Visits
A visit is continuous interval when an aircraft is at a specific track and is available for maintenance. A visit is populated with tasks which define the work that will be done.
Visits appear on the Gantt within a plan, within the span of the plan's scheduled dates. They are either generated by the scheduling engine when the plan is created or when scheduling is manually run, or created as ad hoc visits. Once created, all visits are treated the same by the scheduling engine and on the Gantt.
The visit details appear in top left header of the plan when you single click the visit name. The following details are displayed in the header:
- Aircraft (subfleet)
- Aircraft tail and its associated subfleet.
- Visit Title
- By default, the visit takes its name from the task with the longest span.
- Slack
- The number of days between the Visit Start and Due Date of the first
due task.
- If slack is 1: The visit starts on the due date of the first due task, which will become overdue at midnight.
-
If slack is 0: The visit starts a day after the due date of the first due task. The aircraft should not be flown on this day.
- Track
- The track location where the visit is scheduled.
- Visit Start
- The day the visit is scheduled to start.
- Visit End
- The day the visit is scheduled to finish.

- Calendar Days
- The number of days the aircraft will be on the track. i.e. The number of Adjusted Work Days, plus the number of non-working days spanned by the visit.
- Standard Work Days
- The number of work days required for a visit, not adjusted by Track Proficiency.
- Adjusted Work Days
- The number of Standard Work Days divided by the proficiency factor.
- Travel Days
- The number of days the aircraft is in transit to or from the maintenance location.
- Driving Task
- The task in the visit with the earliest due date.
- Driving Task Due Date
- The due date of the driving task.
- Driving Task Spec Remaining
- The number of days, hours, or cycles of the driving spec for the driving task that will be remaining on the visit start date. (Hours and cycles values are forecasts.)
- Forecasted Cycles
- Based on the aircraft's forecast model and the visit's start date, the number of cycles before the task is due.
- Forecasted Hours
- Based on the aircraft's forecast model and the visit's start date, the number of hours before the task is due.
