A Complete Manual for Conducting International Flight Operations
FAA vs. ICAO Procedures & Phraseology
FAA vs. ICAO PROCEDURES
There are many differences between FAA and ICAO procedures. Complicating the matter even more, many countries will use some ICAO procedures, some will use FAA procedures, and additionally, some may create their own procedures. For this reason it is very important for crewmembers to have a basic knowledge of FAA VS. ICAO differences and to spend the time researching country specific differences from ICAO.
The following are general guidelines and are not intended to be all inclusive.
Limited to 250 Knots below 10,000’
Generally no equivalent
The METAR abbreviation SKC is used to indicate clear sky
CAVOK is used which implies a visibility of 10 km and no cloud condition below 5000 ft or the highest minimum sector altitude and no cumulonimbus or towering cumulus at any level.
The FAA does not prohibit aircraft from departing for their destination when the weather is below approach minimums under part 91, however FAR 135.319 does have restrictions that apply when flying commercially.
Destination Weather at the Time of Departure
ICAO has restrictions which are called “Approach Ban”. They prevent aircraft from departing when the destination weather is below minimums. When operating in a foreign country, those country specific rules apply to U.S. operators.
If the failure occurs in IFR conditions each pilot shall continue the flight according to the following:
The highest of the following:
Lost Com in IFR Flight
In ICAO the aircraft shall, while under radar contact, maintain the last assigned speed and level for 7 minutes after the latter of the following:
While outside of radar contact the aircraft shall maintain the last assigned speed and level, or minimum flight altitude if higher for 20 minutes following the aircraft’s failure to report its position over acompulsory reporting point and thereafter adjust level and speed in accordance with the filed flight plan (ICAO Annex 2 18.104.22.168.2)
FAA vs. ICAO PHRASEOLOGY
ICAO and FAA phraseology is very similar, but knowing the subtle differences can have a significant impact on flight operations. Crew members shall review the brief list prior to conducting international flight operations.
