perature get below –20˚C the CDU will turn
ON but the LCD display will delay indications
by a power-up timer. During this time the
CDU will monitor its internal temperature.
With extreme unit temperatures of –30˚C and
colder, this timer can take as much as 10 min-
utes to illuminate the display.
The CDU has the following controls and dis-
plays:
BRIGHT/DIM Button
This button provides secondary control of the
display intensity. The PILOT DISPLAYS rheo-
stat on the overhead panel provides primary
control.
Title Line
This line displays the page title and page num-
ber. The page number is formatted as the cur-
rent page number followed by a slash and the
total number of pages.
Line Select Keys
These keys activate functions displayed on the
CDU adjacent to the line select key. The line
functions depend on which page is displayed.
Label/Data Line Pairs
Two display lines are associated with each line
select key. The top line is normally a label for
the information that is shown on the data line
Displayed on the second (bottom) line.
The data line can display large or small char-
acters. When the system has entered informa-
tion the text will be in a smaller size. When the
operator has entered information the text will
be larger in size.
Scratchpad Line
The scratchpad line displays data entered by
the alphanumeric keys, or data selected for
transfer by a line key. Brackets identify this
line and it is the only place where the operator
can input information from the keypad. Once
input data is displayed on this line it should be
verified before transferring to a selected field.
Should an entry occur that is not compatible
with the selected item, the scratchpad will mo-
mentarily display a message to indicate details
about the error. This message will time out and
the previously entered information will return,
so that it may be corrected.
Message Line
A single message line is reserved along the
bottom line of every page to annunciate con-
ditions requiring operator attention or simply
to provide information. If more than one mes-
sage is active the message key (MSG) may be
used to display additional messages as dis-
cussed later in this section.
Alphanumeric Keys
These keys enter data in the scratchpad line of
the display. The data entry keys are as follows;
the 0–9 number keys; the A-Z letter keys; the
period key; the +/– (plus/minus) key; the SP
(space) key; the / (slash) key; and the
CLR/DEL (clear/delete) key. The compass
cardinal headings of N, E, S, and W are high-
lighted with a white box to ease entry of items
requiring direction inputs. Care must be exer-
cised not to confuse the letter “O” with the
number “0” on the keypad.
IDX Key
The IDx (index) key controls display of items
that do not have a dedicated function key. It
also is a central location for setup and config-
uration pages for FMS and GPS operations.
