Draft Advisory Circular (AC) No. 120-28D, Criteria for Approval
of Category III Weather Minima for Takeoff, Landing, and Rollout
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of availability of a draft advisory circular.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of a draft AC,
recommended by the Aviation Rulemaking Advisory Committee (ARCA), which
provides information and guidance on obtaining and maintaining approval
of Category III landing weather minima and low visibility takeoff
criteria, including the installation and approval of associated
aircraft systems. This draft AC would incorporate changes to AC 20-57
resulting from the harmonization efforts of the Federal Aviation
Administration, European Joint Aviation Authority and other regulatory
authorities. This notice solicits public comment on the draft AC.
DATES: Comments on the draft AC must be received on or before July 20,
1998.
ADDRESSES: Send all comments on the draft AC to Jim Enias, Technical
Programs Division (AFS-400), Room 835, Federal Aviation Administration,
800 Independence Ave., SW., Washington DC 20591.
FOR FURTHER INFORMATION CONTACT:
Jim Enias, Technical Programs Division (AFS-400), Federal Aviation
Administration, Independence Avenue, SW., Washington, DC 20591,
Telephone (202) 267-7211.
Comments Invited
The FAA invites interested parties to submit comments on this draft
AC, as recommended by the ARAC. Commenters should identify AC 120-28D
and submit comments to the person and address listed above. The FAA
will consider all communications received on or before the closing date
for comments before completing its review of this ARAC recommended AC.
The recommended draft AC and comments received may be inspected at the
Office of Flight Standards Service, Technical Programs Division, Room
935, Federal Aviation Administration (Federal Office Building 10A),
between the hours of 9 a.m. and 5 p.m. weekdays, except Federal
holidays.
Background
This draft AC was received from the ARAC on December 15, 1997. The
AC recommended by the ARAC would set forth an acceptable means, but not
the only means, of obtaining and maintaining approval of operations in
Category III landing weather minima and low visibility takeoff criteria
including the installation and approval of associated aircraft systems.
It includes additional or revised Category III criteria for use in
conjunction with heads-up displays, satellite navigation systems, low
visibility takeoff guidance systems, wide-body fail passive operations,
and use of Category III criteria during certain engine inoperative
operations.
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.
This draft revision also updates and incorporates provisions of the
former AC 20-57 into AC 120-28, since AC 20-57's former provisions are
directly related to and dependent on criteria provided in the draft AC.
The FAA is currently reviewing this ARAC recommendation and may
make revisions to this document before it is issued. These revisions
may include editorial changes to ensure that this AC does not impose
requirements on operators independent of the current regulations. The
regulations themselves, referenced in the draft AC, may be reviewed for
revisions, as appropriate. It should be noted that the draft AC
explicitly states that nothing in it is intended to preclude an
operator from proposing and demonstrating to the FAA its ability to
operate to Category III minima with a different equipment
configuration, or alternatively to an RVR minima lower than presently
described in this document.
If, after review of this recommendation, the FAA decides to make
any substantive changes in the draft AC, the revised document will be
made available again for comment before final issuance.
This draft revision incorporates changes resulting from the first
steps toward international all weather operations criteria
harmonization taken by the FAA, JAA, and several other regulatory
authorities. Subsequent revisions of this AC are planned as additional
all weather operations harmonization items are agreed and completed by
FAA and JAA, or internationally.
Issued in Washington, DC on May 15, 1998.
Thomas E. Stuckey,
Acting Director, Flight Standards Service.
