Explanation of Changes

Effective: November 3, 2022

  1. General Information—Aeronautical Information Manual (AIM) Code of Federal Regulations and Advisory Circulars This change removes the reference to the canceled Advisory Circular (AC) 00-2 in the Aeronautical Information Manual (AIM), General Information-Code of Federal Regulations and Advisory Circulars section. It also adds a note, with a link, that sends users where current AC information can be found.
  2. 1-1-9. INSTRUMENT LANDING SYSTEM (ILS) This change amends the Aeronautical Information Manual (AIM), 1-1-9 Instrument Landing System (ILS), subparagraph k, ILS Course Distortion, correcting deficiencies in the paragraph and better aligning content with that published in FAA Order JO 7110.65, paragraph 3-7-5. This change also adds controller observation and PIREPs to the sources contributing to the official weather observation.
  3. 1-1-17. GLOBAL POSITIONING SYSTEM (GPS)
    7-6-7. MOUNTAIN FLYING
    This change provides pilots guidance on the use of visual flight rules (VFR) waypoints for mountain pass entry points.
  4. 3-2-3. CLASS B AIRSPACE
    3-2-4. CLASS C AIRSPACE
    4-1-8. APPROACH CONTROL SERVICE FOR VFR ARRIVING AIRCRAFT
    4-1-18. TERMINAL RADAR SERVICES FOR VFR AIRCRAFT
    4-4-11. IFR SEPARATION STANDARDS
    4-5-3. SURVEILLANCE RADAR
    5-4-11. RADAR APPROACHES
    This change will eliminate the reference to Center Radar Presentation (CENRAP) in several paragraphs in the AIM.
  5. 3-5-2. MILITARY TRAINING ROUTES This change to subparagraph 3-5-2e clarifies that Military Training Route (MTR) information from the Flight Information Publication (FLIP) is available through Flight Service. This change also adds a new subparagraph f that provides specific information for accessing MTR route information from the FAA. In addition, the former subparagraph f was re-lettered g and “while inflight" was added for clarification.
  6. 4-1-9. TRAFFIC ADVISORY PRACTICES AT AIRPORTS WITHOUT OPERATING CONTROL This change updates the AIM to incorporate the changes to the FAA Advisory Circular, AC90-66B, that address pilot recommended self-announce broadcasts along with recommendations for pilots conducting straight-in landings to non-towered airports. This change also adds the reference to the AC 90-66, Non-Towered Airport Flight Operations.
  7. 4-1-18. TERMINAL RADAR SERVICES FOR VFR AIRCRAFT This change adds the word “participating" and “and other participating VFR" in subparagraph 4-1-18b6 to clarify that the guidance only applies to participating visual flight rules (VFR) aircraft.
  8. 4-1-20. TRANSPONDER AND ADS-B OUT OPERATION
    4-4-15. USE OF VISUAL CLEARING PROCEDURES
    This change expands the language in AIM paragraphs 4-1-20 and 4-4-15 to include the limitations inherent in visual scans for traffic and the benefits and best practices of using cockpit displays of traffic information to supplement visual scans to help overcome these limitations.
  9. 4-5-1. RADAR This change adds information to raise awareness regarding potential limitations on Air Traffic Control (ATC) radar for aircraft flying in the vicinity of wind turbine farms and expands the knowledge of pilots regarding the effects on aviation safety.
  10. 4-7-1. INTRODUCTION AND GENERAL POLICIES This change replaces “West Atlantic Route System" with “West Atlantic" in the title of the referenced Resource Guide for U.S. Operators.
  11. 5-4-5. INSTRUMENT APPROACH PROCEDURE (IAP) CHARTS
    5-4-9. PROCEDURE TURN AND HOLD-IN-LIEU OF PROCEDURE TURN
    7-3-6. EXAMPLES FOR CALCULATING ALTITUDE CORRECTIONS ON CTAS
    This change has updated the referenced instrument approach procedures (IAPs) due to the FAA Order 8260.19 update to remove the requirement to those references from the profile notes, and to add explanatory language that altitude restrictions at stepdown fixes in the final approach segment are not applicable to instrument landing system (ILS), Localizer Performance with Vertical Guidance (LPV), or LNAV/Vertical Navigation (VNAV) approaches.
  12. 5-4-23. VISUAL APPROACH
    5-5-11. VISUAL APPROACH
    This change adds content to address go-around responsibilities after conducting a visual approach for aircraft either instructed to remain within the traffic pattern or proceed as otherwise directed by air traffic control (ATC). This change also addresses the difference in approach clearances for locations with or without an operating control tower.
  13. 7-1-10. WEATHER OBSERVING PROGRAMS This change clarifies that wind direction is reported relative to magnetic north in the Automatic Terminal Information Service (ATIS) as well as the Automated Surface Observation System (ASOS) and the Automated Weather Observation System (AWOS) broadcasts.
  14. APPENDIX 4. FAA FORM 7233-4. INTERNATIONAL FLIGHT PLAN This change removes existing instructions allowing alternate use of NAV/ to indicate Area Navigation (RNAV) capability to resolve incompatibility with required navigation performance (RNP) routing. Adds instructions for RNP Standard Instrument Departures (SIDs) and Standard Terminal Arrival Routes (STARs), which are being added to the NAS (for example, see the KSNA STAYY SID). Removes the legacy use of NAV/ for RNAV capability to avoid the NAV/ information overriding RNP capability filed in PBN/. Because ICAO guidance is moving towards use of standardized, unambiguous codes M1 and M2 for the two variations of RNP 2, the information relating to Australia's practice is removed from the table.
  15. Editorial Changes Editorial changes include defining PIREP consistently as Pilot Weather Report and fixing incorrect references in paragraph 5-6-6.
  16. Entire Publication Additional editorial/format changes were made where necessary. Revision bars were not used because of the insignificant nature of these changes.
