A320 Managed versus Selected FG modes
For the Airbus gurus amoung us.
The concept of Managed and Selected modes for the Airbus are quite straight forward however in relation to a ILS approach what would LOC and GS be classified as?.
The FCOM doesn't seem very clear. The reason for the question is if in the unlikely situation with NAV ACCUR LOW (and a negative nav accuracy check) is LOC and GS modes available or should the approach be flown with TRK and FPA.
Any references to confirm LOC and GS is a considered a managed or selected mode would be appreciated.
Thanks in advance.
