Effective today, January 2, 2020, pilots/operators using aircraft that do not meet ADS-B Out equipage or performance requirements may request an authorization to deviate from the rule to access ADS-B Out rule airspace.

The FAA has developed the ADS-B Deviation Authorization Preflight Tool (ADAPT) to manage these authorization requests. 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.

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.
