TAXI WITH ONE ENG SHUTDOWN A330
Brake life and fuel savings may govern company policy on permitting aircraft to taxi with one engine shut down.
However, if taxiing out with one engine shutdown, the flight crew should be aware of the following:
It is recommended to retain the use of Engine 1 during taxi to maintain the accumulator pressure of the blue hydraulic system.
If taxi is performed with Engine 2, the flight crew should check the accumulator pressure of the blue hydraulic system.
Slow or tight turns in the direction of the operating engine may not be possible at high Gross Weights.
It is not possible for ground personnel to protect the engine against fire, when the aircraft moves away from the ramp.
The remaining engines should be started with sufficient time for engine warm-up before takeoff
Any faults encountered during, or after, starting the remaining engine may require a return to the gate for maintenance. This could result in an additional departure delay.
Taxi with one engine shut down may require higher thrust than usual. Caution must, therefore, be exercised to avoid excessive jet-blast and the risk of Foreign Object Damage (FOD).
It is recommended that the flight crew use the APU. However, APU bleed should be switched off, in order to avoid ingestion of exhaust gases by the air conditioning system.
