If the shooter has a radar lock on, then the problem gets much simpler. Now, the LCOSS is getting a range input that it can use to correctly compute the lead angle and gravity drop components. Depending on the sight type, the other assumptions (constant range, no overtake, etc) may still apply. The next two pictures show typical LCOSS reticle displays. The Janes USAF reticle includes the range analog bar. The Falcon 4 picture shows the reticle display for a no radar lock situation. In this example, the reticle indicates a range of 1500 feet. The Falcon 4 LCOSS reticle with a radar lock looks exactly the same…however the reticle will now represent a firing solution for the exact target range.
Determining Target Plane of Motion
The visual references for getting into the target’s plane of motion are the same as they were for the fixed sight. In addition, with the disturbed reticle LCOSS, you may use the displaced pipper or funnel axis as an indication of your plane of motion. The line from the gun cross to the pipper, or the axis of the funnel, represents your flight path. Use this as a guide in bank control to match the target’s flight path.
