Logged into a navigation provider and pulled CDRs from KORD…KTPA. Here’s what it spit out and here is the advisory data that goes with it:
Coded Departure Route (CDR) Procedures
- CDRs are meant to reduce workload between various ATC facilities. They are also meant to reduce frequency congestion by minimizing read-back time between ATC and pilots when alternate route clearances are needed due to weather conditions.
- Each CDR is assigned an eight-character code to represent a predefined route between specific city pairs.
- A city pair may have more than one CDR.
- There are roughly 15,000 CDRs in effect at the present time.
- There is also a button on the Main Page which will allow you to enter city pairs and check for any existing CDRs.
Information on CDR Routes
- Request a full route clearance if there is any doubt of understanding the abbreviated clearance.
- Tell the controller you are unable to accept a CDR if the aircraft is not properly equipped or capable of flying the issued CDR. For example, some CDRs may require HF communication or Area Navigation capability.
- You must have on board the aircraft all current CDRs for the specific city pair you are expecting to fly.
- Put the phrase ‘CDR CAPABLE’ in the remarks section of your flight plan. You may still receive a reroute if ATC deems it necessary but no abbreviated clearance” will be issued.
- Some CDRs add hundreds of miles to your expected/normal route between city pairs. Special consideration MUST be given to fuel requirements and IFR fuel reserves.
- The flight crew is responsible for maintaining a current database of CDRs
