## Background

                        An initial draft of this AC was received from the Aviation Rulemaking Advisory committee (ARAC) in August 1998 and a notice of availability was published in the                         **Federal Register**                         in October 1998. The notice of availability stated that the FAA was reviewing the ARAC recommendation and that it may make revisions to the document before it is issued. The notice also stated that if the FAA decides to make any substantive changes in the draft AC, the revised document would be made available again for comment before final issuance. Subsequently, an internal FAA coordination process began in January 2000 and was completed in September 2000. This draft revision incorporates changes resulting from that review, as well as the ARAC recommendations and are the first steps toward international all weather operations criteria harmonization taken by the FAA, JAA and several other regulatory authorities. Comments received in response to this notice will be considered before a final AC is issued. This draft AC should be reviewed in conjunction with the regulatory requirements of 14 CFR parts 121, 125, and 135, as applicable. This draft AC would not change, add, or delete any regulatory requirement or authorize any deviation from parts 121, 125, or 135.                    

Issued in Washington, DC on October 6, 2000.

Director, Flight Standards.
