FMS GENERAL DESCRIPTION
MCDU 5
DISPLAY SCREEN
The MCDU display screen contains 14
lines, each having 24 characters and is
divided into three functional areas:
−
On top, line 1 is normally used as a
title line, or to display data to which
the pilot does not have access.
−
There are six data fields on each side
of the display, from lines 2 through 13.
They are in six pairs (lines 2-3, 4-5, 6-
7, 8-9, 10-11, 12-13). Each pair of
lines has a label line (the top of the
two lines) and a data line.
The data lines are adjacent to the line select keys, and the label line
is just above the data line.
−
The bottom line (line 14) is the scratchpad line and is used by the
pilot to insert or modify data in the data fields, or to display FMS
messages.
LINE SELECT KEYS
There are six line select keys (LSK) on each side of the display screen,
adjacent to the data lines.
The left keys are identified as [1L] through [6L] and the right keys are
identified as [1R] through [6R].
The line select keys are used:
−
To enter data written in the scratchpad,
−
To access sub-menu, shown by symbol < or >,
−
To activate a specific function identified by a prompt *,
