Back To Page 17 Director Sight Snap Shot Let’s dispense with the rocket science, and just say that the director sight is designed for a tracking solution. Its reliance on a radar or IR/laser lock on and predictable target behavior all conspire to make snap shots difficult. Remember, the pipper is not an indication of bullet […]

Back To Page 16 Director Sight Tracking Shot Determining Target Range Not a biggie!! We already know that the director system relies on a radar or IR/laser lock on. Accurate ranging is a given in this sight system. The next two figures show how range is displayed in the Flanker 2 and Janes F/A-18 sims. Both use a […]

Back To Page 15 The Director Sight and How to Use It Well…if that is the case, then I had better tell you what those similarities are…right?? OK!! Fair enough!! The most obvious similarity is that the director aiming symbol is displaced away from the gun line. The next similarity is that the director system uses a […]

Back To Page 10 So much for the description of the reticle. Now let’s talk about this term ‘disturbed.’ What is this word referring to? Let’s go back to where we were talking about gyroscopes. We said that a gyroscope would react if a force was applied to it. This reaction (precession) is the gyro being ‘disturbed’ from its […]

Back To Page 14 Disturbed Reticle Snap Shot The disturbed reticle LCOSS can be used for a snap shot attack, but the technique is a bit more complicated than what it was for the fixed sight. In the discussion of the fixed sight, we advocated a one G technique for the snap shot. You can do […]

Back To Page 13 The problem of getting into the target’s plane of motion uncovers another one of those ‘great truths’ of A2A gun employment. Here it is: Do not try to ‘fly’ the pipper (or funnel) to the target. Instead, use traditional BFM to get the target positioned in the approximate center of the HUD […]

Back To Page 12 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 […]

Back To Page 11 If the pilot pushes the rudder while maintaining one G, the nose will yaw in the direction of the rudder application. The reticle will move opposite this movement away from the gun line position. Right rudder…the reticle moves left, and vice versa. In this manner, we see that reticle movement is strictly […]

Back To Page 9 The Disturbed Reticle Sight and How to Use It I guess the place to start is to explain what ‘disturbed reticle’ means! Let’s take the ‘reticle’ part first. The reticle (or reticule, as some texts spell it) is the name of the circle that many sight images look like. In the center […]

Back To Page 8 And now the foot-stomper. This is a one G technique. You want to get the gun line in the target plane of motion and then hold it there. As the target approaches the open fire point, you want to make sure you are at one G. Why? To concentrate your bullet stream. You are literally ‘strafing’ […]

Back To Page 7 Determining Target Plane Of Motion Our next objective is to get our gun line into the target’s plane of motion. The gun line reference, however, is in the HUD. The target, when it is in the ‘window’ is no where near the HUD. So, how do we get into the target’s plane of […]

Back To Page 6 We place the gun line in front of the target and vary our G to allow the target to move towards the approximate lead point. One technique is to start out with a little more lead than necessary…then relax G slightly to move the target ‘forward’ towards the gun line. As the […]
