When should you issue a 'continue' instruction at a hold short?

• A. When it is safe to cross or proceed as cleared and traffic is clear of conflicts.
• B. As soon as a pilot requests it.
• C. When the weather improves.
• D. Only after runway is completely empty.

Answer: (A)

The main idea is that a continue clearance is given to authorize someone on the hold short line to proceed across or onto the runway when there are no conflicts. You issue it only after you’ve confirmed the area is clear of conflicting traffic and it’s safe to proceed as cleared. It isn’t something granted just because a pilot asks for it, nor is it tied to weather changes or waiting for the runway to be completely empty—the decision is based on current traffic and the absence of conflicts.
