Just wondering when what the AIRAC cycle update schedule is? or does it us an existing format that Navigraph already have that can be used with TOPER??

Dear William,

AIRAC cycle is expected to be updated around every 6 months or so. If you need to update certain airport/s it can be done by simply editing the database file in a text editor such as notepad. If this is the case and you need any assistance, I will gladly help out.

TOPER uses customized database files which cannot be updated using navigraph packages. AIRAC cycles are updated every month, but they contain information that extends beyond the airport it self (SID, STAR, airway...). I don't expect any major changes to airport runways in periods of every 6-8 months.

Hi Nikola,

I purchased the TOPER B737NG calculator, then upgraded to 1.9.5. I see that the AIRAC is 1502, when or how can this be updated to a cycle in the 1700 series?
