What happens to the ELACs if all ADIRS were lost?
“We lose ELAC functions” - GACA answer
If all ADRs are lost, ELACS trigger NAV ADR DISAGREE ECAM caution.
Flight controls revert to alternate law without high or low-speed protection. The situation is latched until ELACs are reset on the ground.
The ADIRS supply information to the ELACs so some parts of the ELACs may be lost but no clear statement says the ELAC functions are lost.

- regulate the bleed temperature
- regulate the bleed air pressure
Each BMC receives information about the bleed pressure, temperature and valve position.

On ground, FADEC has authority only to abort a start if EGT exceeds limit before N2 reaches 50% (63% on NEO)
FCOM/DSC/70/80/40/MANUAL STARTING
Will the start valve automatically close during a manual start?
Yes, at 50% N2. (63% on NEO)
FCOM/DSC/70/80/40/MANUAL STARTING
When a manual ENG start is recommended?
1-After aborting a start because of:
• Engine stall
• Engine EGT over limit
• Low start air pressure
2-When expecting a start abort, because of:
• Degraded bleed performance (hot conditions or high elevation airports)
• An engine with reduced EGT margin (hot conditions or high elevation airports)
• Marginal performance of external pneumatic power.
• Intermittent ECAM ENG 1(2) ING A(B) FAULT, during first start of the day

What does ON BAT light indicate?
- Aircraft battery supplying at least one IRS
- Comes on for a few seconds at beginning of a complete IRS alignment
Note: When the aircraft is on the ground and if at least one ADIRU is supplied by aircraft batteries:
- An external horn sounds
- the ADIRU and AVNCS light comes on amber on the EXTERNAL POWER panel.

How do you fast align an IR?
Set the IR mode selectors to OFF then, back to the NAV mode within 5 seconds.
Note: A fast alignment resets the ground speeds and some internal filters to 0, but IRSs do not estimate the aircraft position.
FCTM/PR/NP/SOP/60/ADIRS OPERATIONS
Note: A fast alignment must be performed if a complete alignment is not necessary and the difference between the IRS and FMGC position is at or above 5 NM

What is indicated by a steady IR FAULT light?
The respective IR is lost.
FCOM/DSC/34-NAV/10/20/OVERHEAD PANEL
What is indicated by a flashing IR FAULT light?
The attitude and heading information may be recovered in ATT mode.

What is indicated by a steady ADR FAULT light?
Fault detected in Air Data Reference part.
FCOM/DSC/34-NAV/10/20/OVERHEAD PANEL
What information does IR supply?
- Attitude
- Flight Path Vector
- Heading
- Track
- Accelerations
- Angular Rates
- Ground Speed
- Aircraft Position
FCOM/DSC/34-NAV/10/10/GENERAL
What information does the ADR supply?
- Barometric altitude,
- Airspeed
- Mach
- Angle of Attack
- Temperature
- Overspeed Warnings
FCOM/DSC/34-NAV/10/10/GENERAL
What would be missing on Captain’s PFD if IR1 failed or was turned OFF? How could this be recovered?
Attitude & Heading information would be lost on Captains PFD.
Follow ECAM NAV IR 1 FAULT procedure
Selecting CAPT 3 on the EIS Switching panel ATT/HDG selector would recover the missing information.
FCOM/PRO/ABN/NAV/NAV IR 1(2)(3) FAULT
When do we need to select ATT and what must be done after selecting it?
If the IR fault light is flashing, the IR may be recoverable in ATT mode.

With the loss of ADR 1, what would be lost on Captains PFD? How would you recover the lost data?
Airspeed and Altitude
Follow ECAM procedure NAV ADR 1 FAULT
Selecting CAPT 3 on the EIS Switching panel AIR DATA selector would recover the missing information.

How would you recover from two or more lost ADRs?
Follow ECAM NAV ADR 1+2(1+3)(2+3) FAULT or NAV ADR 1+2+3 FAULT
In case of 2 failed ADRs, EIS SWTG to display operating ADR on either Captain or F/O side.
In case of 3 failed ADRs, select all ADRs OFF.

Good to know:
Loss of ADR 1 leads to loss of EGPWS
Loss of ADR 2 leads to both Baro reference channels driven by the same FCU channel, so they should be checked.
Loss of 2 ADR leads to alternate law.
Loss of ADR 1+3 leads to landing gear safety valve controlled closed. It must be lowered by gravity extension.
Loss of all ADR is ECAM NAV ADR 1+2+3 fault. Complete ECAM then QRH ALL ADR OFF paper checklist. Most notable is CPC must be manually controlled, alternate law, and gravity gear extension. Of lesser concern is the loss of stall warning, rudder travel limiter is frozen until slat extension, and loss of auto flap retraction.
