A330 OEB

Question 1

ERRONEOUS VERTICAL PROFILE DURING RNAV, LOC AND LOC B/C APPROACHES

Answer 1

Check position of the MAPT on the MCDU
• RNAV approach (labelled RNV on MCDU):
- MAPT at rwy threshold: FINAL APP can be used
- MAPT not located at Runway threshold:
. Fly Selected vertical profile (FPA)
. Disregard VDEV symbol
. Crosscheck descent path using altitude/distance

Approach labelled “GPS” on MCDU can be flown in FINAL APP mode regardless of MAPT position

• LOC approach:
- MAPT at rwy threshold: VDEV symbol can be used to fly the vertical flight path in selected mode
- MAPT not located at Runway threshold:
. Fly Selected vertical profile (FPA)
. Disregard VDEV symbol
. Crosscheck descent path using altitude/distance

Question 2

A330 - IR FAILURE OR ATT FLAG ON PFD

Answer 2

• All ADIRU operative before failure:
NAV IR 1(2)(3) FAULT or ATT flag on CAPT (F/O) PFD:
IR (affected) pb…………………………………………………………….OFF
ADR (corresponding) pb……………………………………………..OFF
IR (affected) MODE rotary selector…………………………….OFF
The IR rotary selector is set to OFF in order to de-energize the ADIRU, the OFF light of the IR pb and ADR pb will go off.
AIR DATA SWTG…………………………………….CAPT (F/O) ON 3
ATT HDG SWTG…………………………………….CAPT (F/O) ON 3

• 1 ADIRU already disconnected before failure:
NAV IR 1+2(1+3)(2+3) FAULT or ATT flag on PFD:
IR (affected) pb…………………………………………………………..OFF
ADR (corresponding) pb……………………………………………OFF
IR (affected) MODE rotary selector…………………………..OFF

CAUTION Setting the IR mode rotary selector to OFF is an irreversible action. Both PF and PNF must clearly identify the corresponding selector.

Question 2

NAV ADR 1+2+3 FAULT ECAM WARNING UNDUE ACTIVATION

Answer 2

DO NOT use the ECAM
Refer to QRH/ABN-34 ADR 1 + 2 + 3 FAULT

BUSS is not installed on the aircraft and this ECAM is erroneous.

Question 3

ERRONEOUS RADIO ALTIMETER (RA) HEIGHT INDICATION

Answer 3

Early THR IDLE and FLARE mode engagement on ILS
‐ Go-Around
or
‐ AP and FD OFF, continue raw data ILS or visual

Question 4

AIR DATA/ATT FLAGS ON CAPTAIN PFD/ND UPON ELEC EMER CONFIG OR ENG ALL ENG FLAME OUT

Answer 4

if the following simultaneously occurs:
‐ ECAM ELEC EMER CONF or ENG ALL ENG FLAME OUT
‐ Air data/ATT red flags are displayed on Captain PFD/ND

STBY INST………………………………………………………………USE
AIR DATA SWTG…………………………………………CAPT ON 3
ATT HDG SWTG………………………………………….CAPT ON 3

If Air data/ATT recovered from ADIRU 3: Apply ELEC EMER CONF or ENG ALL ENG FLAME OUT ECAM/QRH procedure

If Air data/ATT not recovered from ADIRU 3 The ADIRU 1 and 3 are lost

Question 6

LOSS OF AP AND A/THR ASSOCIATED WITH ALTERNATE LAW REVERSION

If AP and A/THR are automatically disconnected with flight controls reverting to alternate law

Answer 6

Do not engage the AP and the A/THR, Do not follow the FD orders

ALL SPEED INDICATIONS……………………………….X-CHECK

If unreliable speed indication is suspected:
UNRELIABLE SPEED INDIC/ADR …………………………APPLY

If at least two ADR provide reliable speed indication and the aircraft is stabilised on the intended path:
AP/FD and A/THR……………………………………………As required
