Regional Differences

International Operations Manual

Eddie sez:

Going to a country you've never been?

Bring along someone who has. Failing that, talk to another pilot who has been. Failing that, have a good handler with inside information about the ins and outs of the airports you are visiting.

With or without this kind of help, you should still do some homework:

  • The Aeronautical Information Publications (AIPs) — are your primary sources for information about the rules and regulations for countries you fly to or over. You can think of an AIP as that nation's AIM. In fact, you can see a lot of our AIP in our AIM. Of course not all AIPs are available in English and those that are can be a long, tedious read.
  • ICAO Doc 7030 is the "official" source of the differences each region of the world has from the ICAO standard. There are two problems, however. First, ICAO Doc 7030 isn't updated as often as it should be. Second, it covers regions and individual countries in the region could have differences above and beyond what is listed in 7030.
  • The Jeppesen State Pages should give you everything you need to know about a particular country's difference, though it is a broad brush view and is probably not as complete as the AIP.
  • The Jeppesen Airport Pages are also a must read, even if you have gone through the AIP.
  • There are also many good Internet sources.

If you haven't been to a region in a few years, it really pays to talk to someone who has. If you don't speak the language it pyas double to have a contact at the airport to make things run smoothly for you, a good trip handler can be invaluable.

Keep in mind things are constantly changing, but I've included notes about navigation performance, RVSM, altimeter procedures, and ICAO differences for the various regions in a list below.

While things are definitely becoming more standardized, there are still very big differences between many countries on how airplanes are expected to fly. The International Civil Aviation Organization (ICAO) sets out a game plan for all to follow, then allows everyone to change whatever they please, provided they publish the differences in their own Aeronautical Information Publication (AIP). How is your Nepalese? You would have to be able to read it to find out the flight levels in Nepal are based on quadranteal altitudes below 13,500 feet. What's an international pilot to do?

Everything here is from the references shown below, with a few comments in an alternate color.

Aeronautical Information Publications (AIPs)

What is an AIP?

An AIP is a requirement levied upon a country as price of membership to the ICAO; they have to publish one.

[ICAO Annex 15, Chapter 4]

Note 1.— AIP are intended primarily to satisfy international requirements for the exchange of aeronautical information of a lasting character essential to air navigation. When practicable, the form of presentation is designed to facilitate their use in flight.

Note 2.— AIP constitute the basic information source for permanent information and long duration temporary changes.

What is in an AIP?

Knowing what is supposed to be inside an AIP can help you find what hyou need to know before using a country's airspace or airports.

[ICAO Annex 15, ¶4.2]

  1. Each AIP shall be self-contained and shall include a table of contents.
  2. Note.— If it is necessary by reason of bulk or for convenience, to publish an AIP in two or more parts or volumes, each of them will indicate that the remainder of the information is to be found in the other part(s) or volume(s).

    • Each AIP shall not duplicate information within itself or from other sources.
    • When two or more States combine to issue a joint AIP, this shall be made clear both on the cover and in the table of contents.
  3. Recommendation.— AIP should be published in loose-leaf form unless the complete publication is reissued at frequent intervals.
  4. Each AIP shall be dated. In the case of AIP issued in loose-leaf form, each page shall be dated. The date, consisting of the day, month (by name) and year, shall be the publication date or the effective date of the information.
  5. A checklist giving the current date of each page in the AIP series shall be reissued frequently to assist the user in maintaining a current publication. The page number/chart title and date of the checklist shall appear on the checklist itself.
  6. Each AIP issued as a bound volume and each page of an AIP issued in loose-leaf form shall be so annotated as to indicate clearly:
    1. the identity of the AIP;
    2. the territory covered and subdivisions when necessary;
    3. the identification of the issuing State and producing organization (authority);
    4. page numbers/chart titles;
    5. the degree of reliability if the information is doubtful.
  7. Recommendation.— The sheet size should be no larger than 210 × 297 mm, except that larger sheets may be used provided they are folded to the same size.
  8. All changes to the AIP, or new information on a republished page, shall be identified by a distinctive symbol or annotation.
  9. Operationally significant changes to the AIP shall be published in accordance with Aeronautical Information Regulation and Control (AIRAC) procedures and shall be clearly identified by the acronym — AIRAC.
  10. AIP shall be amended or reissued at such regular intervals as may be necessary to keep them up to date. Recourse to hand amendments or annotations shall be kept to the minimum. The normal method of amendment shall be by means of replacement sheets.

How is an AIP Organized?

Most AIPs are organized into three parts that will help you target your search.

[United States Aeronautical Information Publication, ¶3.1] The AIP is made up of three Parts; General (GEN), En Route (ENR), and Aerodromes (AD); each divided into sections and subsections as applicable, containing various types of information subjects.

Where do I find a country's AIP?

Ah, that is the important question, isn't it? You can just type the country's name followed by "Aeronautical Information Publication" and hope for the best. The best source I've found, as of early 2017, is: http://gis.icao.int/gallery/ONLINE_AIPs.html

One of the problems with having an exhaustive list of anything that has anything to do with international operations is that they quickly become out of date. The link for the U.S. AIP on that list, for example, is out of date. The correct link is: https://www.faa.gov/air_traffic/publications/media/aip.pdf

ICAO Doc 7030

ICAO Doc 7030 Regional Supplementary Procedures and ICAO Doc 7030 Amendment 1 , are the official publication of regional differences between individual countries and the ICAO standard. In theory this should be your "go to" source, but it is woefully out of date. Nonetheless, there is good information to be had here.

State Pages

The Jeppesen Airways Manuals should give you everything you need before visiting or overflying another country and have the added advantage of being written in a language you can understand. Even with an AIP at my side, I always give the State Pages a look for those countries I am visiting or overflying. I'll also look at the airport pages for those I am visiting.

The "State Pages" in the Jeppesen airway manual refers to the following tabs:

  • Air Traffic Control Data — RVSM, volcanic ash, special navigation and communications procedures, to name a few.
  • State Rules and Procedures — Units of measurement, WGS-84, flight procedures, airport minimums, ICAO differences, for example.
  • Entry Requirements — Passport and Visa rules, health requirements, airspace entry, airports of entry, etc.
  • Emergency Procedures — Special procedures, radio communications failure, search and rescue, as well as ICAO differences.
  • Airport Directory — Airport hours, fire fighting rescue coverage, pavement classification, etc.

While they aren't always perfectly up-to-date, they often present your only source of need to know information.

Airport Pages

The Jeppesen airport pages are a must read, for starters. While for many airports there is little to learn there, for others the information is critical and you won't find it any place else. At Paris Le Bourget, for example, this is the only place you have access to, unless you have a French AIP, where you will find out the normal landing runway, the reverse thrust rules after 2215L, and a unique rule that allows you to intercept an ILS localizer without ATC instructions under some circumstances. Since these pages are updated frequently, every time you go to a particular airport you need to look at every page!
