Warren Alexander 1151793 Posted August 9, 2010 at 06:18 PM Posted August 9, 2010 at 06:18 PM Hey Guys I'm just wondering why the AIRAC goes out of date. In real life flying, do they change or modify it for security reasons? If you were doing a Hedly1 dept from Miami, for example, why would that change or go out of date? Are waypoints simply added to make flying easier or shorter? Thanks > W Link to comment Share on other sites More sharing options...

Steven Caffey Posted August 10, 2010 at 06:03 AM Posted August 10, 2010 at 06:03 AM As Ernesto said, procedures are up-numbered when a part of the procedure changes (example: the LOOP4 just became the LOOP5). As for the AIRAC cycles, the reason for them having effective and expiration dates is basically for standardization. It keeps everyone on the same page, and ensures that everyone has current information.
