1. A method for operating an aircraft having a first engine and a second engine, the method comprising:
determining a plurality of taxi paths for the aircraft to take, each path comprising a takeoff taxi path or a landing taxi path;
determining a zone for each taxi path where, when the taxi path is a takeoff taxi path, the first engine is on and the second engine is turned on, to allow the second engine to be started and to warm up and thermally stabilize before takeoff, and where, when the taxi path is a landing taxi path, the first engine remains on while the second engine is turned off, to allow the second engine to thermally stabilize after landing;
determining whether the second engine can be turned on along the takeoff taxi path and whether the second engine can be turned off along the landing taxi path;
providing a signal indicating the zones;
turning on the second engine along the takeoff taxi path when it is determined that the second engine can be turned on; and
turning off the second engine along the landing taxi path when it is determined that the second engine can be turned off.
