Pilots want ways to mitigate bad weather. The Coded Departure Route (CDR) is one of the least-known such tools in GA, although its been available since 2007. The AIM tells us, CDRs provide air traffic control a rapid means to reroute departing aircraft when the filed route is constrained by either weather or congestion. So, if youd rather not wait, a CDR might be for you.
Coded Departure Routes (CDRs) are FAA-approved, pre-planned alternate flight paths designed to help pilots rapidly reroute around adverse weather or air traffic congestion.
Available to general aviation since 2007, CDRs offer significantly more route options than SIDs and are part of the Severe Weather Avoidance Program (SWAP).
Pilots can find and file specific CDRs using FAA online resources or flight planning tools, though manual entry of fixes into navigators is often required due to a lack of native support in many GA systems.
