In radar separation, when is the visual separation between an arrival and a departure considered a delay?

• A. If the departure is instructed to hold.
• B. If the arrival is not turning base or nearer.
• C. If the departure climbs above the arrival.
• D. If the arrival uses vertical separation.

Answer: (B)

Visual separation is only relied on as a delaying factor when you don’t yet have a clear, defined path that keeps the two aircraft apart. If the arrival isn’t turning onto the base leg and isn’t getting closer to the runway, you can’t rely on it to establish the needed visual separation with the departing aircraft. In that situation, the departure must be delayed to preserve safe spacing until the arrival rotates onto a path that creates a visible, stable separation or until another separation method can be applied. If the arrival were turning base or getting nearer, the controller could establish the actual separation visually and allow the departure to proceed with little or no delay. The other options involve holding the departure or relying on vertical separation, which are different tools or criteria and don’t define the condition where visual separation itself is considered a delay.
