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.

FCOM/DSC/21/20/40/OVERHEAD PANEL

116
Q

When out of the AUTO position, what is different?

FCOM/DSC/21/20/40/OVERHEAD PANEL

117
Q

What depressurizes the aircraft in case of residual pressure after landing? How does it work?

A

Residual pressure control unit (RPCU), it automatically opens outflow valve when:
• Outflow valve not fully open, and
• Both CPCs are failed, or manual mode is selected, and
• Aircraft on ground, and
• All engines are shutdown or all ADIRS indicate airspeed below 100 kts.

FCOM/DSC/21/20/20/RESIDUAL PRESSURE CONTROL UNIT (RPCU)

118
Q

What protects the airframe from excessive cabin differential pressure?

A

2 independent pressure safety valves stop the cabin pressure going too high (8.6 PSI above ambient) or too low (1 PSI below ambient)

FCOM/DSC/21/20/20/SAFETY VALVES

119
Q

How many motors does the outflow valve have?

FCOM/DSC/21/20/20/OUTFLOW VALVE

120
Q

What is the ABORT mode in auto cabin pressurization and what does it do?

A

If the aircraft does not climb after takeoff, the abort mode prevents the cabin altitude from climbing. Cabin pressure is set back to the takeoff altitude +0.1 PSI

FCOM/DSC/21/20/30/AUTOMATIC PRESSURE CONTROL MODE

121
Q

What monitors and controls the pneumatic system?

A

Two Bleed Monitoring Computers (BMC 1 &BMC 2) control and monitor the operation of the pneumatic system.

The aircraft has 2 similar bleed air systems.
Each system is designed to:
- select the compressor stage to use as a source of air
- regulate the bleed temperature
- regulate the bleed air pressure

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

FCOM/DSC/36/10/20/GENERAL

122
Q

If one BMC fails, can the other take over?

A

If one BMC fails, the adjacent BMC takes over the monitoring of the bleed system to issue the following ECAM warnings if necessary:

  • Overpressure
  • Overtemperature
  • Wing Leak

Nevertheless, the associated FAULT light on the AIR COND panel is lost, and the associated bleed valve does not close automatically.

ENG BLEED LEAK warning is lost for the associated engine, as is also the APU BLEED LEAK warning is BMC1 has failed.

Q

When is HI flow rate automatically selected regardless of the Pack Flow selector switch position?

FCOM/DSC/21/10/20/HOT AIR PRESSURE REGULATING VALVE

136
Q

What is the function of the HOT AIR pb?

A

Temperature regulation is optimized via the hot air pressure regulating valve, and the trim air valves that add hot air, tapped upstream of the packs, to the air coming from the mixing unit.

FCOM/DSC/21/10/10/GENERAL

137
Q

How many Air-Conditioning System Controllers (ACSC) are there?

A

2 ACS controllers to monitor the temperature of 3 zones (cockpit, forward cabin, aft cabin)

FCOM/DSC/21/10/30/TEMPERATURE REGULATION

138
Q

How many lanes on each ACS Controllers? And how do they operate?

A

2 lanes (one active and one standby) if both fail the related pack is lost.

FCOM/DSC/21/10/40/GENERAL

139
Q

Describe how the air conditioning system controls the temperature in each zone.

A
  • Pack output temperature regulation is determined by the zone requiring the coldest air
  • Hot air is added to the individual zones by the trim air valves to maintain the desired zone temperatures

FCOM/DSC/21/10/30/TEMPERATURE REGULATION

140
Q

If an air cycle machine (ACM) fails, what occurs?

FCOM/DSC/21/10/40/AIR CYCLE MACHINE FAILURE

141
Q

What happens to the pack flow control valves during engine start? (Normal engine start using APU)

A

When engine Mode selector set to IGN, both pack flow control valves close.

They remain closed when

  • MASTER sw set to ON (or MAN START pb set to ON)
  • The start valve is open
  • N2 < 50%

On ground, reopening of the valves is delayed for 30 s to avoid a supplementary pack closure cycle during second engine start.

FCOM/DSC/21/10/50/CONTROLS ON OVERHEAD PANEL

Q

After engine start with the APU BLEED pb ON, what source is supplying bleed air to the packs?

Q

Will the batteries completely drain if you leave the BAT switches in AUTO after AC power is removed?

A

A battery cut-off logic prevents the batteries from discharging completely when the aircraft is on the ground.

FCOM/DSC/24/20/OVERHEAD PANEL

FCOM/DSC/24/20/OVERHEAD PANEL

153
Q

What is the function of the BUS TIE pb in the AUTO position?

A

The bus tie contactors (BTCs) automatically open or closed to maintain power supply to both AC BUS 1 & 2

One contactor is closed when:

  • One engine generator supplies the associated AC BUS, and
  • APU GEN or EXTERNAL power supplies the other side.

Both contactors are closed:
During single-engine operation or operation on APU or external power

FCOM/DSC/24/20/OVERHEAD PANEL

No, only on ground and speed below 100 knots (only then the batteries will be connected to the DC BAT BUS).

FCOM/DSC/24/10/30/30/EMERGENCY GENERATION AFTER LOSS OF ALL MAIN GENERATORS

155
Q

In emergency configuration with the emergency generator online can you start the APU in flight?

A

APU start is not available for 45 seconds after the loss of both engine generators. This delay prevents any interference with emergency generator coupling. If the APU is available, the APU may be started when below FL250.

FCOM/DSC/28/10/30/FUEL FEED SEQUENCE

175
Q

5 pumps total

FCOM/DSC/28/10/30/ENGINE FEED

176
Q

When the center tank fuel pumps operate in auto mode when do they come on? When do they stop?

A

Not applicable to Flyadeal Aircraft. Flyadeal has Center tank transfer valves with a different logic.

With the MODE SEL PB-SW in AUTO:
Control of the center tank transfer valves ins automatic:
- They open if the associated inner tank is not full (and allow 500kg inner tank fuel to be used,
- They stop automatically 5 min after the center tank low level is reached.

FCOM/DSC/28/20/OVERHEAD PANEL

OLD ANSWER:
• On For 2 minutes after BOTH engines are started (if slats are UP will continue to run)
• After slat retraction
• They stop 5 minutes after center tank low level is reached
• They stop when inner tank overfill from fuel returned from IDG cooling SYS until 500 kg is burned
from inner tank

177
Q

What will cause a FUEL MODE SEL PB FAULT light?

FCOM/DSC/28/10/60/FUEL RECIRCULATION SYSTEM

182
Q

If the IDG return fuel fills the wing tanks, what occurs?

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)

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.
