Heads-Up Display Modes 35 - Metaboli

Heads-Up Display Modes 65
When the seeker tracks a target, the HUD shows the following information:
altitude and true airspeed of your aircraft, aircraft datum and bank scale, type of
missile, and quantity. The HUD mode indicator displays ABJ (LMA). Lock onto the
target is evidenced by the movable aiming reticle showing an angular position of
the seeker head, and by the Shoot Cue GH.
You should maneuver the aircraft so that the movable aiming reticle stays close to
the HUD center datum. This eases aiming at the target and prevents the target
from breaking the lock.
If the target leaves the tracking area of the seeker head, or you break the lock by
pressing Tab, or the target is destroyed, the HUD returns to the mode that
immediately preceded the track mode ABJ (LMA).
3.4. Su-25 HUD Modes
The anti-radar missiles Kh-58 and Kh-25
MP are very easy to use; fly the nose of
your plane towards the electromagnetic
source and lock the target pressing the Tab
key. The pipper will then center to the
emission source, the distance to the
target, and the minimun launch distance in
the outer circle. Since these are fire and
forget missiles, once launched you can
look for another emission sources if you
have enough missiles, of course.
The laser-guided missiles Kh25L and Kh-25ML are a bit more complicated to
manage, as they need the pilot to manually designate the target. First, you need
to establish visual contact with the target and begin a gradual descent. The autothrottle
feature can be very useful.
With the nose of your plane pointing at the target, turn on the laser pressing the
0 key. The pipper appears in the HUD, and you will need to move it over the
target. When it is over the target, pressing the Tab key will lock it. The pipper is
now fixed at the selected point and shows us the slant range distance and the
minimum launch distance indicators.
Information provided by the marks at the ring of the pipper:
Dynamic Indicators
• The narrow arc is the slant range distance indicator (moves counter-clockwise).
• The wide arc shows the remaining distance to the minimum launch distance
(moves counter-clockwise).
• The small triangle that you can see at twelve o'clock is a bank indicator.
Static Marks
• Each long line indicates 1000 m of slant range distance to target.
• Each short line indicates 250 m of slant range distance to target.
Once locked, you can still move the pipper. So it’s important to launch the missile
well before we arrive at the minimum distance; we can continue making fine
adjustments after that. Note that the wide arc disappears when we are at the
minimum launch distance.
