Engines can start with only External power?

[Guest Robin.B]

Dear Captains,I just tried this on the 747-400, just for the heck of it, and was very surprised by the results. I loaded a cold & dark cockpit. Nothing is on at all. Just the default Cold and dark cockpit. Then I turned on the Battery, and External power. Only these two. Then I pulled the start switches and fed in fuel. The engines started fine??Is this normal behavior?Thanks!Best Regards,Robin Bilgil

Yes, that's normal... because you're also getting "Ground Pneumatic Air".- Bill
