I'm looking for a complete list of the types of NOTAMs that can be found in the USA and under the ICAO definition. I looked at this question and it gives me a good starting point, but I'm not clear on how NOTAMs vary between the USA and when ICAO is used. Or maybe the USA is using "the ICAO way."
Is there a document that could help me compare where there is overlap and where there is a difference between how NOTAMs are defined in the USA and internationally. I assume there are ICAO definitions for NOTAMs that are used internationally.
If there are specific definitions for NOTAMs for countries other than the USA, that would fall outside the scope of my question here but might be an interesting additional subject matter for a very thorough answer.
There are significant differences between US domestic NOTAMs and international NOTAMs, please note that US NOTAM Office issues NOTAMs in both formats (NOTAMs susceptible to affect international flights being issued in international format). Canada is also issuing domestic NOTAMs in the same format than US.
Domestic NOTAMs are mainly split between D NOTAMs (about airports and navigation facilities) and FDC NOTAMs (about airspace, procedures or regulations), there are also military NOTAMs with more subtypes.
there is to my knowledge no document describing in detail all differences between both encodings, although the FAA order 7930.2R is quite detailed and provide information on both types and some list of differences.
There are many differences between both formats, for example:
domestic NOTAMs are easily recognized as they start with an exclamation point !
the international NOTAM encoding is more structured. For example, a Q field will summarize essential NOTAM information, including affected FIR, vertical boundaries, geographic coordinates. In US NOTAM, geographic coordinates is described in the text of the NOTAM and then less easily decoded automatically.
the Q code also store the type of affected facility and the state of the facility. US encoding for facility types is different.
domestic NOTAMs are using standardized phrases defined in FAA document but not recognized by ICAO standard, the FAA order 7930.2R list them.
