Purpose of CDRs “Conditional Routes” (CDRs) complement the permanent ATS route network. The purpose of CDRs is to allow flights to be planned on and to use ATS routes, or portions thereof, that are not always available. CDRs are established: -through any potential areas of temporary segregation identified under the generic term “AMC-Manageable Areas” (TRAs, TSAs or R or D Areas), with CDR opening/closure resulting from associated military activities and/or -to address specific ATC conditions (e.g. traffic restrictions or ATC sectorisation compatibility), with CDR opening/closure resulting from purely civil needs. The conditions for the use of CDRs will be daily published in the national “Airspace Use Plans” (AUPs) and the “Conditional Route Availability Message” (CRAM). Categories of CDRs CDRs are divided into three different categories according to their foreseen availability and their flight planning potential. A CDR can be established in one or more of the three following categories:
1. Category One (CDR 1) -Permanently Plannable CDR -. Category One CDRs are CDRs expected to be available for most of the time. . Flights will be planned on Category One CDRs in the same way as planned for all permanent ATS routes. . Any re-routing around associated TRAs/TSAs will be made on ATC instructions only. . For the calculation of fuel consumption, alternate routes are published in the “Remarks” column. Depicted on maps as follows : UR 80 (CDR 1)
2. Category Two (CDR 2) -Non-Permanently Plannable CDR -. Category Two CDRs are part of pre-defined routing scenarios which respond to specific capacity imbalances. . Flights will be planned on Category Two CDRs only in accordance with conditions daily published in the CRAM. Depicted on maps as follows : UA 20 (CDR 2)
3. Category Three (CDR 3) -Not Plannable CDR -. Category Three CDRs are published as CDRs usable on ATC instructions only. . Flights will be re-routed on Category Three CDRs on ATC instructions as short notice routing proposals. Depicted on maps as follows : UG 100 (CDR 3)
