Explanation of Changes

E of Chg−2

i. 4−5−7. Automatic Dependent Surveillance−

Broadcast (ADS−B) Services
This change emphasizes that an aircraft’s ADS−B

Flight Identification (FLT ID) must match the aircraft

identification annotated in the filed flight plan to

receive air traffic services. It also adds the term and

acronym, Call Sign Mis−Match (CSMM), for

consistency with FAA Order JO 7110.65.

j. 5−1−8. Flight Plan (FAA Form 7233−1) −

Domestic IFR Flights
This change updates pilot guidance to incorporate air

traffic control (ATC) procedures for GNSS−equipped

aircraft operating on area navigation (RNAV) air

traffic service (ATS) routes and on random

point−to−point and random impromptu routes in

airspace in which ATC procedures are applied,

excluding oceanic airspace. This change also

incorporates the use of the term GNSS in place of

RNAV for space−based positioning and navigation


k. 5−1−8. Flight Plan (FAA Form 7233−1) −

Domestic IFR Flights
This change adds guidance that allows the navigation

provided by GPS as an acceptable alternative to Great

Circle Routes. This change is for aircraft equipped

with latitude/longitude coordinate navigation capa-

bility flying random routes at and above FL 390

within the conterminous United States. 

l. 5−1−8. Flight Plan (FAA Form 7233−1) −

Appendix 3. Abbreviations/Acronyms

This change deletes obsolete references to Interna-

tional Flight Information Manual (IFIM) in para-

graphs 5−1−8 and 5−1−9 as well as Appendix 3. This

change retitles paragraph 5−1−11. The change to

subparagraph 5−1−11d removes the obsolete refer-

ence to IFIM and replaces it with a reference to the

appropriate AIP (of the foreign location). The change

to subparagraph 5−1−11e removes obsolete refer-

ences to foreign NOTAM information and adds a

reference to the FAA’s Prohibitions, Restrictions, and

Notices website. The change to subparagraph

5−1−11f clarifies customs notification to foreign

locations and also removes all outdated and obsolete

customs information. This change also adds

subparagraph 5−1−11h which provides a pointer

reference for entry requirements into U.S. territorial


m. 5−3−4. Airways and Route Systems

This change deletes the NOTE regarding Advisory

Circular 90−100A which is no longer useful.

n. 5−4−5. Instrument Approach Procedure

This change more succinctly describes when a

vertical descent angle (VDA) is published. It also

addresses VDA charting differences that may occur

between the FAA and commercial chart and database


o. 7−1−2. FAA Weather Services

7−1−5. Preflight Briefing

7−1−8. Telephone Information Briefing
