When a clearance is requested and not issued, the delay occurs due to which condition?

• A. An EDC expires
• B. When SYD is available
• C. When available (coordination, if any, is done and traffic allows)
• D. By the end of the scenario

Answer: (C)

Clearance issuance happens only when everything needed is ready: the clearance itself must be available, any necessary coordination completed, and the traffic situation allows it to be safely given. If any of those parts aren’t in place, the clearance remains pending, creating the delay. That’s why the best condition is when clearance is available, coordination is done if required, and traffic permits issuance.

Why the other ideas aren’t the right gating condition: waiting for an EDC to expire is a timing boundary on a previously allocated window, not the fundamental gating factor for issuing a new clearance. Waiting for a specific location’s availability (like SYD) isn’t the general rule for clearance release, and saying it will happen by the end of the scenario just describes time passing rather than the readiness to issue the clearance.
