BOTTOM ROW is displayed as usual with declutter and swap buttons (#11 & #15) and the direct
access buttons between them.
HSD cursor
When the FCR and the HSD are both displayed and the FCR is SOI the HSD displays the ghost radar
cursors moving within the radar scan zone depicted on the HSD.
When the HSD is made SOI the ghost radar cursor is replaced with the HSD cursor which is shown as
a cross. Any subsequent cursor movement will then move the HSD cursor and not the radar cursor.
The HSD cursor can be used to select new steerpoints of interest and toggle on/off specific threat
rings on PPTs displayed on the HSD. TMS up over a HSD steerpoint makes that steerpoint the new
steerpoint of interest, TMS down on a PPT will deactivate the associated threat ring. This cursor has
its own bullseye reading on the right side of the HSD, between OSBs #9 and #10.
Cursor bumping
To change the range of the HSD you can use OSBs#19 & #20 in DCPL mode or change the FCR
range in CPL mode.
There is a third way to change the HSD range (which is also valid for the FCR) that is called cursor
bumping. It is done by moving the cursor towards the upper or lower edge of the display. When the
cursor gets close the range will automatically change up or down accordingly. This is done mainly on
the FCR because most of the time the FCR is SOI, but it also works on the HSD when it is SOI.
If the HSD is in CPL mode the first hit on any top or bottom edge will switch the HSD to DCPL mode
and subsequent hits will change the range.
Bullseye symbols
There are many different bullseye symbols on the HSD page.
You can find bearing and range information from Bullseye for your ownship, the ghost radar cursor,
and the HSD cursor when it is displayed.
Ownship bullseye information is always displayed in the bottom left corner of the HSD. It is the same
information that is displayed in the bottom left
corner of the HUD when Bullseye is mode selected
in the UFC (LIST-MISC-BULL page). If Bullseye is
not mode selected this symbol is replaced by a mini
flight director relative to the active steerpoint.
Ownship Bullseye is coloured cyan with the bearing
below the circle and the distance in the circle.
Distance is limited to 2 digits, so if Bullseye is
further away than 99 Nm the circle is empty.
Ghost radar cursor Bullseye information is
displayed in white on the left side of the MFD. The
first number is bearing in degrees and the second
number is distance in Nm.
HSD cursor Bullseye readout if displayed (HSD
SOI) is on the right side of the screen and has the
same structure as the ghost radar cursor
information, i.e.: bearing then distance.
