Draft AC Reflects Changes to IFR Approaches
New AC also incorporates information pertaining to international all-weather operations (AWO) criteria harmonization between the FAA and EASA.

A new draft Advisory Circular (AC 120-xLS) provides an FAA-approved means of obtaining and maintaining authorization of operations in ground-based Category I, Category II, and Category III landing weather minimums and IFR lower than standard takeoff minimums. This AC reflects “significant revision of information” that occurred in 2011when the FAA removed the definitions of Category IIIa, IIIb, and IIIc operations, and discontinued the use of this nomenclature in subsequent documentation.
