BD,
Will EFD2 sectors communicate electronically with other EFD2 sectors?
If so will this be confined to the same LAG, the same unit or will it operate between EFD equipped units?
Will EFD2 communicate electronically with iFACTS?
Will it communicate electronically with iTEC? Or will there still be a requirement for FRED?
Will EFD2, iTEC and iFACTS all communicate electronically with EFPS? Or will FRED still be required as a backup, (sorry, 'fallback')?
