What does the green AVAIL message on ECAM indicate?

• The engine is ready to re-start

• The start sequence has ended and the engine is at idle or above

• The pneumatic flow and pressure is correct to start the engine

   

After the Auto thrust is engaged manually or automatically, when will it be Active?

• In Take off

• all the time

• When the throttles are set in climb detent after TO

 

What does the  ENG 1 (2) OIL FILTER CLOG  message on ECAM indicate?

• Malfunction in the  oil filter  circuit

• The filter is partially contaminated

• Filter contaminated in by-pass condition

The safe source of the ignition system comes from…

• AC main bus nbr 1

• AC Essencial Bus

• DC essencial bus

The unit whose role is to interpret, analyze, and save the vibration data to perform trim balance is

• The prognostic health and monitoring unit (PHMU)

• The electronic engine control (EEC)

• The engine interface unit  (EIU)

   Engine bearing compartments contain tapered roller on:

•   No. 2 and 3 roller bearing and are used to support FDGS.

• No. 1 and 2 and are used to support the fan.

•   No. 1 and 1.5 and are used to support the fan rotor and FDGS.

During starting, the servo Fuel pump is don’t used because:

• The pressure is not enough to control the air system actuators.

•    The control the air system actuators aren´t used.

•   To control the fuel nozzles.

  During a normal engine shutdown, the Master Lever controls the LPSOV to close and sends a shutdown signal to:

•   EIU to send signal to HPSOV.

• EEC to close HPSOV.

• Directly to HPSOV.

   Abnormal shutdown is initiated in case of a Thrust Control Malfunction (TCM) event; the EEC send control signal to:

• TCM TM to direct fuel pressure to the back side of the HPSOV

•    TCM TM to direct oil pressure to the back side of the LPSOV in flight.

• TCM TM to direct oil pressure to the back side of the LPSOV on ground

The PMA will supply power to the EEC above

• 60% of the N2

• 10% of N1

• 10% of the N2
