this paragraph are the lowest Category I minimums authorized for use at any airport.
a. ILS, MLS, or GPS Landing System (GLS) Category I Approach Procedures. The certificate
holder shall not use an IFR landing minimum for precision, ILS, MLS, or GLS approach
procedures lower than specified in the following table. Touchdown zone RVR reports, when
available for a particular runway, are controlling for all approaches to and landings on that
runway.

NOTE 2: The mid RVR and rollout RVR reports (if available) provide advisory information to pilots.
The mid RVR report may be substituted for the TDZ RVR report if the TDZ RVR report is not
available.
NOTE 3: These minimums apply to autoland or HGS-equipped aircraft when operated by a properly
qualified flightcrew and flown in the appropriate CAT III annunciation mode at the authorized
airports and runways listed in paragraph b. below.
b. The certificate holder is authorized precision Category I landing minimums as low as RVR 550m
(1800ft) without touchdown zone and centerline lights with autoland or HGS-equipped aircraft at
the following airports and runways:

c. Special Aircrew, Aircraft Authorized Minimums. The certificate holder shall not use an IFR
landing minimum for straight-in precision Category I approaches labeled as “Special Aircrew,
Aircraft Authorization Required” except in accordance with subparagraph a of this operations
specification and the following:
(1) The authorized aircraft must be equipped with an approved approach coupler, flight director,
or a head-up guidance system (HGS) which provides guidance to decision height. Pilots-incommand
(PIC) must be required to engage the autopilot coupler, flight director, or HGS as
applicable and use it to decision height or initiation of missed approach unless adequate
visual references with the runway environment are established which allow safe continuation
to a landing.
(2) Should the autopilot, flight director, or HGS malfunction or be disengaged during the
approach, the PIC must execute a missed approach not later than arrival at standard
minimums unless visual reference to the runway environment has been established.
(3) Pilots must be trained in the use of the autopilot coupler, flight director, or HGS as applicable
and demonstrate proficiency in ILS approaches to minimums using this equipment on checks
conducted to satisfy CCAR 121.465 or 135.297.
d. Limitations and Provisions for Instrument Approach Procedures at Foreign Airports. If the
certificate holder operates to foreign airports the following applies:
(1) Foreign approach lighting systems equivalent to Chinese standards are authorized for
precision and nonprecision 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
