Step 2. Select a Target.<br />
Once you have visually spotted a<br />
target, place it in the field of view<br />
of the HUD by maneuvering your<br />
aircraft and/or Vertical Scan or<br />
Boresight scan cones.<br />
Moving the Scan Cone to the Target<br />
Step 3. Lock onto the Target.<br />
To lock onto the target, press Tab. Failing locking conditions, the Autotrack Cue<br />
flashes at a frequency of 2 Hz. In this case, press Tab until A turns permanent. The<br />
radar/EOS switches to Autotrack mode, as evidenced by the change of<br />
information on the HUD and MFD. If several targets are within the field of view of<br />
the HUD, the equipment tracks the target that has been detected earliest. You<br />
may have to press Tab several times to obtain a lock.<br />
IKTV (HMTD) Helmet Mode<br />
This is also a Close Air submode that, while visually similar to the Boresight<br />
submode, is very different. This submode can be activated by selecting the 5 key.<br />
The Helmet-Mounted Target Designation (HMTD) system frees the pilot from<br />
having to boresight his enemy by slaving the radar and the EOS to the helmetmounted<br />
sight. Once you have acquired the target, the Helmet mode allows you<br />
to keep your eye on the target at all times by turning your head in the direction of<br />
the target’s motion. The real-world system works by using a pair of head position<br />
sensors on the cockpit panel, on each side of the HUD.<br />
The radar (the EOS) locks onto the target in an area limited by the 2.5∞ scan cone.<br />
The pilot should keep the cone within the limits of the radar/EOS field of search.<br />
That means that you cannot use your helmet-mounted sight to acquire and lock<br />
onto targets beyond the gimbal limits of the radar antenna or the IRST sensor ball.<br />
Acquiring a Target<br />
Use the following procedure to lock a target with the IKTV (HMTD) mode:<br />
Step 1. Switch to Helmet Mode.<br />
Press the 5 key. The HUD submode indicator displays the notation IKTV<br />
(HMTD) (pronounced "shlem," denotes "Helmet" in Russian) on the lower-right<br />
corner of the HUD. The targeting circle appears in front of you and follows the<br />
movement of your head.
