In A-CDM it is important to allow A-CDM Partners to set the value of some milestones when necessary. The classical example is to allow the Aircraft Operator or the Ground Handler to set the Target Off-Block Time (TOBT) that indicates what is the target time for the aircraft to be ready for off-block. Setting the TOBT value is possible at many stages during the A-CDM process, as early as Milestone 2 (EOBT-2hr) up to and including Milestone 11 (Boarding starts).\n\r The Business Logic may involve validations such as: not accepting values in the past; not accepting a new value too close the existing one (there is a minimum change involved); Limiting the number of changes after TSAT has been issued."

This is done in accordance with the operations involving Target Off-Block Time that take place between A-CDM Milestones 2 and 11 (derived from: Airport CDM Implementation Manual v4)\r\n[IER2] To allow the competent authority to set the value of the Target Off-Block Time for a given aircraft in specific circumstances. In other words, under adverse conditions or special circumstances this service allows the competent authorities to set the Target Off-Block Time value of the flight.
