8/7/25 AIM
Aeronautical Information Manual
Explanation of Changes
Effective: August 7, 2025
a. 2−3−10. DIRECTION SIGNS
2−3−11. DESTINATION SIGNS
This change revises paragraph 2 −3−11, Destination Signs. This change coincides with an update of AC
150/5340−18 thus establishing an authorized source that supports FAA adding standardized chart labels for
parking areas to airport diagrams. The rewrite of paragraph 2−3−11 separates content for inbound destination
signs from content for outbound destination. This DCP also revises and recaptions FIG 2−3−38 to depict more
examples of inbound destination sign legends, and recaptions FIG 2−3−39 to reflect an outbound destination sign
example, and moves them to paragraph 2−3−11.
b. 4−3−3. AIRPORTS WITH AN OPERATING CONTROL TOWER
This change realigns the AIM definition and graphic depiction of upwind leg at towered airports with current
ATC use and expectation. ATC usage of upwind leg is an extension of departure. The AIM’s current definition
of upwind has led to confusion among pilots and controllers. The new proposed graphic depiction of upwind in
FIG 4−3−1 as well as the definition in 4−3−2c aligns with common usage at towered airports. Additionally, the
order of traffic pattern component definitions was reconfigured to align their definitions in a more logical
sequence beginning with departure.
c. 5–2–9. INSTRUMENT DEPARTURE PROCEDURES (DP) − OBSTACLE DEPARTURE
PROCEDURES (ODP), STANDARD INSTRUMENT DEPARTURES (SID), AND DIVERSE VECTOR
AREAS (DV A)
This change incorporates changes to instrument departure criteria for minimums and obstacle notes. Language
is added to identify the changes to departure charts and pilot/controller responsibilities.
d. 5–4–5. INSTRUMENT APPROACH PROCEDURE (IAP) CHARTS
This change updates information regarding instrument approach altimeter setting sources to include references
to airport identifiers.
e. 5–4–6. APPROACH CLEARANCE
5–4–7. INSTRUMENT APPROACH PROCEDURES
This change realigns cleared approach procedures, which was inadvertently added to paragraph 5 −4−7, to
paragraph 5−4−6. It also addresses arrival to approach connectivity procedures to assure pilots recognize and
implement the connection of arrivals (STARs) with an instrument approach procedure at the initial approach fix
where they exist.
f. 5–4–13. SIMULTANEOUS APPROACHES TO PARALLEL RUNWAYS
This change addresses curved and angled paths that may be used to intercept the final approach course and
emphasizes the importance of adhering to the approach procedure. Also, a correction is being made to the figure
that corresponds to the textual description.
g. 5−4−22. USE OF ENHANCED FLIGHT VISI ON SYSTEMS (EFVS) ON INSTRUMENT
APROACHES
This updates the EFVS section of the AIM to note this change, as well as, to call attention to the AFS 410 EFVS
website where each LED ALS is noted by runway end.

AIM 8/7/25
h. 7–1–1. NATIONAL WEATHER SERVICE A VIATION WEATHER SERVICE PROGRAM
7–1–3. USE OF A VIATION WEATHER PRODUCTS
7–1–9. FLIGHT INFORMATION SERVICES (FIS)
This change removes references to Advisory Circular 00 −45, Aviation Weather Services, and replaces with
FAA−H−8083−28, Aviation Weather Handbook. Making these changes will correct the AIM and bring it in
alignment with other FAA documents and publications.
i. 7–1–7. CATEGORICAL OUTLOOKS
This change amends the paragraph to include reported weather data as to how the categorical ceiling and visibility terms
are used.
j. 7–2–3. ALTIMETER ERRORS
This change assigns the waiver authority for 14 CFR § 91.144 to Air Traffic Organization (ATO) Service Center
Directors in their areas of jurisdiction, since AFS waiver procedures were incompatible with the short life of a
high barometric pressure NOTAM.
k. 7–6–18. AUTOMATIC LANDING OPERATIONS
This change adds guidance advising operators conducting automatic landing operations to first determine that
the flight control guidance system being used is compatible with the instrument approach procedure and runway
being used.
l. 9–1–3. SAFETY ALERTS, CHARTING NOTICES AND DATA PRODUCT NOTICES
This change adds descriptions of FAA published Safety Alerts (SA), Charting Notices (CN), and Data Product
Notices (DPN), and provides a hyperlink to the FAA website containing these notices.
m. Editorial Changes
Editorial changes include relocating some subparagraphs in paragraph 5–3–1 to match the corresponding
formatting in the Aeronautical Information Publication (AIP); correcting the title of paragraph 7–6–1 to
Accident Causal Factors; a universal change replacing all prior references to the term Gulf of America with
the term Gulf of America in accordance with Executive Order 14172; and a universal change updating the
term Notice to Air Missions (NOTAM) to Notice to Airmen (NOTAM).
n. Entire Publication
Additional editorial/format changes were made where necessary. Revision bars were not used because of the
insignificant nature of these changes.
