During an operation, what should you do if you are unsure about runway clearance?

• A. Proceed slowly and hope for the best.
• B. Continue without confirmation if time is short.
• C. Consult ATC updates and obtain clearance before moving.
• D. Ask a ground crew member.

Answer: (C)

The essential idea is: never move on or across a runway without explicit clearance from ATC. Runway clearance is controlled by air traffic control, and any decision to enter, cross, or operate on a runway must come from them to ensure safe separation from other aircraft and vehicles.

If you’re unsure about runway status, you should check for ATC updates and obtain clearance before moving. This ensures you have the latest information about active runways, any construction or closures, and the positions of other aircraft or vehicles. Relying on assumptions or time pressures can lead to a dangerous runway incursion, which is what this question aims to prevent.

Why the other options aren’t appropriate: proceeding slowly and hoping for the best ignores the need for authoritative confirmation and increases risk. continuing without confirmation if time is short prioritizes speed over safety and violates procedures. asking a ground crew member is not sufficient because they do not have the authority to issue or revoke runway clearance; ATC is the correct source for that clearance and updates.
