What should be done if external power is available on the ground?

Explanation:
When ground power is available, use it and keep the APU off. External power provides the electrical and environmental support the aircraft needs without burning fuel, so it’s more economical and reduces wear on the APU. The APU is there for times when external power isn’t available or can’t meet the load, or when starting engines. So the best practice on the ground is to connect to external power and not run the APU.
