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. 1-1-18. Global Positioning System (GPS)

This change explains how pilots should use a Computer Navigation Fix (CNF) in Area Navigation (RNAV) system operations.

c. 1-1-18. Global Positioning System (GPS)
5-2-8. Instrument Departure Procedures (DP) - Obstacle Departure Procedures 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 updates guidance on the impact of magnetic variation on RNAV systems.

d. 3-5-2. Military Training Routes

This change updates route charting guidance and publishing information.

e. 4-4-12. Speed Adjustments
5-5-9. Speed Adjustments

This change clarifies existing speed termination procedures, adds the phraseology “resume published speed,” and redefines the phraseology “resume normal speed.”

f. 5-1-8. Flight Plan (FAA Form 7233-1) - Domestic IFR Flights
5-3-4. Airways and Route Systems

This change implements revised air traffic control (ATC) surveillance requirements for Global Navigation Satellite System (GNSS)-equipped aircraft operating on RNAV ATS routes, random and on random (impromptu) single point-to-point RNAV routes in controlled airspace, excluding oceanic airspace.

g. 5-2-8. Instrument Departure Procedures (DP) - Obstacle Departure Procedures 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 incorporates updated guidance on resumption of published altitude and speed restrictions, guidance on what is expected of aircrews when issued a “climb via" clearance, and clarifies the expectation that pilots will advise the receiving controller of the altitude being vacated and the altitude they are climbing to when changing frequencies.

h. 5-3-2. Position Reporting

This change clarifies guidance on reporting requirements in the Oceanic environment.

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

This change updates guidance to reflect the fact that the initial approach fix (IAF) waypoint is not an IAF, but an intermediate fix (IF). This change also updates guidance on descent below the minimum descent altitude (MDA).

j. 5-4-13. ILS/MLS Approaches to Parallel Runways

This change was made to clarify the distance requirements and make the definition apply to all applicable approach types, not just “ILS.”

k. 5-4-14. Parallel ILS/MLS Approaches (Dependent)

This change adds references to include RNAV and GNSS Landing System (GLS) approaches.

l. 5-4-15. Simultaneous Parallel ILS/MLS Approaches (Independent)

This change adds references to include RNAV and GLS approaches. The upper limit of 9,000 feet runway spacing for simultaneous parallel ILS/RNAV/GLS approaches was also added.

m. 5-4-16. Simultaneous Close Parallel ILS PRM and RNAV (GPS) PRM Approaches (Independent) and Simultaneous Offset Instrument Approaches (SOIA)

This change expands the use of ILS PRM and localizer type directional aid (LDA) PRM approaches to also mean RNAV PRM and GLS PRM approaches. Explanation of FMC coding of the SOIA offset approach is also added. Further, this change updates guidance regarding runway separation when high update PRM radar is required to conduct simultaneous close parallel approaches.

n. 5-4-15. Simultaneous Parallel ILS/MLS Approaches (Independent)
5-4-16. Simultaneous Close Parallel ILS PRM and RNAV (GPS) PRM Approaches (Independent) and Simultaneous Offset Instrument Approaches (SOIA)
5-4-17. Simultaneous Converging Instrument Approaches

Microwave Landing System (MLS) is no longer an approach option and was deleted.

o. 5-6-1. National Security

This change adds the Title 14 of the Code of Federal Regulations Section 99.7 (14 CFR 99.7) description of “Special Security Instructions” and the 14 CFR 99.3 definition of “Defense Area.” In addition, the Emergency Security Control of Air Traffic (ESCAT) overview has been retitled and moved under a new subparagraph.

p. 7-1-3. Use of Aviation Weather Products
7-1-11. Flight Information Services (FIS)

This change updates information and guidance to modify outdated information, reflect policy and terminology changes, and address changing technologies.

q. 7-1-1. National Weather Service Aviation Products
7-1-6. Inflight Aviation Weather Advisories
7-1-14. ATC Inflight Weather Avoidance Assistance
7-1-31. International Civil Aviation Organization (ICAO) Weather Formats

This change updates information and guidance at the request of the National Weather Service (NWS) as the information was outdated.

r. 7-1-14. ATC Inflight Weather Avoidance Assistance

This change was added to expand the meaning of the phrase “when able" when used in conjunction with a clearance to deviate around weather. The clearance to deviate is clarified to allow maneuvering within the lateral limits of the deviation clearance.

s. 7-1-29. Thunderstorm Flying

This change updates information and guidance to reflect new information in Advisory Circular 00­24C, Thunderstorms, published on February 19, 2013.

t. Entire publication.

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