Aeronautical Information Manual

Explanation of Changes

Effective: August 22, 2013

a. 1-1-16. VHF Direction Finder
       6-2-3. Direction Finding Instrument Approach Procedure
      Appendix 4. Abbreviation/Acronyms

The FAA has decommissioned all Direction Finders (DF) in the national airspace system. As such, all references to DFs have been removed from approaches, procedures, supplements, charts, and publications.

b. 1-1-19. Global Positioning System (GPS)
       1-1-20. Wide Area Augmentation System (WAAS)
       1-2-3. Use of Suitable Area Navigation (RNAV) Systems on Conventional Procedures and Routes
       5-4-5. Instrument Approach Procedure Charts

This change explains the types of Global Navigation Satellite System procedures that may be used for alternate planning. This change also added circling where appropriate.

c. 4-1-13. Automatic Terminal Information Service (ATIS)

The Spectrum Engineering Office is amending ambiguous content associated with the ATIS to clarify requirements and coverage between arrival and departure messages.

d. 4-2-4. Aircraft Call Signs
      4-6-1. Applicability and RVSM Mandate (Date/Time and Area)
      4-6-5. Pilot RVSM Operating Practices and Procedures
      4-6-10. Procedures for Accommodation of Non-RVSM Aircraft
      5-1-9. International Flight Plan (FAA Form 7233-4) - IFR Flights

The term “Lifeguard" is being replaced by the term “MEDEVAC." The previous “MEDEVAC" meaning has been removed. The term “HOSP" has been added.

e. 4-3-20. Exiting the Runway After Landing

This change was made to harmonize the language in said paragraph with the regulatory language in Title 14, Code of Federal Regulation (CFR) 91.129 and AIM paragraph 4-3-18. It emphasizes the fact that the clearance does not authorize the aircraft to “enter" or “cross" any runways.

f. 5-1-3. Notice to Airmen (NOTAM) System

This change amends the AIM to agree with changes made during the rewrite of FAA Order JO 7930.2, Notices to Airmen.

g. 5-1-6. Flight Plan - Defense VFR (DVFR) Flights

In accordance with the Title 14 CFR 99.3 definition for DVFR, DVFR procedures do not apply to Department of Defense (DOD) and law enforcement flights. This change clarifies that DOD and law enforcement aircraft are not required to file DVFR flight plans.

h. 4-4-12. Speed Adjustments
   5-2-8. Instrument Departure Procedures (DP) - Obstacle Departure Procedures (ODP) and Standard Instrument Departures (SID)
     5-4-1. Standard Terminal Arrival (STAR), Area Navigation (RNAV) STAR, and Flight Management System Procedures (FMSP) for Arrivals

This change implements FAA InFO 07011, dated May 17, 2007. It emphasizes that separation and sequencing of airplanes by air traffic control depends on uniform performance by pilots with respect to published altitude and speed constraints, especially when conducting RNAV procedures.

i. 5-2-8. Instrument Departure Procedures (DP) - Obstacle Departure Procedures (ODP) and Standard Instrument Departures (SID)

This change updates references to the U.S. Terminal Procedures booklets.

j. 5-3-2. Position Reporting

This change updates the AIM to reflect existing policy contained in FAA Order 7110.65, Air Traffic Control, and the Advanced Technologies and Oceanic Procedures Operating Manual. Ocean21 requires a position report for any fix that is filed in the flight plan even if it is considered to be non-compulsory. This change requires pilots to report over all non-compulsory reporting points as well as compulsory reporting points.

k. 5-4-6. Approach Clearance
      5-4-7. Instrument Approach Procedures

This change provides guidance when the glideslope is unusable; all references to the MLS approach have been removed, and LDA, SDF, and GLS approaches are added as examples. It provides guidance for informing the pilot when the controller requires the aircraft to fly a straight-in approach and not fly the hold-in-lieu-of procedure turn. This change adds a provision that permits vectoring to any fix along the final approach course prior to the final approach fix (FAF). It allows appropriately-equipped RNAV aircraft to be cleared to the intermediate fix (IF) on conventional and RNAV instrument approach procedures when the IF is identified with “IF" on the instrument approach procedures. This change creates new procedures and graphics for aircraft on unpublished routes cleared direct to a fix between the IF and FAF and for handling radius to fix (RF) legs contained on RNAV approaches. This change clarifies air traffic control procedures to be applied in conjunction with aircraft executing RNAV approaches containing RF legs.

l. 5-4-16. Simultaneous Close Parallel ILS PRM Approaches (Independent) and Simultaneous Offset Instrument Approaches (SOIA) (See FIG 5-4-21)

This changes reflects a major update to guidance for Precision Runway Monitor and SOIA approaches and introduces RNAV (GPS).

m. 5-4-20. Approach and Landing Minimums

This change was made to make pilots aware of the fact that circling approach protected areas developed after late 2012 use the radius distance shown in the table on page B2 of the U.S. Terminal Procedures Publication. They are dependent not only on aircraft approach category, but also on the altitude of the circling minimum descent altitude (MDA), which accounts for true airspeed increase with altitude. The approaches using expanded circling approach areas can be identified by the presence of the “negative C" symbol on the circling line of minima.

n. 7-1-27. PIREPs Relating to Volcanic Ash Activity
      7-5-9. Flight Operations in Volcanic Ash

This change provides expanded and updated information related to Volcanic Ash and the Volcanic Advisory Report as specified by the International Civil Aviation Organization.

o. 7-5-12. Light Amplification By Stimulated Emission of Radiation (LASER) Operations and Reporting Illumination of Aircraft
      Appendix 3. Laser Beam Exposure Questionnaire

This change updates the formal reporting process for pilots that experience an unauthorized laser illumination of aircraft incident. Pilots will now be referred to the FAA Laser Safety Initiative website at for access to the updated Laser Beam Exposure Questionnaire where they will have the option to submit the completed questionnaire electronically. The Laser Beam Exposure Questionnaire is being removed from the AIM.

p. Entire publication.

Editorial/format changes were made where necessary, to include recent organization name changes. Revision bars were not used when changes are insignificant in nature.
