The FAA recently published Change 1 of the Aeronautical Information Manual effective December 2, 2021.
- The completed Explanation of Changes Document may be accessed here.
- The updated AIM may be accessed here.
1−1−9. INSTRUMENT LANDING SYSTEM (ILS) – further clarifies the ILS Expanded Service Volume (ESV) and includes a new figure that better explains how pilots can identify an ILS ESV when consulting a charted instrument procedure.
1−1−17. GLOBAL POSITIONING SYSTEM – The NOTAM subparagraph (g) was deleted so as not to duplicate. There is a specific NOTAM paragraph (5−1−3) that explains NOTAMs in detail. A few paragraphs were moved to supplement the RAIM paragraph. Lastly, in an effort to clarify guidance and to ensure it supports what is currently being charted in regards to the missed approach waypoint (MAWP) and the missed approach holding waypoint (MAHWP), a clearer depiction and a minor correction on how Fly−by (FB) and Fly−over (FO) waypoints are used and depicted on approach charts.
5−4−5. MINIMUM VECTORING ALTITUDE (MVA) – This change rewrites the notes in off route obstruction clearance altitude (OROCA) related paragraphs, to incorporate updated terminology and enable a better understanding of how OROCA is utilized.
5−1−3. NOTICE TO AIRMEN (NOTAM) SYSTEM – GPS NOTAM and receiver autonomous integrity monitoring (RAIM) information is currently located in the overview section of the AIM/AIP. This change consolidates all of the NOTAM information into one procedures section and updates current NOTAM language. This update references how to report GPS anomalies, as well as edits two tables with example NOTAMS on GPS testing and pseudo−random satellite numbers.
5−1−17. COLD TEMPERATURE OPERATIONS – This change replaces paragraph 5−1−17 Cold Temperature Operations guidance and preflight planning information being updated to reflect the two temperature limitations that may be found on an FAA produced instrument approach procedure (IAP). The new paragraph also directs operators to Chapter 7 to review the information on cold temperature altimetry errors and current procedures for CTA and baro−VNAV temperature limitations.
5−2−7. DEPARTURE RESTRICTIONS, CLEARANCE VOID TIMES, HOLD FOR RELEASE, AND RELEASE TIMES – A recent change to FAA Order JO 7110.65 requires that ATC give a pilot departing from an airport without an operating control tower a departure release, a hold for release, or a release time when issuing the departure clearance. This AIM change reflects the change made to FAA Order JO 7110.65 and clarifies pilot and controller responsibilities.
5−2−9. INSTRUMENT DEPARTURE PROCEDURES (DP) − OBSTACLE DEPARTURE PROCEDURES (ODP), STANDARD INSTRUMENT DEPARTURES (SID), AND DIVERSE VECTOR AREAS (DVA) – Instructions and clarity were added for pilots to remain within the visual climb over airport (VCOA) specified visibility when departing an airport instrument flight rules (IFR) using VCOA.
5−4−20. APPROACH AND LANDING MINIMUMS – Removes outdated and incorrect verbiage and re−aligns AIM/AIP verbiage with FAA Order 8260.58.
7−1−8. INFLIGHT WEATHER ADVISORY BROADCASTS – This change removes Severe Weather Forecast Alerts (AWW) from paragraph 7−1−8, Inflight Weather Advisory Broadcasts, which are not broadcast by Terminal or ARTCC controllers.
9−1−4. GENERAL DESCRIPTION OF EACH CHART SERIES – This change updates frequency of chart production. In cases where annually or biannual updates were made, 56 day chart updates replace those longer update periods, and reduce the NOTAM burden and bring NAS changes to aviators in a timely manner.
