.
Set the TCAS selector to TA ONLY.
During the approach if a “breakout” is directed by ATC: The PF will:
.
Immediately disconnect the autopilot -- do not disconnect the autothrottles.
.
Do not push TOGA.
.
Immediately manually fly the aircraft to the assigned heading and altitude (do not descend at a rate greater than 1,000 FPM).
.
Do not change aircraft configuration (gear or flaps) until after established on the new heading.
.
Autopilot may be re-engaged after established on new heading.
.
Aircraft may be reconfigured (gear, flaps, and speed) as desired after established on the new heading.
The PM will:
.
Acknowledge ATC instructions.
.
Set the directed heading and put the FGS in HDG SEL mode.
.
Set and arm the directed altitude in the FGS.
.
Set the FGS VERT SPD to 1,000 FPM up or down as required.
.
Reconfigure the aircraft as called for by the PF.
.
Change the TCAS mode back to TA/RA as appropriate.
Monitored ILS Approach Procedures
Preflight
Check the Aircraft Status Annunciator and the logbook to determine the lowest approach category the aircraft will be capable of. Perform the receiving aircraft checklist with special attention to those items and functions. which will be necessary for the category of approach planned.
Accomplish an autoland preflight test during the receiving aircraft check.
Aircraft Status Annunciator
One status annunciator will be located on the Captain’s instrument panel. It will indicate the current status of the aircraft equipment as follows: CAT II (Black) - The aircraft is authorized Cat I and Cat II approaches but not autoland to touchdown. NOT CAT II (Red) - The aircraft is authorized Cat I approaches but not autoland to touchdown. Note: Only qualified CAL maintenance personnel may change the status annunciator.
Enroute
The flight crew should monitor weather at the destination and determine as early as possible the approach to be flown. In addition to reviewing the approach, the flight crew should review the required equipment list for the type of approach to be flown and the Monitored Approach Briefing Guide.
Approach Minimums
LOWEST AUTHORIZED APPROACH MINIMUMS
Cat I Cat II
RVR (Feet) ≥ 1800 ≥ 1200
DA(H) (Feet) Barometric Altimeter ≥ 200 feet above TDZE Radar Altimeter ≥ 100 feet above TDZE (Or inner marker if RA not authorized)
Runway Visual Range (RVR)
.
Controlling RVR - Used to determine operating minima for the approach.
The flight crew is prohibited from beginning the final approach segment unless the last report indicated all controlling RVR’s are at or above the minimums for the approach. All RVR transmissometer’s that are controlling are required. If the flight crew receives a controlling RVR report that is below minimums after established on the final approach segment, they may continue the approach until DA(H). On a Cat I or Cat II approach, the Captain may continue below DA(H) if (s)he determines adequate visual reference for the type of approach exists.
.
Advisory RVR - Does not constitute minima for the approach and provides the flight crew information only. Advisory RVR transmissometer’s may or may not be required.
RVR Transmissometer Requirements
Cat I Cat II
TDZ Required & Controlling Required & Controlling
MID Not Required1 , Advisory Not Required2 , Advisory
Rollout Not Required, Advisory Not Required2 , Advisory
1 - Cat I: MID RVR may be substituted for TDZ if TDZ is not reporting. 2 - Cat II: If TDZ RVR is below 1600, advisory MID or Rollout RVR required.
Localizer Tracking
Flight crews should closely monitor autoflight systems and ILS raw data during the approach to ensure proper localizer tracking. The following operating practices, when conditions permit, will significantly improve localizer tracking and provide touchdown closer to runway centerline.
.
Prior to approach, check rudder and aileron trim before engaging autopilot.
.
Maintain symmetrical thrust on both engines throughout the approach.
.
When air traffic control will permit, intercept the localizer at an angle not greater than 45 degrees. Capture the localizer not less than 8 miles from runway threshold. Capture the localizer with flaps 15° and at a speed no greater than 170 knots. Capture the glideslope at or above 1,500 feet AGL.
.
Aircraft should be stabilized on localizer and glideslope before passing outer marker or a soon as possible after passing the final approach fix.
