Which designation is not associated with uncontrolled taxiways without clearance from ATC?

The designation associated with uncontrolled taxiways without clearance from Air Traffic Control (ATC) is referred to as "Delta Romero" (DR) or "Delta Sierra" (DS). These designations are used specifically to navigate and understand procedures on uncontrolled taxiways where pilots and vehicle operators must maintain vigilance and situational awareness due to the absence of ATC control.

Juliet (J) is typically used to designate a specific type of taxiway or a controlled routing, rather than indicating an uncontrolled area. Therefore, it is not associated with uncontrolled taxiways, making it the correct choice in this scenario. Understanding the distinctions between these designations is vital for safe operations on airside logistics, as they impact how pilots and vehicles communicate and navigate within airport parameters.
