RNP accuracy with GPS Primary: en route with AP on, AP off and FD on, both ap and FD off?
1nm, 1nm, 1.1nm
RNP accuracy with GPS Primary: in the terminal area with AP on, AP off and FD on, both ap and FD off?
0.5nm, 0.51nm, 0.51nm
RNP accuracy with GPS Primary: in approach with AP on, AP off and FD on, both ap and FD off?
0.3nm, 0.3nm, 0.3nm
If GPS Primary Lost is displayed on the ND and MCDU, what do you look for to know that navigation accuracy remains sufficient for RNP operations?
On the MCDU, check that High Accuracy is displayed in the Prog Page
Can NAV mode on an RNAV (RNP) approach be performed if GPS in not available?
Yes, it may be performed, provided:
- High Accuracy is displayed on the Prog Page of the MCDU
- Verify position with radio navaid coverage to identify which FMGC has the correct position
- Operational approval is obtained
- RNAV RNP degradation procedure must have been briefed during the Approach Briefing
Can NAV mode be used if GPS Primary is lost with an approach based on Radio Navaids?
Yes. Use NAV Mode while using the reference Navaid and the corresponding radio equipment on the aircraft as a reference
Can we use NAV Mode when GPS Primary is available but the reference Navaid is unserviceable or airborne radio equipment is inoperative?
Yes. If airborne radio equipment is inoperative, operational approval is required
What are examples of NAV Mode for approaches?
NAV, APP NAV, FINAL APP
