To my understanding, AOM 2-12.2 says: The APU "MAY NOT" be started during refueling/defueling.
'MAY NOT' still sound optional to me, and I have been doing it all the time, who knows how long it takes for those fuelers to slack off down there.
Then next sentence says: 'DO NOT' start the APU during refueling/defueling if an APU shutdown or a failed APU start occurred.
That I wont mess with! But it also proves that above is optional. Just my 2 cents.
