For the moment, my choice is to put both PACKs on as early as practicable:
- no need to evaluate stuff
- recovers all the options that might become available or needed later
- come back from the "green" PROC to a configuration that was assumed when ABN PROC and ECAM designers did their work.
My $0.02:
If the PACKS had been ON forT/O, the ECAM/FCOM doesn't tell you to turn OFF the affected side PACK does it?
