Q
What happens to the ELACs if all ADIRS were lost?
A
“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.

What is the function of the cabin fans? When do we select them off?
2 Cabin fans are installed to recycle cabin air into the mixing unit and back and therefore save fuel
They may be selected off only in response to an ECAM procedure.

With BLOWER and EXTRACT pbs in AUTO, how does the system operate?
When both pushbuttons switches are on AUTO:
- On the ground before the application of TO power, the ventilation system is in the OPEN circuit configuration (closed configuration when the skin temperature is below the ground threshold)
- On the ground after the application of TO power, and in flight, the ventilation system is in the closed circuit configuration.
FCOM/DSC/21/30/60/OVERHEAD PANEL
237
How is the equipment cooled in each configuration?
Closed circuit: the equipment is cooled by blown air through a skin heat exchanger
Intermediate : the equipment is cooled by blown air through a skin heat exchanger plus partially exhausted
overboard.
238
With both BLOWER and EXTRACT pbs in OVRD, what are the positions of the INLET and
EXTRACT valves?

* EXTRACT valve partially OPEN
FCOM/DSC/21/30/20/ABNORMAL OPERATION
239
What fan is OFF if BLOWER and EXTRACT pbs in OVRD position?
* BLOWER fan OFF
* EXTRACT fan ON
Note: all valves are closed (except extract valve) and air from air-conditioning system is added to ventilation air and directed overboard through the skin air extract valve

Is Air Conditioning ever introduced into the Avionics Compartment?
Yes – In the SMOKE configuration or abnormal configuration.
FCOM/DSC/21/30/20/ABNORMAL OPERATION

245
What are the primary differences between a manual and a normal automatic start?
* Automatic start interruption and auto-crank are not available during manual start.
* In manual start the FADEC will only abort the start if on ground and EGT limit is exceeded before N2 =50%
FCOM/DSC/70/80/40/MANUAL STARTING
246
What is the FADEC authority during manual start?
FADEC has a limited authority:
• Opening the start valve (if ENG MODE is set to IGN/SART and MAN START
switch is pressed)
•Opens the HP shut off valve and operates both igniters when crew sets ENG MASTER to ON.
•Closes the engine start valve, and cuts off the ignition when N2 reaches 50% (63% on NEO)
In flight, FADEC has no authority to abort a manual start.
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
247
Will the start valve automatically close during a manual start?
Yes, at 50% N2. (63% on NEO)
FCOM/DSC/70/80/40/MANUAL STARTING
248
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?
1. Aircraft battery supplying at least one IRS
2. 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.
FCOM/DSC/34-NAV/10/20/OVERHEAD 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

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.

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.
BKUP SPD/ALT PB use and FLY THE GREEN
FCOM/PRO/ABN/NAV/NAV ADR 1+2(1+3)(2+3) FAULT/NAV ADR 1+2+3 FAULT
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.
