ADS-B Deviation Authorization Preflight Tool

After January 1, 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

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.

ADAPT Steps

View the ADAPT Tutorial Video for a step by step guide to submitting an authorization request.

Step 1

Access the ADAPT Website

Submit your authorization request no more than 24 hours and no less than one hour before your intended departure time.

Step 2

Enter Flight Details using the Flight Information Entry Form

This step checks for alternate surveillance availability based upon your proposed route of flight and aircraft avionics equipment configuration. Please note this step does not constitute filing a flight plan.

Step 3

Enter the Deviation Request and Additional Flight Details

Provide additional details describing the nature of your deviation request. You must verify your information is correct and accurate by selecting the verification checkbox or the request cannot be submitted.

Step 4

Receive Request Status

After submitting your request, you will receive an immediate automated response via the ADAPT website indicating the status of your request (Approved, Denied, Pending) followed by an official FAA email response to the request. When you receive an official email approval, you are authorized to conduct your flight.

Please note: An ADS-B deviation authorization granted using ADAPT does not equal, nor does it guarantee, an ATC clearance into airspace where ADS-B Out equipment is required.

Frequently Asked Questions

  1. Who can use the ADS-B Deviation Authorization Preflight Tool (ADAPT)?

    ADAPT is intended to be used primarily by:

    • Non-commercial General Aviation aircraft who are not equipped with ADS-B Out
    • Operators using aircraft that do not meet ADS-B Out rule performance requirements
  2. Are there any special equipment requirements to consider prior to applying for an authorization?

    Yes. Aircraft requesting an ADS-B deviation authorization must be equipped with an operational transponder and operational altitude encoder (e.g. Mode C) or the request will be denied.

  3. Is ADAPT the same thing as the ADS-B Service Availability Prediction Tool (SAPT)?

    No, ADAPT and SAPT are two different tools. However, both of ADAPT and SAPT are needed to request an ADS-B deviation authorization. SAPT provides predictions of ADS-B and/or alternate surveillance information for specific flight times and equipment configurations. Once this information is available for a specific flight, ADAPT is used to request an ADS-B deviation authorization for the proposed flight into ADS-B Out rule airspace.

    Since the ADAPT is a functionality built into SAPT, ADAPT will not function if SAPT is out of service.

  4. Can an applicant submit a request for the same aircraft more than once?

    Yes. Each request will be considered individually.

  5. How does an applicant know when a request has been approved/denied?

    A status response will be displayed on the ADAPT website within a few seconds after the request is submitted. Status indicators will be either Approved, Denied, or Pending.

    You will also receive an official FAA email with the status response.

  6. What happens if the ADAPT response is pending?

    Requests that do not meet automatic approval or denial criteria are placed into "Pending" status. Pending status requests are forwarded to an FAA air traffic control representative for manual review. These representatives are available between the hours of 6:00am and 10:00pm Eastern Time.

    In this case, you will receive an immediate automated response via the ADAPT website indicating the status of your request is Pending, followed by an official FAA email response to the request.

    A second email will be sent when a Pending request has been resolved.

    Please note that pending requests will automatically be denied if they haven't been manually processed at least 30 minutes prior to the proposed time of departure. In this case, a denial email will be sent to applicant.

  7. Will SAPT/ADAPT work on mobile devices?

    ADAPT has been tested and found functional with Internet Explorer and Chrome browsers. Though not validated, it should also work using other internet browser methods and on mobile devices.

  8. Is there an ADAPT app?

    No.

  9. What are some reasons an ADAPT request could be denied?

    An ADAPT request may be denied for a number of reasons, including:

    • Using aircraft without an operational transponder or without altitude encoding
    • Request submitted less than an hour before departure time
    • Request requires manual review but is submitted outside of the review hours (6:00am – 10:00pm Eastern Time)
    • Proposed flight to/from a capacity constrained airport
    • Proposed flight into non-surveillance areas
