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.
