Leading Particulars
Table 9-4
The CD-81O Control Display Unit (CDU) is the pilot interface with the
FMS. The CRT displays relative flight information to the pilot. The
pilot enters alphanumeric data into the system via the full alphanumeric
keyboard. This data appears in the scratchpad to be line selected to the
appropriate position on the CRT display. The CDU function controls are
described in the following paragraphs:
9. B. (1) CRT Display - A color CRT is used to display data on the CDU. The
displays consist of 9
lines, each line containing 24 characters.
The first 1 ine is a title 1
ine and the ninth 1ine is the scratchpad.
The intermediate lines and scratchpad are available for data display
and entry.
(2) Photosensors and Brightness Control - CRT brightness control is
provided in order to maintain readability under dim light as well as
direct sunlight. This is accomplished in two ways:
(a) Manually by the brightness knob - The brightness knob is
provided to manually vary the intensity of the CRT display for
a given ambient light level.
(b) Automatically by the photosensors - The photosensors sense the
ambient light and adjust the CRT brightness automatically to
maintain the relative brightness set by the brightness knob.
