What is the ideal setting for the brilliance control during radar operation?

The ideal setting for the brilliance control during radar operation is to have it barely visible. This setting provides the best contrast on the radar display, allowing the operator to distinguish between targets and the background more effectively. When the brilliance is set too high, the display can become washed out and details can be obscured, making it difficult to interpret the radar data accurately. Conversely, if the display is too dim, critical information may be lost, impairing situational awareness and the ability to navigate safely. Therefore, having a barely visible brilliance setting strikes a balance that enhances the clarity of the radar image, ensuring that operators can monitor their surroundings while avoiding glare and other visual distractions.
