Good evening,
Could anyone explain me how RNAV works?
Does it need GPS/GNSS?
Well, commercial planes like Airbus or Boeing use GPIRS - GPS primary to find there position. The FMGS' database has got each and every coordinate.
So what makes the difference between a simple GPS navigation and a RNAV navigation on commercial airlines?
Again, do we need GPS?
Thanks a lot,
TBF
