I presume that you do not mean the Airbus in iOS Aerofly FS? IPACS have said that they will not update it anymore.
well.. is not only for Airbus (Even if I use it a lot), it's for all planes of the game. I think that it is not difficult to add, because the ILS system already exists. And it would allow to see better the ILS indicator on small screens. I have an iPhone 5S and i use the flight information menu.
