Reserve aircraft without double-booking, keep squawks in front of everyone, and know exactly how many hours are left before the next inspection.

A timeline per airplane per day. Overlapping bookings are rejected by the database, not by hope.
Any member can file a discrepancy with severity. Grounding items are impossible to miss on the fleet page.
Annuals, 100-hours, ELT batteries and pitot-static checks tracked by both calendar date and Hobbs time.
Post-flight Hobbs and landings roll straight into the aircraft's recorded time.
Attach a CFI to any reservation so dual instruction shows up on the same board as rentals.
Members, instructors and admins. Only admins touch the fleet, maintenance and permissions.
