As the VOR associated data and pointers are displayed, both receivers consider the VOR signal as valid. On the second line, the VOR identifier appears, here “Bravo Tango”.

You can also see the STD indication on the PFD in cyan and yellow boxed. Notice also the selected altitude which has changed to a flight level indication, FL130. Let’s assume we have performed the same setting on the standby altimeter. NAVIGATION MENU Normal operation (B) 29/43 As the VOR receiver 2 receives now a valid signal from the VOR MEL, the associated pointer and data are displayed on the ND. As MEL VOR is not equipped with a DME, the DME indication is replaced by green dashes. NAVIGATION MENU Normal operation (B) 30/43 The indication “” NAV ACCUR UPGRAD” has appeared at the bottom of the ND and in the MCDU scratchpad meaning that the navigation accuracy level has automatically switched from LOW to HIGH. We will see now how to make a navigation accuracy check. NAVIGATION MENU Normal operation (B) 31/43 The objective of the navigation accuracy check is to compare the raw data from the tuned nav aids with the corresponding FM computed data. The SOP recommends to make it periodically in cruise, prior to initiating the descent and when entering a terminal approach area. • If your aircraft is equipped with GPS primary, no accuracy check is required as long as GPS primary is available. The GPS mode can be checked on the PROG page. NAVIGATION MENU Normal operation (B) 32/43 If the GPS is no longer primary, the message “GPS PRIMARY LOST” is displayed on the ND and in the MCDU scratchpad. Notice that the navigation accuracy level stays at HIGH. Nevertheless, the navigation accuracy has to be verified. The SOP recommends in such a case to perform the comparison in a hourly base. NAVIGATION MENU Normal operation (B) 33/43 This check has to be performed whenever the following cases occur: - IRS only navigation, - The PROG page displays LOW accuracy, - “NAV ACCUR DOWNGRAD” message appears on the MCDU and on the ND. NAVIGATION MENU Normal operation (B) 34/43 To perform this check, you have to use the selected nav aids and display them on the ND. We have set the ND range to 80. The VOR “Sierra Papa Romeo” has been manually tuned on receiver 1 and the VOR “Papa Alpha Sierra” on receiver 2. Note that the VOR “Papa Alpha Sierra” is the next “TO” waypoint of the flight plan. NAVIGATION MENU Normal operation (B) 35/43 There are two ways to do this check. The first method is to compare the “TO” waypoint distance and bearing which is FM computed data with the corresponding nav aid DME distance and bearing.

The distances shown on the ND and on the PROG page can be compared. Compare these two distances DME distance Computed BRG / DIST NAVIGATION MENU Normal operation (B) 42/43 The last method consists in checking that the raw data needle passes through the blue FMGS generated symbol for the VOR/DME, and that the position of this symbol corresponds to the DME distance. NAVIGATION MENU Normal operation (B) 43/43 Whatever method is used, if the error is less than 3 NM, the check is positive and the FM position is reliable. The SOP recommends to use the ND in ARC or NAV mode and managed lateral guidance. If the error is greater than 3 NM, you can consider that the FM position is not reliable. In such a case, the SOP recommends to use raw data for navigation and to monitor it.
