Flight Logs & Time Tracking

A logbook that catches its own typos

Hobbs and tach captured the moment you shut down, then checked against the engine's own math. Storing flight logs is table stakes. Centerline audits them.

Closing out a flight takes one workflow, not a memory

The flight you're on shows up as a Current Flight card on both the dashboard and the Flight Logs screen, with a Finish Flight button that stays available for an hour and a half after the scheduled end, so a delayed pilot isn't racing the app. The guided dialog behind it records hobbs and tach start and end, fuel added, oil added, and comments, plus a cost summary step when billing is turned on. Entering 1247.8 on a phone at the airplane is a drag, not a chore: press and drag up or down on either side of the number, with mouse or touch. Off-field fuel gets a camera or photo picker instead of a text message to the treasurer. And a member with a flight already in progress is nudged straight into that workflow instead of being offered a manual entry that could duplicate it.

The intelligence

Storing flight logs is table stakes. Auditing them is not.

Two pilots log within minutes of each other. One types the start tach wrong. Under most systems that's a wall of red warnings and an evening of detective work.

Centerline reads each entry against the one before it and tells you what's actually wrong. Forgot the end tach? It back-computes the right number from that aircraft's own tach-to-Hobbs ratio (the median across every clean flight it has ever logged, with at least three samples required) and offers it as a one-click "Use" button. Tach impossibly higher than Hobbs? Same treatment. A single upstream typo cascading into a run of downstream warnings? It traces the cascade and, when the typo is clearly on one side, points straight at that row instead of leaving you to check both.

No AI and no guessing: deterministic arithmetic, the same math your A&P would do by hand.

Gap detection
The logbook tells you it is incomplete instead of quietly being wrong, and closing a gap takes seconds.

Rule-based suggested fixes
Typos are caught at the source, the system knows what the number should have been, and 12 red warnings turn back into 1 real problem, all of it explainable to an A&P.

Records that stay trustworthy

Every tail keeps its own full history: automatic hour calculation, running totals, and a filter down to a single pilot's flights on that aircraft. Flights flagged as maintenance never generate a charge, and once a billing entry exists for a log, editing, deleting, or re-finishing it is blocked on the server, not just hidden on the screen. Corrections route through an admin who fixes the log and the charge together. Until then, members clean up their own unbilled typos without filing a support ticket. Aircraft without a Hobbs meter can turn tracking off entirely, which hides Hobbs from entry forms, the list, cost summaries, rate setup, and the CSV export, and every export carries the right columns for how the aircraft is configured.
