     The A320neo needs pressurized air to start the engines. This pressurized air is usually generated by the APU for the start of the engines. This is called bleed air, as it is a byproduct of a running jet engine where pressurized air is taken from the engine to be used on other systems.
 
     **To start the engines, you need to have the APU available and the APU Bleed ON.**

     Also, in very rare cases the gate or a mobile ground unit has pressurized air to be connected to the aircraft so the first engine can be started without APU. This is usually done when the APU is INOP. Microsoft Flight Simulator does not provide this option.
