Aviation lives on inspection schedules. Ground support equipment, calibrated tools and test devices all have dates that cannot slip.
A label on every tool
Stick a QR label on each tool or vehicle. A scan shows its calibration date, the responsible shift lead and the last service.
Dates that watch themselves
Calibration and inspection reminders go to the responsible person and the manager, so a torque wrench never silently goes out of date.
Ready for the audit
Every update and approval is in the activity log. Filter by user or period and export to Excel when the auditor asks.
