About Centerline Scheduler
Centerline is a free, independent mobile app for pilots at flight schools and flying clubs that use ScheduleMaster. Sign in with your existing club credentials and run your flying from your phone. Book, cancel, preflight, and postflight on the ramp, in the plane, or between meetings. PLAN AND BOOK - Dashboard: active bookings, upcoming reservations, past flights, currency at a glance, and your running statement balance - Day and week schedule: the entire club fleet in one view, tap for detail, pinch to zoom the ribbon, drag to shift the window - One-tap booking: pick an empty slot on any aircraft's ribbon, fill four fields, tap Book - Linked accounts: pilots at multiple clubs sign in once and switch without retyping credentials FLY - Preflight and postflight: Hobbs and tach entry, no-flight and maintenance modes, receipt items - ForeFlight export: send completed flights straight to your logbook - Live Activities: your reservation, the weather, and squawk status on your lock screen - Aircraft alerts: get a push if a plane you booked changes rate, picks up a squawk, or gets grounded before you fly SHARE - Instructor and student links: CFIs pair with students to see upcoming lessons and share currency at a glance - Rideshare: offer a right seat on a cross country you are planning, or ride along on someone else's - Google Calendar sync: every booking mirrors to your personal calendar, optional, connect once in Settings Dark mode, dynamic type, and safe-area aware throughout.
