Conditions for Employing the AIM-7
Because of the stringent lead requirements for employing the AIM-7, the fighter must be in
the proper position to take a valid shot. The ASE circle and the AIM dot are useful tools to
achieve proper lead. However, it is target aspect that determines the correct conditions.
Accurate target aspect analysis is the decisive factor in employing the AIM-7 Sparrow.
The Sparrow has a greater maximum range against a target with low TA than one with high TA.
The lower TA means higher ROC and thus higher Pk. For the correct ranges and lead angle off
required for different target aspects, refer to the following chart:

Lead Angle & Dot Relationship
Once the correct lead angle off is established, the dot should be located within the ASE
circle. To allow for some error in steering, the ASE circle will accommodate lead AO within +
3 of the proper lead AO. Since the dot is 6 times more sensitive, this implies that the ASE circle
+ 18. Also recall that the dot is aircraft stabilized, so it will indicate to the aircrew
will be
which attitude position the nose should be in to correctly fire the missile. It is that the "Dot" is
an AO dot prior to lead range-meaning it tells the aircrew where to turn for collision-and at lead
range it becomes a lead computing "Steer to Dot" in order to put the aircraft in firing parameters.
