How often does APG refresh the OEM (AFM) data within iPreflight Genesis?

 APG maintains a subscription service that supports all current production aircraft models and many out-of-production models. While instrument procedures and obstacle data are typically refreshed every 28 days in alignment with standard aviation data cycles, OEM Aircraft Flight Manual (AFM) data is updated on an as-needed basis. Specifically, APG updates the OEM AFM data whenever the aircraft manufacturer (OEM) publishes new or revised data.
