What does Coded Departure Routes (CDR) refer to?

• A. A weather advisory route used for dynamic wind planning.
• B. A preplanned route of flight that can be rapidly issued, coordinated, and communicated to pilots, controllers, and FFA automation systems.
• C. A ground route for emergency only.
• D. A visual route for sightseeing

Answer: (B)

Coded Departure Routes are a standardized, preplanned path from takeoff to the en-route phase that can be rapidly issued and loaded into both the aircraft’s navigation system and air traffic control automation. Instead of spelling out every turn and fix verbally, the controller assigns a coded route that the pilot can select or the flight management system can execute. This speeds up clearances, reduces radio chatter, and improves coordination among pilots, controllers, and automation—especially at busy or weather-affected airports. The other options describe routes for weather planning, emergency-only ground routes, or visual sightseeing, none of which match the purpose of a coded departure route.
