LVP Failure Procedures (CP2 Appendix 2)

Aircraft Equipment Failures after Commencing Approach
  CAT 3B CAT 3A CAT 2 CAT 1 NP
Lowest Minima No DH / 75 m 50 ft / 200 m 100 ft / 300 m 200 ft / 550 m 250 ft / 800 m
required ASA LAND 3 LAND 2 not required
       
After selection of Approach Mode
Engine Failure Disconnect Autothrottle
Control with thrust and rudder
If ASA indicates LAND 3 or LAND 2, continue with 3A minima If ASA indicates LAND 3 or LAND 2, continue for CAT 2 no effect - continue
       
Prior to Outer Marker (or equivalent position)
TDZ RVR below required minima continue to Outer Marker (or equivalent position)
       
At Outer Marker (or equivalent position)
TDZ RVR below required minima Go Around
       
After Outer Marker (or equivalent position)
TDZ RVR below required minima no effect - continue
Ground equipment or lighting failure reducing airfield LVP status Revert to declared status.
Go Around if status below that required for current RVR.
(see Airfield Equipment Failures)
Autopilot disconnect Go Around or revert to CAT 1 no effect - continue
ASA Failure Go Around or revert to CAT 1 PF ASA fails:
Go Around or revert to CAT 1
Change of ASA status LAND 3 - Continue
LAND 2 - revert 3A
NO AUTOLND - revert CAT 1
LAND 3/2 - Continue
NO AUTOLND - revert CAT 1
Autothrottle failure Continue - use manual throttle
       
At or below Decision Height
TDZ RVR below required minima Land if Visual
Engine Failure Land - If NO AUTOLND displayed
disconnect autopilot and Go Around
(manual landing may be safer)
no effect - continue
Change of ASA status
Autopilot disconnect Go Around
(manual landing may be safer)
       

Aircraft Equipment Failures

Dispatch (MEL Section 4)
  CAT 3B CAT 3A CAT 2 CAT 1 NP
required ASA LAND 3 LAND 2 not required
autopilots 3 2
autopilot disengage switches both
ASA 1
GA switches both
electrical systems 2 (includes APU)
Rudder Ratio required
control wheel trim switches both 1 (PFs)
horizontal stabiliser primary trim channels both 1
flight spoilers all 1 pair may be INOP - see MEL notes
antiskid system required not required
rudder pedal nose-wheel steering required not required
IRS in NAV 3 2
ADI (supplied by different SG) 2 1 plus Standby ADI
AFDS mode display operative on both ADI not required
ILS receivers 3 2 (including Centre) Centre ILS
Radio altimeters 3 2 - see MEL notes 1 - see MEL notes
       
Prior to Commencing Approach (CP2)
  CAT 3B CAT 3A CAT 2 CAT 1 NP
required ASA LAND 3 LAND 2 not required
autopilots 3 2 1
ASA 2 1 (PFs)
ADC/ADIRU 2
electrical systems 3 (includes APU)
[see note 1]
2 (includes APU)
hydraulic systems 3
IRS in NAV 3 2 not required if standby ADI and standby compass serviceable
ADI (supplied by different SG) 2 not required if standby ADI serviceable
AFDS mode display operative on both ADI not required
ILS receivers 3 2 1 not required
Radio altimeters 3 2 not required
Autothrottle required not required
       

Note 1: Three Electrical systems reflects the requirement to have autoland bus isolation; however, the ASA cannot annunciate LAND 3 unless bus isolation has occurred.
