ENGINE OUT TAXI
Refer FCOM 3.
Engine Out Taxi (EOT) operations have the potential to save fuel and to reduce carbon emissions.
During EOT operations, the crew's attention should be focused on taxiing the airplane. Distractions should be kept to a minimum.
High bypass engines require warm-up prior to applying take-off thrust and cool down prior to shutting down. If the engine has been shut down for several hours, it is desirable to operate at as low a thrust setting as practical for several minutes prior to take-off.
If an engine is shutdown during taxi in after flight, the crew must be aware of hydraulic, electrical, and braking system requirements, particularly any degraded system operation due to enroute failures.The APU should be operating while taxying with an engine shutdown. If possible, make minimum radius turns in a direction that puts the operating engine on the outside of the turn. In operational environments such as uphill slope, soft asphalt, high gross weights, congested ramp areas, and wet/slippery ramps and taxiways, taxi with both engines operating.
