Which is the correct phraseology to have a clearance relayed through a non ATC facility?

• A. ATC CLEARS
• B. CLEARANCE THROUGH NON-ATC FACILITY
• C. NON-ATC CLEARANCE RECOMMENDED
• D. ATC AUTHORIZES CLEARANCE

Answer: (A)

The main idea is that the clearance authority rests with air traffic control, even when the message is relayed through a non-ATC facility. Using the phrase “ATC clears” makes clear that ATC authorized the clearance, and that the intermediate, non-ATC facility is only relaying it, not granting permission. This preserves proper, unambiguous communication and avoids suggesting that the non-ATC facility has the authority to issue the clearance. The other phrasings either imply non-ATC authority or are not standard ways to convey a clearance via a relay.
