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 (De-

pendent)
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.
