When the separation of the fixed cross and the dot shows that a long lead, around 85 to 100 mils, is
being allowed, any small ranging error is magnified by distance and makes long range firing
unprofitable. When only a short lead is indicated, small ranging errors are unimportant. Fire is
effective at maximum range.
When closing in on a target at ranges of less than 600 feet, the diamonds can be ignored altogether.
Effective fire can be made by simply keeping the dot on target.
Both the gyro and fixed sights are seen on a reflector plate. They are focused to infinity by means of
collimator lenses. Parallex has been reduced to a minimum, which prevents a shifting of the target in
relation to the reticle when moving the pilot's line of sight through the gunsight.
The illustration below demonstrates correct and incorrect aiming solutions for a number of likely
engagement scenarions.
Target Pattern. Right and Wrong
Correct – You have exact range now. Fire! Incorrect – Dot is not on target.
