Which fixed-wing condition requires starting equipment plugged in?

Starting equipment plugged in is all about having immediate power available to start the engines and run flight systems. In the highest readiness state, the aircraft is kept on external power so it can be launched within minutes without waiting for onboard power to come up. This means the starting equipment (GPU/start cart) must be connected to ensure a rapid, reliable start and full electrical support for the aircraft’s systems at the moment of ignition. That’s why the 5-minute alert condition is the one that requires starting equipment plugged in. The other readiness levels assume the aircraft can start with its own power sources coming online or don’t demand external power to be connected at all times, so plugging in the starting equipment isn’t a mandatory requirement for those states.
