Color bars for maintenance reminders indicate the remaining times/hours. Yellow indicates 10% remaining or less. Red indicates 2% remaining or less.
You can find them by selecting:
Manage > Aircraft > (click one) > Reminders.
Reports > Maintenance Reminders.
Dispatch reservation > Click Maintenance.
Basic users are prevented from dispatching if expired maintenance reminders or new/pending squawks (in that status only). If a specific maintenance reminder is not an airworthy issue, like ‘Wash Plane’, you can disable it from preventing dispatch by editing that reminder specifically.
You can do this at Manage > Aircraft > Reminders > Edit anyone of them and uncheck the box “If this reminder expires, prevent dispatch for basic users.” Only admins can change this. Admins, instructors, and any user in a Group with Maintenance = YES, will be able to override
Set custom time periods for email alerts for Maintenance Reminders:
For Meter Based you can set percent and hours remaining and for Time Based you can set percent, days, and months remaining.
