The little thing that you see coming in from the left in the Pilot Attack Sight is the "Pipper" (a white aming dot) and under it the "Horizon Bar" the short white line. If you watch it come into the centre then you will see a pair of white "Range Brackets" appear...This indicates that missiles on both sides are in range and can be fired. Not in the sight picture but attached to the side of the sight body are two "Missile Aquisition Lights"...These come on to tell you that the missile's radar has aquired the target. They will NOT aquire if you have forgotten to arm them early enough and if they don't aquire then you won't get the "Range Brackets".
