CDO Jeppesen Feedback

� Source is very different, depending on State

� Keep procedure names simple ! (coding limited to 6 characters)� Chart Identification: note on the chart (there is no Route Type in ARINC for CDO), do not use CDO in the procedure designation� Create consistency in the name: Continuous Descent operations, Continuous Descent Arrivals, Continuous Descent Approaches…

� Define a minimum set of data which shall go on the chart, if available and depending on the type of CDO.

�Global Database Identification format (Spain uses, for example DC (DescensoContinuo)

� Awareness that speed restrictions and altitude constraints can only be coded at a fix level and not to a segment.

� Recommendation to use ICAO abbreviated procedure description method to support database coding
