A320 Early Engine Shutdown?
I regularly pax on A320s and their derivatives. I've noticed a few times now that after landing if there is a delay in parking at a stand it sounds as if the engines are shut down - the APU coming on at the same time (as indicated by the usual flicker in the cabin lights) - and then the a/c finishes its taxi in that state. Is the APU being used to taxi the aircraft? Or is there some element of the main engines that is shut down but they are still capable of moving the a/c at low speed?
