RNP accuracy provided by the FMGES with GPS Primary
• NAV mode, AP ON :En route 1 NM / Terminal area 0.5 NM / Approach 0.3 NM• NAV mode, AP OFF and FD ON :En route 1 NM / Terminal area 0.51 NM / Approach 0.3 NM• HDG mode, AP OFF and FD OFF:En route 1,1 NM / Terminal area 0.51 NM / Approach Not authorized
Requirements before using NAV mode after take-off
FMGS runway updating must be checked
RNP accuracy provided by the FMGES without GPS Primary
Navigation accuracy is function of NAVAID infrastructure and elapsed time since the last radio update
Take-off from airports where the difference between the local coordinate system and WGS 84 is not negligible
• Airborne, incorrect NAV guidance may occur• GPS must be deselected until a safe altitude is reached
NAV-FPA/Final APP modes for NPA (VOR or NDB), Requirements on Navaid availability
• NPA may be performed in NAV or FINAL APP mode provided AP or FD is used and- GPS PRIMARY: NAVAID/Aircraft radio equipment can be inoperative- Without GPS PRIMARY: . Accuracy is High and . NAVAID serviceable tuned and monitored during the approach
