What other considerations are there? The ground horn warning will sound after a certain time?
Is there a time frame where the power needs to be restored before losing all of the FMC data input?
If ground power cannot be restored, it's best to start the APU.
more in the nuisance category.
I suppose today, more and more time is spent on ground power rather than on the APU. If the APU is inop, it is a proper nuisance.
