An ADAPT authorization will be required
for flights occurring in ADS-B Out rule airspace starting at 12:01 am Eastern Standard Time on January 2, 2020.
In order to be considered for an ADS-B deviation authorization with ADAPT, requests must meet the following criteria:
- Aircraft must be equipped with an operational transponder and operational altitude encoder (e. g., Mode C)
- Request submitted no more than 24 hours before flight
- Request submitted no less than 1 hour before flight
Please note: The FAA will not issue in-flight authorizations to operators of non-equipped aircraft, nor will air traffic control (ATC) facilities accept requests for these types of authorizations by telephone.
