The FAA recently published Change 3 of the Aeronautical Information Manual (AIM) effective April 20, 2023. The updated AIM is available now in the Sporty’s online course portal at

Change 3 updates include:

4-1-20. TRANSPONDER AND ADS-B OUT OPERATION This change adds instruction to pilots participating as the lead aircraft in a visual flight rules (VFR) standard formation flight not receiving ATC services to squawk beacon code 1203. Additionally, paragraphs have been reordered and a duplicate section has been deleted.

4-3-6. USE OF RUNWAYS/DECLARED DISTANCES This change clarifies responsibilities associated with air traffic control (ATC) selecting and/or assigning RUNWAY IN USE/ACTIVE RUNWAY/DUTY RUNWAY. This change emphasizes that tailwind and crosswind considerations take precedence over delay/capacity considerations, and noise abatement operations/procedures. This change also provides note information that explains parallel runway number markings.

5-3-4. AIRWAYS AND ROUTE SYSTEMS References and a brief description of Y routes are added in paragraph 5-3-4, subparagraph a3. These point the reader to the Aeronautical Information Publication (AIP) for detailed information on flying Y routes.

5-6-4. ADIZ REQUIREMENTS The Aeronautical Information Manual (AIM) and Aeronautical Information Publication (AIP) will be updated with the clarifying language previously added to the FDC NOTAM 2/8783, concerning the procedures and equipment required to operate into, out of, and within the Air Defense Identification Zone (ADIZ).

7-1-8. INFLIGHT WEATHER ADVISORY BROADCASTS This change removes the references to Traditional Alphanumeric Code (TAC) Airmen’s Meteorological Information (AIRMETs) over the contiguous United States. Also, it updates the description of AIRMETs and Significant Meteorological Information (SIGMETs) to better describe the products and how they are disseminated in the contiguous United States, Alaska and Hawaii.
