season.

Ian
