is not in the database, the new navaid page comes up. A “clear” action
reverts the selection to the autotuned navaid.
Line 2 CRS This line displays courses for the navaids on Line 1.
The pilot can manually enter the courses via these fields.
It displays “T”, if a tuned VOR is true North-referenced.
[ 3L ] ILS/FREQ This field displays the ILS ident and frequency. It is autotuned, if the ILS
is associated with the departure runway, or if the flight plan shows an
ILS approach selected for the destination. The ILS may also be entered
manually. When the manually-entered ILS differs from the ILS that would be
autotuned,
“RWY-ILS MISMATCH” appears.
[ 4L ] CRS This field displays the course associated with the ILS on Line 3. It
comes up automatically when an ILS is autotuned, or if an ILS has been
manually-tuned via its ident. Otherwise, the course must be entered
manually.
The course may be backbeam (Bxxx), or frontbeam (Fxxx).
[ 3R ] CHAN/MLS The pilot manually tunes an MLS by its ident, or its channel. The system
automatically tunes the associated course and slope.
Note: If an MLS is tuned while an ILS was tuned, the ILS is deselected.

When an ADF1 is selected, these fields display an ADF/BFO prompt. The
flight crew presses the key once to erase the arrow and put the ADF in BFO
mode. A clear action brings the arrow back and cancels BFO.
Note: The autotune function only works for navaids stored in the database.‐
When tuning manually, the operator should use the ident rather than the frequency,‐
unless the navaid is not in the database.
Manually tuned frequencies are displayed in large font.‐
SECONDARY PAGES
Applicable to:
GENERAL
The SEC F-PLN key on the MCDU console allows the flight crew to call up the secondary index
page and the secondary flight plan page. The secondary flight plan is generally for a diversion, for
predictable runway changes for takeoff or landing, or for training.
There are two types of secondary index pages. The type selected depends on the presence of a
secondary flight plan.
