1.3.1. Data Command Switch (DCS) & scratchpad
The DCS is a four way momentary switch situated on the bottom row of the ICP, next
to the DRIFT C/O
– WARN RESET switch.
The LEFT position is labelled RTN and allows exit from the current DED page or
return to the CNI DED page.
The top position is labelled with an up arrow and cycles the DED cursors to editable
functions (scratchpad) moving upward.
The bottom position is labelled with a down arrow and cycles the DED cursor to editable functions
downward.
The right position is labelled SEQ and is used to enter extra subpages or options of the current priority
function.
1.3.2. ENTR and RCL button
Those two buttons have no priority functions and only serve to confirm or cancel the entered data.
After entering data in the scratchpad the ENTR button must be depressed to submit the changed data.
The system checks if the data is valid and if it is enters it, then moves on to the next editable area. If
the data is invalid the inputted data will flash and the pilot will have to correct any errors.
The RCL (Recall) will clear the last data entry. If pushed twice in succession the entire scratchpad will
be cleared.
1.3.3. DED scratchpad
The scratchpad is an editable area receiving alphanumeric values
from the ICP keys. The scratchpad area is displayed in the DED
between two asterisks.
The scratchpad area on the left picture is around the Laser Start
Time, which is initially set to 20 seconds before weapon impact.
Any press on the ICP buttons will change the numerical value. For
instance, if we press 1 then 6 the laser time will change to 16
seconds when the ENTR key is pressed and the scratchpad is
moved automatically to the next area (if the data is valid) or
manually by moving the DCS switch up or down.
To return to the default DED (CNI) page, move the DCS to the RTN
(left) position.
Anytime the scratchpad is not active a press of a priority button will
enter the relevant subpage.
Each of them is covered later in this section.
1.3.4. CNI page
The Communication, Navigation and Identification DED page (CNI)
is the default page for the DED.
It displays information about the current radio settings for both
COM1 & COM2 radios, the active steerpoint, current time, IFF mode
& codes and active TACAN or DME when A/A TACAN is active.
The CNI page is only accessible when the CNI switch on the AUX COMMS panel is set to UFC. When
placed in BACKUP the UFC is inoperative and all backup systems are active and controlled from the
side consoles.
Note the up and down arrow on the steerpoint on the CNI page. This shows that the current steerpoint
can be incremented or decremented with the PREV/NEXT button of the ICP (the rocker switch located
left of the DCS) without leaving the CNI page. As with the scratchpad, the arrows can be cycled
through the fields that can be edited by moving the DCS up and down.
