Is autopilot or FD necessary for PBN RNP APCH (LNAV)
Hi,
Looking for information regarding PBN. Have to figure-out is autopilot or flight-director is necessary on board to get operational approval for RNP APCH (LNAV). In AMC 20-27 You can find some not very clear statements, from which can be understood, that AFCS is necessary. Thanks in advance!
