Aeronautical Information Manual

Explanation of Changes

Effective:  April 3, 2014

a. 1-1-3. VHF Omni-Directional Range (VOR)

This change reflects the fact that some VOR receivers are capable of identifying the VOR.

b. 1-1-9. Instrument Landing System (ILS)

For those facilities that have had the middle marker decommissioned, this change identifies a distance (1/2 mile) from the approach end of the runway for protection of the Localizer Critical Area. This change also removes MLS from the required phraseology to advise pilots that the ILS Critical Area is not protected.

c. 1-1-11. Microwave Landing System (MLS)

This change removes the reference to the ILS service protection date of 2010.

d. 1-1-14. User Reports Requested on NAVAID or Global Navigation Satellite System (GNSS) Performance or Interference
4-5-6. Traffic Information Service (TIS)
4-5-7. Automatic Dependent Surveillance - Broadcast (ADS-B) Services
4-5-8. Traffic Information Service (TIS) - Broadcast (TIS-B)
7-1-11. Flight Information Services (FIS)

FAA Form 8740-5, Safety Improvement Report, is no longer used to report malfunctions. Therefore, references to this form have been deleted.

e. 1-1-21. Precision Approach Systems other than ILS, GLS, and MLS
2-1-5. In-runway Lighting
2-3-4. Taxiway Markings
2-3-5. Holding Position Markings
5-4-12. Radar Monitoring of Instrument Approaches

This change removes Microwave Landing System (MLS) as an approach type.

f. 4-1-22. Airport Reservation Operations and Special Traffic Management Programs

This change updates the contact information for the Airport Reservation Office since the Command Center's relocation to Vint Hill, VA.

g. 4-3-3. Traffic Patterns

This change adds a graphic that depicts headwind, crosswind, and tailwind calculation charts.

h. 4-6-9. Contingency Actions: Weather Encounters and Aircraft System Failures

This change is made to clarify to operators that they may request deviations per Title 14, of the Code of Federal Regulations (14 CFR), Part 91.180 (d) after entry into Reduced Vertical Separation Minimum (RVSM) airspace and not before.

i. 5-1-1. Preflight Preparation

This change reflects the cancellation of FAA Orders 7230.16C, Pilot Education Program-Operation Rain Check, and 7230.17, Pilot Education Program- Operation Takeoff.

j. 5-3-3. Additional Reports

This change harmonizes the AIM/Aeronautical Information Publication guidance with the most recent update to International Civil Aviation Organization (ICAO) Annex 2, Rules of the Air, Paragraph

k. 5-4-3. Approach Control
5-4-26. Landing Priority

This change removes references to MLS and adds references to include RNAV and GBAS Landing System (GLS) approaches.

l. 5-4-5. Instrument Approach Procedure Charts

This change clarifies the pilot's responsibility while descending on the glidepath in dependent and independent approaches. The content and graphics within the Terminal Arrival Area section is also updated to bring it in line with new procedures and terminology. In addition, this change provides an explanation (both visually and verbally) as to why circling minima may be lower than the LNAV/VNAV minima on the same approach plate.

m. 5-4-13. ILS/MLS Approaches to Parallel Runways
5-4-14. Parallel ILS/MLS Approaches (Dependent)

This change removes references to MLS and adds references to include RNAV and GLS approaches. It clarifies the runway spacing requirements for the use of final monitor controller and PRM radar. It also includes a discussion of pilot procedures when conducting simultaneous (parallel) dependent operations.

n. 5-4-15. Simultaneous Parallel ILS/RNAV/GLS Approaches (Independent)

This change clarifies the runway spacing requirement when No Transgression Zone (NTZ) monitoring is required. It also clarifies monitor controller procedures during NTZ monitoring of simultaneous (parallel) independent approaches.

o.  5-4-16. Simultaneous Close Parallel ILS/RNAV/GLS PRM Approaches (Independent) and Simultaneous Offset Instrument Approaches (SOIA)

This change adds RNAV PRM and GLS PRM approach discussions. It includes specific information about the unique Flight Management System coding issues for SOIA.

p. 5-4-17. Simultaneous Converging Instrument Approaches

This change broadens the requirements for conducting converging approaches to include approaches other than ILS.

q. 5-6-1. National Security

This change now contains complete instructions regarding Defense Visual Flight Rule position reporting prior to Air Defense Identification Zone penetration per 14 CFR 99.15.

r. 7-5-15. Avoid Flight in the Vicinity of Thermal Plumes (Smoke Stacks and Cooling Towers)

This change updates the terminology and provides more detail regarding the associated hazards of exhaust plumes.

s. 7-6-4. Unidentified Flying Object (UFO) Reports

This change removes outdated contact information regarding the collection and/or reporting of UFO phenomena.

t. Entire publication.

Editorial/format changes were made where necessary. Revision bars were not used when changes are insignificant in nature.
