The eNASR Browser lets you browse NASR data sets, including:
- Current cycle
- Next cycle
- PreChart cycle
- Next cycle information is a preview of the next effective AIRAC cycle. The information could be changing daily until the cutoff for that cycle, 34 days before the effective date.
- PreChart cycle information could be changing daily. It should not be considered as definitively part of a current or future AIRAC chart cycle. It should not be used for navigation or flight planning. It will reflect changes published in the National Flight Data Digest (NFDD).
