# Taxi In ### SINGLE ENGINE TAXI After one minute operation at idle, and when clear of runway, complete the After LAnding checklist, then shut down No. 3 engine. Reduce electrical loads and configure systems as follows before shutting down No. 2 engine: * Ensure essential power is selected to an operating generator. * Ensure right pack is off if APU generator is not being used * Leave gasper fan off. * Ensure both system B hydraulic pumps on. * Open brake interconnect. * Crossfeed as necessary to maintain fuel load limits. * Turn off boost pumps as necessary to reduce electrical loads. * Close brake interconnect after parked at gate with brakes set. ### APU START Normally, do not start the APU after landing when the outside air temperature is between 40F and 75F unless electrical ground power is not available. If the APU is to be used, start it before gate arrival. Allow one minute of operation before using the APU for bleed air. ### AIR CONDITIONING AND BLEED AIR CONTROLS After the APU has operated for approximately one minute with its generator frequency stabilized, place No. 2 bleed switches to OPEN. This provides air to both packs from the APU. Leave both packs on while taxiing and at ramp. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
