Which statement best describes Coded Departure Routes (CDR)?

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

Answer: (A)

Coded Departure Routes are preplanned, standardized departure paths that can be issued quickly and shared with pilots, air traffic controllers, and FAA automation systems. The key idea is speed and consistency: the route is already defined and encoded so clearance can be transmitted digitally and automatically fed into the aircraft’s flight management system and ATC tools. This reduces radio chatter, speeds up departures, and helps ensure everyone is following the same, verified path from takeoff to the en route structure. It’s not about weather guidance, taxi paths on the ground, or visual sightseeing routes, which is why those options don’t fit.
