CHAMAN
Definition
A specific procedure created [...] to improve the accuracy of the Network Operations data and to overcome the problems associated with slot compliance during periods of adverse operating conditions at aerodromes. This procedure allows greater flexibility to the FMP/TWR giving them the freedom to manage the departure order based on what they can achieve, taking into account local conditions.
Definition Source
EUROCONTROL, NM Glossary (2014)
Note
CHAMAN is currently only available at specific aerodromes. Each aerodrome qualifying for the procedure must have agreed with the CFMU a detailed plan and instituted CDM procedures with which all parties concerned (AOs, Airports, ATCs, Handling Agents etc.,) have agreed to comply. This process is managed by the CFMU and should be used as a last resort, when all other methods have been exhausted. (same source)
