Logbooks that catch their own typos, instructor invites, and smarter back-early alerts

Smart Flight Log Error Detection — and One-Click Fixes
Two pilots logging at the same time. A start tach typed wrong. An end tach forgotten. They used to cascade into walls of red "missing log entry" warnings that made it hard to tell what actually happened.

Now Centerline reads each entry and tells you what's wrong:

  • Forgot the end tach? A small ⚠ appears on the row, and opening it shows a calculated suggestion you can apply with one click.

  • Tach time impossibly higher than Hobbs time? Same thing — Centerline back-computes the correct start tach from the end value and offers it as "Use 2417.80".

  • Started below the previous flight's end? A "Use Y.YY" button right in the dialog.

  • Real gap between two flights? The "Possible missing flight" banner now opens a pre-filled form so you can drop in the missed entry without retyping anything.

  • Cascading inconsistencies caused by a single upstream typo? Centerline now traces the cascade and points you at the row that's actually broken with "Likely typo on row above — Tap to fix".

Suggested values are derived from the engine itself: hobbs and tach counters move together with a steady ratio, so we use each aircraft's typical ratio (computed from your last clean flights) to back-calculate what the missing number should be.


Flight Logs Got a Cleaner Layout

While we were in there:

  • Sorted by tach instead of entry date — flights now show in actual engine sequence, so two pilots logging at nearly the same time can't accidentally appear out of order.

  • One aircraft at a time — the "All Aircraft" filter is gone. Per-aircraft tach values weren't comparable across the fleet anyway, and gap detection now actually means something.

  • Hobbs and Tach columns show start → end in a single line so you can see the full flight at a glance.

  • The redundant Aircraft column has been removed (you're already filtered to one).


Instructor Calendar Invites

When a student adds a CFI to a reservation, the instructor now gets a confirmation email with a calendar invite (.ics), an in-app notification, and an SMS — all with wording that addresses them as the instructor instead of the pilot. Reservation updates and cancellations notify them too. If the assigned CFI changes mid-flight, the old instructor gets a cancellation and the new one gets a fresh invite. If you're a CFI, this is the "can I get notified when a student books me?" feature you asked for.


Maintenance Contacts on Maintenance Reservations

Click any maintenance reservation on the calendar and you now see a list of people to contact: the organization's maintenance officers and any aircraft-specific contacts you've set up, with little role icons next to their names. No more guessing who handles squawks for which plane.


Back-Early Notifications, Now Smarter

Previously, when someone ended their flight early enough to free up the aircraft, every member of the club got pinged. Useful, but noisy. Now, only the next pilot scheduled on that aircraft within the next 24 hours gets the notification, the person who actually has a chance to use the freed-up time. If nobody's queued, no notifications fire. The per-aircraft "Back Early" mute toggle still works.


Smaller Fixes Around the App

  • Billing actions on the logs page are now restricted to Owner and Booking roles. Members no longer see the create-billing button or column.

  • Comments field on the new- and edit-log dialogs is now a single-line input instead of a multi-row text area — most pilots use it for one short note.

Clear skies and tidy logbooks,
