Additional manual manipulation of the highlight box is provided by the four
corners on the CCD touch pad that, when touched, result in the highlighting of the
corresponding 1L, 1R, 6L, or 6R line select key position.
An enter or line key selection may be performed utilizing any of the following:
• pushing the ENTER key on the onside multifunction keypad
• pushing the Cursor Select Switch on the onside multifunction keypad
• pushing the Cursor Select Switch on the onside CCD
Automatic Highlight Box Positioning
To facilitate data entry during preflight an autotabbing feature has been
implemented to guide the pilot through the data entry process. When data is
entered into a field in which autotabbing has been enabled, the hightlight box
automatically moves to the next appropriate entry field. Autotabbing only
operates when entering a page from a line select key and does not operate when a
function key is used to enter a page. Autotabbing is enabled on the following FMC
pages:
• ROUTE 1/X
• PERF INIT
• TAKEOFF REF
• TAKEOFF REF 1/2
The pilot can still move the highlight box with either the CCD or the CCS to any
active area within a page even if that area is not on the immediate autotabbing
sequence. This action does not disable autotabbing regardless of the position of
the highlight box. As long as a valid entry is made on a field that is in the
autotabbing sequence, autotabbing immediately takes over the highlight box
repositioning again.
If a valid entry is made in a field that is not in the autotabbing sequence, the
highlight does not move and the pilot must move it manually to the next desired
field. Whenever a delete is performed, the pilot must also manually move the
highlight box to the next desired field.
Autotabbing only operates in the display area adjacent to the line selection keys
and does not include the CDU function keys. Autotabbing is discontinued after the
FMS preflight is complete.
