Maintenance Check Types
Check types are templates that define standard maintenance requirements used across your fleet. These are reusable definitions that specify:- Name of the maintenance requirement
- Interval (hours or calendar days)
- Whether it’s hours-based, calendar-based, or both
Example Check Types
Maintenance Check Items
Check items are the actual maintenance records assigned to specific aircraft. When you assign a check type to an aircraft, it creates a check item that tracks:- Which aircraft it applies to
- What type of check it is
- When it’s due (hours and/or date)
- When it was last complied with
Example Check Item
How the System Calculates Remaining Time
For Each Aircraft
The system continuously monitors:- Current aircraft hours (from flight logs)
- Today’s date
- All active check items for that aircraft
Calculation Examples
Hours-Based Check:
Calendar-Based Check:
Combination Check (whichever comes first):
Aircraft Status Display
The system shows the most limiting check for quick reference:Most Limiting Hours Check
Display: “100-Hour due in 21.6 hours”
Most Limiting Calendar Check
Display: “Annual due in 64 days”
