GPS Primary Lost during RNP-AR approach
Hi All
This questions refers to Missed Approach actions in the event of a GPS Primary lost on both sides on A320/330 types during a RNP-AR approach WITHOUT a Nav Accuracy Downgrade.
In this case, can the Missed Approach be flown in Nav mode or will you need to pull Heading to execute the extraction maneuver?
Obviously the actual RNP will degrade without GPS sensor input, but can we rely on the Nav accuracy until the Nav Accuracy Downgrade alert?
