inside the diamond circle. This procedure reduces over-ranging, prevents over-correction, and most
quickly achieves a firing solution.
When the target aircraft is at right angles - a 90° deflection shot - the wings cannot be used to set
the sight frame, even if the target is banking. On most aircraft, the distance from the cockpit to the
extreme end of the tail is approximately half of the wingspan. Therefore, correct aim can be achieved
by placing the dot on the cockpit with the imaginary circle touching the tail.
Note that the circle is on the extreme end of the tail; not just the assembly.

If neither the wings or fuselage are at right angles, the frame must be made slightly larger than the
aircraft to compensate for the viewing angle. If wings and fuselage are at 45°, an additional 1/6 of
the diameter should be added, or 1/3 of the radius, on each side of the target, ranging on the tip of
the wings and the tip of the tail. This is the maximum allowance. One-tenth of the diameter of the
reticle serves for most purposes.
