FLIGHT CREW TRAINING MANUAL
If ATC clears the aircraft to maintain a specific heading after takeoff, turn the FCU HDG selector to disarm the NAV. The current aircraft heading will be displayed on the FCU and the ND, and the flight crew can then set the cleared heading. Once airborne, and above 30 ft, RA, RWY TRK engages. To apply the clearance, the FCU HDG knob should be pulled. Once cleared to resume the SID, a HDG adjustment may be necessary to intercept the desired track for NAV capture.
TAXI WITH ONE ENGINE SHUTDOWN
Criteria: SA
5 Applicable to: MSN 0045-1718
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 crew should be aware of the following:
? It is recommended to retain the use of engine 1 during taxi to maintain the green hydraulic system for normal braking and NWS.
? Before releasing the parking brake, the yellow electrical pump will be set ON to pressurize the yellow hydraulic system (ALT/PARK BRK) and avoid PTU operation. The crew will check the hydraulic yellow accumulator pressure.
? 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 and thus generate a further 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).
? The use of APU is recommended but the APU bleed should be switched off to avoid ingestion of exhaust gases by the air conditioning system.
? Before ENG2 start,
‐ The yellow pump is set off to check correct operation of the PTU
‐ APU BLEED is set back to ON for ENG2 bleed start.
