A320 FM Position
The wording on the FCOM keeps me confused.
What is the aircraft using for present position
at all times when gps primary:
actual position? (gps)
or
mix GPIRS? which is obviously drifting.
What I'm thinking is why would the a/c use a IRU drifting value
when it can use gps, then if gps pos is drifting from the 3 mix GPIRS's its can assume IRS pos.
cheers guys. gps
