On the PFD, you can check the ILS identifier, “Oscar Lima Echo”
in this case, the frequency and the course. The course is also
indicated on the ND.
The check and the selection of the nav aids are now complete.
We will carry on with the settings of the altimeters.

STD appears on the EFIS control panel. 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

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.

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.
