d. Part 121 Certificate Holders Only- When Pilot Flight Training and Flight Checking Are NOT
Provided. The Part 121 certificate holder is authorized to conduct a circle-to-land maneuver
without providing pilot training and checking. The following subparagraphs d(1) through d(3)
shall apply:
(1) The Part 121 certificate holder is authorized to conduct a circle-to-land maneuver without
providing pilot training and checking when:
(a) The reported ceiling is at least 300m (1,000ft) and the visibility is at least 4800m (3
statute miles); or
(b) The reported weather is at least equal to the charted circling landing minimums for the
approach to be used, whichever is higher.
(2) When pilot training and checking are not provided, the Part 121 certificate holder shall use a
Minimum Descent Altitude (MDA) of 300m (1000ft) (HAA) or the MDA of the charted circling
landing minimums for the approach to be used, whichever is higher.
(3) The Part 121 certificate holder is authorized to use the following aircraft to conduct circle-toland
maneuvers without providing pilot training and checking (if none are authorized, enter
N/A):

e. If Foreign Airports are Authorized. The following special limitations and provisions for instrument
approach procedures apply at foreign airports.
(1) Foreign approach lighting systems equivalent to Chinese standards are authorized for
precision, precision-like (other than ILS, MLS, or GLS), 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
5 meters (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:
(a) Runway, runway markings, or runway lights.
(b) Approach light system
(c) Threshold, threshold markings, or threshold lights.
(d) Touchdown zone, touchdown zone markings, or touchdown zone lights.
(e) Visual glidepath indicator (such as VASI or PAPI).
(f) Runway-end identifier lights.
