When issuing clearance void times at airports not served by control towers, pilots must advise ATC of their intentions no later than ____ minutes after the clearance void time if not airborne.

When airports without a control tower rely on pilot clarity, a clearance void time marks the moment the previous clearance ceases to be valid if you haven’t taken off. If you’re still on the ground and not airborne by that void time, you must advise ATC of your intentions within a half-hour after that moment. This helps ATC manage runway and airspace effectively, re-sequence traffic, and decide whether to assign a new clearance or cancel the previous one. It keeps the control system informed about whether you plan to depart, delay, or discontinue the clearance. If you’re already airborne by the void time, you don’t need to call about intentions at that moment.
