operation unless the following RVR reporting systems are installed and operational for the
runway of intended landing.
(1) For Category III landing minimums as low as RVR 600 (175 meters), the Touchdown Zone,
Mid, and Rollout RVR reporting systems are required and must be used. Touchdown Zone
and Mid RVR reports are controlling for all operations. The Rollout report provides advisory
information to pilots.

(2) For Category IIIb landing minimums below RVR 600 (175 meters) using fail-passive rollout
control systems, the Touchdown Zone, Mid, and Rollout RVR reporting systems are required
and must be used. All three RVR reports are controlling for all operations.
(3) For Category IIIb landing minimums below RVR 600 (175 meters) using fail-operational rollout
control systems, the Touchdown Zone, Mid, and Rollout RVR reporting systems are normally
required and are controlling for all operations. If one of these RVR reporting systems is
temporarily inoperative, these operations may be initiated and continue using the two
remaining RVR reporting systems. Both RVR reports are controlling.
d. Pilot Qualifications. The minimums prescribed in subparagraphs a. and g. are authorized for only
those pilots-in-command and seconds-in-command who have completed the certificate holder's
approved Category III training program and who have been certified as qualified for Category
IIIa, or Category IIIa and Category IIIb operations, by one of the certificate holder's check airmen
properly qualified for Category III operations or an CAAC inspector. No pilot-in-command shall
be authorized to conduct Category III operations in a helicopter unless that pilot has had at least
100 hours as pilot-in-command in the specific make and model helicopter used in the Category III
operation.
e. Operating Limitations. The certificate holder shall not begin the final approach segment of an
instrument approach procedure, unless the latest reported controlling RVR for the landing
runway is at or above the minimums authorized for the operation being conducted. If the aircraft
is established on the final approach segment and the controlling RVR is reported to decrease
below the authorized minimums, the approach may be continued to the AH/DH applicable to the
operation being conducted. Unless all of the following conditions are met, the certificate holder
shall not begin the final approach segment of a Category IIIa instrument approach when the
controlling RVR for the landing runway is reported to be less than Category II minimums, or
begin the final approach segment of a Category IIIb instrument approach when the controlling
RVR for the landing runway is reported to be less than Category IIIa minimums:
(1) The airborne equipment required by subparagraph b. is operating satisfactorily.
(2) All required elements of the Category III ground system, except sequence flashing lights, are
in normal operation. For ILS operations, a precision or surveillance radar fix, a NDB, VOR,
DME fix, or a published minimum GSIA fix may be used in lieu of an outer marker.
(3) All Category III operations using minimums below RVR 600 (175m) shall be conducted to
runways which provide direct access to taxi routings equipped with serviceable taxiway
centerline lighting which meets ICAO criteria for Category III operations.
(4) The crosswind component on the landing runway is 10 knots or less.
f. Missed Approach Requirements.
(1) For Category IIIa approaches with a fail-passive flight control system, a missed approach
shall be initiated when any of the following conditions exist:

(a) At the DH, if the pilot has not established sufficient visual reference with the touchdown
zone or touchdown zone lights to verify that the aircraft will touchdown in the
touchdown zone.
(b) If, after passing DH, visual reference is lost or a reduction in visual reference occurs
which prevents the pilot from continuing to verify that the aircraft will touchdown in the
touchdown zone.
(c) When a failure in the fail-passive flight control system occurs prior to touchdown.
(d) If the pilot determines that touchdown cannot be safely accomplished within the
touchdown zone.
(e) When any of the required elements of the ground system becomes inoperative before
arriving at DH. However, Category III approaches and landings may be continued if
