During night CARQUAL, control uses a single frequency to control all aircraft in the CARQUAL pattern.

Using a single frequency for all aircraft in the CARQUAL pattern ensures centralized and synchronized communication. When every pilot tunes to one common channel, the controller’s instructions—such as where to enter, how to sequence, spacing, and turns—are heard by everyone at the same time. This provides consistent guidance and reduces the risk of conflicting or missed transmissions, which is especially important at night when visual cues are limited and pilots rely more on radio instructions. The approach prioritizes safety and coordination over having separate channels, and it isn’t determined by weather—it's about keeping the entire pattern under one clear line of communication so all aircraft respond to the same directives.
