Aeronautical Information Manual
Explanation of Changes

Effective: November

a. 2-1-2. Visual Glideslope Indicators

Based on a request made at the Aeronautical Charting
Forum, the safe obstruction clearance provided by the
visual glide path of the precision approach path
indicator is now 3.4 NM from the runway threshold,
rather than 4 SM.

b. 4-1-13. Automatic Terminal Information

Service (ATIS)

This change updates the content and structure of
subparagraph b to reflect the current METAR format
and to be in congruence with material in FAA Order
JO 7110.65, Air Traffic Control, Paragraph 2-1-3,

c. 4-3-11. Pilot Responsibilities When
Conducting Land and Hold Short Operations
FIG 4-3-7 has been updated to accurately reflect the
runway orientation.

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

This change indicates that controllers are now
allowed to use 5 knot increments when making speed

e. 4-6-1. Applicability and RVSM Mandate
(Date/Time and Area)
4-6-3. Aircraft and Operator Approval
Policy/Procedures, RVSM Monitoring and Data-
bases for Aircraft and Operator Approval

4-6-5. Pilot RVSM Operating Practices and
4-6-7. Guidance on Wake Turbulence
4-6-10. Procedures for Accommodation of
Non-RVSM Aircraft
This change reflects updated Reduced Vertical
Separation Minimum (RVSM) policy and procedures
and supports changes to Advisory Circular 91-85A,
Authorization of Aircraft and Operators for Flight in
Reduced Vertical Separation Minimum Airspace.

10, 2016

This change also updates the FAA's RVSM website

f. 5-1-9. International Flight Plan (FAA Form
7233-4)-IFR Flights (For Domestic or
International Flights)
The International Civil Aviation Organization
(ICAO) has replaced the designation of Minimum

Navigation Performance Specification (MNPS) with

the designation North Atlantic (NAT) High Level
Airspace (HLA), assigned to qualifier code "X."
Airframes that currently have MNPS authorization
will be allowed to operate in the NAT HLA under that
authorization until 2020. All who wish to operate in
the NAT HLA, who are not grandfathered in under
MNPS, will need an RNP 4 or RNP 10 approval. TBL
5-1-4, Aircraft COM, NAV, and Approach
Equipment Qualifiers, is updated to provide the new
definition for the qualifier code "X."
g. 5-2-8. Instrument Departure Procedures
(DP)-Obstacle Departure Procedures (ODP)
and Standard Instrument Departures (SID)

This change clarifies that air traffic control (ATC)
cannot modify crossing altitudes and/or speed
restrictions on ODPs, as they are needed to ensure
obstacle avoidance.

h. 5-4-5. Instrument Approach Procedure
This change provides guidance to pilots regarding
what to expect from ATC when receiving assigned
altitudes below the terminal arrival area (TAA).

i. 5-4-6. Approach Clearance

This change adds "Cancel Approach Clearance" to
inform the pilot that a previously issued approach
clearance is canceled. ATC will also include
additional instructions if necessary.
j. 5-4-14. Parallel ILS Approaches
This change introduces the use of 1.5 NM radar
separation diagonally on simultaneous dependent
approaches when runway centerlines are separated by
