Viewing due dates and recurrences of tasks

On Maintenix pages that list tasks, the predicted due date for a task is shown, along with other information—such as the extended deadline when applicable and, for recurring tasks, the repeat interval. You can use this information to decide when to execute a particular task. This applies to tasks based on a task definition, and to ad hoc tasks.

For recurring tasks, you can see how much of the repeat interval has been used up already, and how much yield has been achieved since the last time the task was performed.

This information is shown in the Due column (see the figure) that appears on the following Maintenix pages:

Figure: Due column

The content of the Due column differs slightly depending on whether the task is recurring, and if the task deadlines are specified using a usage parameter or a calendar parameter.

For non-recurring tasks, only the next due date is shown. If the task deadline is based on usage parameters, the due date is the predicted due date, which is based on the usage forecast from the flight schedule and forecast model. If the deadline is based on calendar days, the date shown is the actual due date.

For deadlines based on usage parameters, you see the following information:

• The remaining usage before the task is due. If a deadline extension was added to the task, the sum of the remaining usage and the extension is shown in parenthesis.

• The predicted due date. This is not shown if the target inventory of the task is loose—not installed on an aircraft.

• The repeat interval, for recurring tasks only.

For deadlines based on calendar parameters, you see the following information:

• The due date.

• The extended due date, which is the date that corresponds to the due date plus the deadline extension that was added to the task.

• The repeat interval, for recurring tasks only.
