+        A crossbleed engine start normally requires an Air Start Unit to be connected to the aircraft to start the first engine. This is not currently simulated in the A32NX.

 ### Overhead Bleeds Configuration
 
 `ENG BLEED` for the receiving engine needs to be switched `OFF`. This is to prevent the bleed air from the running engine from escaping through the receiving engine
