Figure 62: VISUAL GROUND mode
• The display scale is provided in the upper left.
• Rmax and Rmin tick-marks are displayed on the range scale.
• Chosen "ОПТ ЗЕМЛЯ" (VISUAL GROUND) mode is displayed in the lower left corner of the
HUD.
• Dive (pitch) angle is displayed at the center-right of the HUD.
• Moving aiming pipper indicates the computed point of weapon impact.
Hi-drag weapons such as retarded bombs and cluster sub-munitions dispensed from containers have
a low drop trajectory which may cause the aiming pipper to remain below the lower limit of the HUD
even in a diving attack. In this case it’s better to use the continuously computed release point
(CCRP) bombing mode. This mode is described in detail in the "Weapon usage" section.
Reticle
The fixed reticle is not a combat mode, but rather a calibrated image that can be displayed on the
HUD by pressing the [8] key. The fighter WCS remains in the same mode as before [8] was
pressed, but the HUD indications are replaced by the fixed reticle.
The reticle is also a backup instrument for aiming in case of WCS failure or damage.
