Milestones and alerts

Key to the Airport CDM process is the generation of milestones and alerts.

Each flight must pass specific milestones so that everyone involved knows the status of the flight/aircraft at any given time. A designated partner is notified by Airport CDM alerts (as a result of milestone generation) of any amendments required as a result of changes to the process.

The alerts are split into three categories – red, orange and yellow.

  • Red – A red alert means the Airport CDM process for this flight is halted and urgent action is required.
  • Orange – An orange alert means the process is not being halted, but may well be at a later point in time. Clarification is needed in any case.
  • Yellow – A yellow alert is for informational purposes. The process is at no time halted, but clarification is needed.
