locked only if the target in the cursor is within 5 meters of the expected target size, with<br />
the exception of targets larger than 60 meters that can still be locked with the maximum<br />
setting of 60 m. The expected target size and cursor size are adjusted with [RCtrl-]] and<br />
[RCtrl-[].<br />
Along the top and extreme left edge of the display are azimuth and elevation scales,<br />
respectively. The viewing direction of the currently displayed image is indicated by<br />
triangular markers. The upper azimuth scale has graduated markings from -40 to +40<br />
degrees. The elevation scale at the left of the TV display extends from +20 to –90 degrees.<br />
The aircraft pitch is displayed to the right of the view elevation scale.<br />
An aircraft datum similar to the one displayed on the HUD is duplicated at the center of the<br />
TV display. It informs the pilot about the aircraft bank while performing "head-down"<br />
targeting tasks.<br />
The aircraft altitude above ground level (AGL) is indicated by the radio altimeter in the<br />
upper right corner of the display.<br />
KC at the top of the display, to the left of the radio altitude, indicates that the view steering<br />
is under manual control, and no target has yet been locked.<br />
The estimated missile time of flight (TOF) to the target in seconds is displayed in the lower<br />
right corner. After missile launch, this number indicates the time remaining until weapon<br />
impact.<br />
The slant range to the target in kilometers, as measured by the laser rangefinder, is<br />
displayed at the bottom of the display.<br />
Upon spotting the target, the pilot moves the laser cursor over it, and the targeting system attempts<br />
an automatic lock. To aid in target identification, the TV camera field of view (FOV) can be magnified<br />
to 23x (0.73х0.97 degrees) or an intermediate value of 8x. View magnification is controlled with [+]<br />
and [-] keys in three steps.<br />
