Real-Time Fleet Status

Usage tracking feeds accounting and maintenance status.

After each flight, your customers will create a usage entry that logs hobbs, tach, cycles, landings, oil consumption, or any other custom 'timer' that you configure. Customer accounts are automatically billed and the aircraft maintenance statuses updated. Customers may also report squawks after their flight.

Aircraft maintenance status is shown next to the aircraft in the calendar and on a master Fleet Status report.

Flight time based maintenance reminders are predicted based on usage analytics that convert "10 hours due" to "predicted due date is Monday."
