Why are you doing this now if additional changes may be needed in several years’ time?
The modern navigation capability of today’s aircraft offers the opportunity to provide operational and environmental benefits, however there are constraints as to how much we can change right now (this is explained in Part A). We want to realise those benefits as early as possible, hence we are not allowing the constraints to slow the development of areas where they are less relevant.
Additional changes required in later phases will only be made where they allow us to realise even more benefit.
