symbol is displayed on the
waterline, and bank angle indica-
tors are not displayed. Because
you are maneuvering in relation

The "X" over BOMBS, indicating
that the master armament switch
on the weapons selector panel is set to SAFE, is removed when the master armament switch is set to
ARM. The DSL A/G aiming reticle consists of two concentric dashed rings around the pipper. The
inner ring has a radius of 25 mils and the outer ring has a radius of 50 mils. Below the outer ring are
two reference marks at 75 and 100 mils (Figure 8).
