![]() Explanation of how the slots work in N-OCSlots are separate objects in the system. This means that they are completely independent and can exist without the need to first create a schedule. However, slots can of course be linked to an existing schedule. This can be considered a kind of a reference, stating that a slot belongs to a specific schedule. A slot can belong to no schedules at all, or one or two schedules, depending on how it is created. UnlinkedIf the slot is created in the slot wizard it will belong to zero schedules. This is referred to as 'unlinked'. One ScheduleIf it is a Departure or an Arrival slot, then it belongs to one schedule. Two SchedulesIf it is a so called 'Turnaround' slot, then it belongs to two schedules. ![]() Here is an example of how a slot is displayed in the Schedule Gantt. The semicircular yellow display on the left side of the leg indicates that the schedule is linked with a slot for the coordinated airport CPH. On the right side, there is no such display, indicating that no slot for AAC as required. (as it is not a coordinated airport). Schedules without slotsSchedules can also exist in N-OC without a slot in the system, even if the schedule has coordinated stations. (If checked in the slot wizard it would not display the slot at all - more on this later on). This is rectified by generating slots required (based on the loaded schedule). The system will run a check for all coordinated stations, and if any schedules are missing slots , the Slot Wizard will create them. We will look at this further on. In this example, the schedule is missing a slot for the coordinated airport CPH, but there is a slot for the same schedule for the coordinated airport EDI. ![]() Slot WizardThe Slot Wizard is located on the icon bar at the the top of the Schedule Gantt. ![]() The Slot Wizard handles all slot tracking and communication for sending airport slot clearance messages such as: SCR/SMA, as well as receiving responses from the Slot Coordinators. To that end, it also tracks such things as slot statuses (based on the responses received and requests made), and Historical slot tracking. SCR Schedules Clearance Request is used for Coordinated Airports (Level 3) - see below SMA Schedule Movement Advice is used for requests at Schedules Facilitated Airports (Level 2) - see below The user can also access the Slot Wizard by right clicking on a flight leg or legs (Single or multi slot icon) - as shown below: Single mode (one flight leg): ![]() Multi Mode (Multiple flight legs selected: ![]() Slot Levels
