than that prescribed by the applicable published instrument approach procedure. The IFR landing
minimums prescribed in paragraphs C0009 for Non-Precision approaches and C0047 for Precision
approaches of these operations specifications are the lowest Category I minimums authorized for use
at any airport.
a. Contact Approaches. The certificate holder shall not conduct contact approaches, unless the
pilot-in-command has satisfactorily completed an approved training program for contact
approaches. In addition, the certificate holder shall not conduct a contact approach unless the
approach is conducted to an airport with an approved instrument approach procedure for that
airport, and all of the following conditions are met:
(1) The flight remains under instrument flight rules and is authorized by ATC to conduct a contact
approach.
(2) The reported visibility/RVR for the runway of intended landing is at or above the authorized
IFR minimum for the Category I Precision and Non-Precision approach established for that
runway or 1600m (RVR 1500m), whichever is higher.
(3) The flight is operating clear of clouds and can remain clear of clouds throughout the contact
approach. The flight visibility must be sufficient for the pilot to see and avoid all obstacles and
safely maneuver the aircraft to the landing runway using external visual references.
(4) The flight does not descend below the MEA/MSA, MVA, or the FAF altitude, as appropriate,
until:
(a) The flight is established on the instrument approach procedure, operating below the
reported ceiling, and the pilot has identified sufficient prominent landmarks to safely
navigate the aircraft to the airport, or
(b) The flight is operating below any cloud base which constitutes a ceiling, the airport is in
sight, and the pilot can maintain visual contact with the airport throughout the
maneuver.
(5) The flight does not descend below the highest circling MDA prescribed for the runway of
intended landing until the aircraft is in a position from which a descent to touch down, within
the touchdown zone, can be made at a normal rate of descent using normal maneuvers.
b. If Applicable, Special Limitations and Provisions for Instrument Approach Procedures at Foreign
Airports.
(1) Foreign approach lighting systems equivalent to Chinese standards are authorized for
Precision and Non-Precision instrument approaches. Sequenced flashing lights are not
required when determining the equivalence of a foreign approach lighting system to Chinese
standards.

(2) For straight-in landing minimums at foreign airports where an MDA(H) or DA(H) is not
specified, the lowest authorized MDA(H) or DA(H) shall be obtained as follows:
(a) When an obstruction clearance limit (OCL) is specified, the authorized MDA(H) or
DA(H) is the sum of the OCL and the touchdown zone elevation (TDZE). If the TDZE
for a particular runway is not available, threshold elevation shall be used. If threshold
elevation is not available, airport elevation shall be used. For approaches other than
ILS, MLS, or GLS, the MDA(H) may be rounded to the next higher 5-meters (10-foot)
increment.
(b) When an obstacle clearance altitude (OCA)/obstacle clearance height (OCH) is
specified, the authorized MDA(H) or DA(H) is equal to the OCA/OCH. For approaches
other than ILS, MLS, or GLS, the authorized MDA(H) may be expressed in intervals of
5meters (10 feet).
(c) The HAT or HAA used for precision approaches shall not be below those specified in
subparagraph a of this operations specification.
(3) When only an OCL or an OCA/OCH is specified, visibility and/or RVR minimums appropriate
to the authorized HAA/HAT values determined in accordance with subparagraph b(2) above
will be established in accordance with criteria prescribed by CCAR97, U.S. TERPS or Joint
Aviation Requirements, operational agreements, Part 1 (JAR-OPS-1).
(4) When conducting an instrument approach procedure outside China, the certificate holder shall
not operate an aircraft below the prescribed MDA(H) or continue an approach below the
DA(H), unless the aircraft is in a position from which a normal approach to the runway of
intended landing can be made and at least one of the following visual references is clearly
visible to the pilot:
(g) Runway, runway markings, or runway lights.
(h) Approach light system
(i) Threshold, threshold markings, or threshold lights.
(j) Touchdown zone, touchdown zone markings, or touchdown zone lights.
(k) Visual glidepath indicator (such as VASI or PAPI).
