Aeronautical Information Manual
Explanation of Changes

Effective: December

a. 1-1-17. Global Positioning System (GPS)
5-1-16. RNAV and RNP Operations

This change reflects the migration from
raimprediction.net to the Service Availability
Prediction Tool (SAPT).

b. 2-3-14. Aircraft Arresting Systems

This change adds information to describe how the
Engineered Materials Arresting System (EMAS) is
marked. It also clarifies guidance regarding taxiing
across the runway.

c. 3-2-4. Class C Airspace
4-2-4. Aircraft Call Signs
4-3-10. Intersection Takeoffs
4-4-14. Visual Separation
5-5-11. Visual Approach
7-3-8. Pilot Responsibility
7-3-9. Air Traffic Wake Turbulence

This change adds a new weight class designated as
"Super" and updates the associated guidance as
appropriate. It also includes changes to wake
turbulence separation behind B757 aircraft.

d. 4-1-20. Transponder Operation

This change updates transponder and Automatic
Dependent Surveillance-Broadcast (ADS-B) opera-
tional procedures while on the airport surface and

e. 4-3-19. Taxi During Low Visibility

This change updates the runway visual range (RVR)
from 600 RVR to 500 RVR. It also changes Surface
Movement Guidance and Control System (SMGCS)
to Low Visibility Operations Surface Movement
Guidance and Control System (LVOSMGCS).
10, 2015

f. 4-5-7. Automatic Dependent Surveillance-
Broadcast (ADS-B) Services
4-5-8. Traffic Information Service-Broad-
cast (TIS-B)
4-5-9. Flight Information Service-Broadcast
4-5-10. Automatic Dependent Surveillance-
Rebroadcast (ADS-R)

Safe Flight 21 is now part of the national Surveillance
and Broadcast Services-Automatic Dependent
Surveillance-Broadcast (SBS/ADS-B) Program.
Therefore, this change removes references to the Safe
Flight 21 program and updates its contact
information, including telephone numbers and
website URL information. The guidance that pilots
report all malfunctions to flight service stations
remains unchanged.

g. 5-1-17. Cold Temperature Operations
5-5-4. Instrument Approach
5-5-5. Missed Approach

In response to aviation industry concerns over cold
weather effects on indicated altitudes versus that of an
aircraft's true altitude, the FAA completed a safety
study to determine if current 14 CFR Part 97
instrument approach procedures in the United States
National Airspace System are at risk of compromised
required obstacle clearances during time of extreme
cold temperature. A safety risk management panel
(SRMP) was conducted on the impact to ATC
operations, and a condition of the SRMP was to add
content to the Aeronautical Information Manual to
assist in a pilot's awareness of the need to apply cold
temperature correction. This change adds guidance
under preflight planning to account for Cold
Temperature Correction. It also adds the provision
under pilot responsibilities that, during instrument
approaches, the pilot must advise ATC when there is
a need to apply cold temperature correction and, if so,
how much is being applied.
