Paris CDG: Protecting Situational Awareness in a Bilingual ATC Environment

Six briefing priorities

Brief the language threat

Acknowledge that some surrounding traffic calls may not be intelligible.

Prioritise your clearance

Both pilots listen actively whenever your callsign could be involved.

Point to the path

Use the chart, airport moving map and agreed taxi route to maintain a shared picture.

Read back doubt, not confidence

Ask for repetition or clarification whenever wording, runway or routing is uncertain.

Protect heads-up time

Avoid non-essential tasks during complex taxi, vectoring and runway operations.

Update the threat picture

Revise the brief when runway, taxi route, frequency or weather changes.

Language is a threat to manage, not a complaint

English is available for international aviation communication, while local-language use may also occur in some environments. The safety issue is not the language itself; it is the possibility that a crew cannot build context from every exchange around them.

Do not assume that overhearing traffic provides separation or clearance authority. Use it only as supporting awareness.

CDG rewards deliberate surface discipline

Complex layouts, multiple runways, conditional clearances and route amendments can compress workload. Before taxi, identify hot spots, runway crossings, holding points and any place where a wrong turn would be hard to recover.

During taxi, one pilot should remain heads-up while the other confirms the route and manages supporting tasks under the operator’s procedure.

Recover early from uncertainty

If a clearance seems inconsistent with the chart or expected traffic, stop the mental guessing. State the ambiguity clearly and request confirmation.

When safe and necessary on the ground, slowing or stopping before a critical point is usually better than continuing with an incomplete shared picture.
