Aircraft Booking & Maintenance Conflict Board

By forcing both calendars onto one board: inspection due-dates (and hours remaining converted to dates at current utilisation) beside the heavy booking commitments — checkrides, stage checks, weekend blocks. Conflicts become visible at two weeks instead of two hours, and the fix is cheap: shift the 100-hour to Tuesday, move the checkride to the other 172. The board IS the meeting; most schools that run one stop having the Friday grounding conversation entirely.

Scheduling apps optimise the future and discard the past — cancelled bookings vanish, dispatch details live in fields nobody exports, and the historical pattern (the thing audits and retention analysis need) is unreachable. This log is the durable record layer: simple, structured, yours, exportable. Many schools run both: the app for tomorrow, this board for what actually happened.

Clearing site data deletes locally stored entries — that's the price of a genuinely private, server-free design. Protect yourself with the one-click CSV download before any cleanup, OS reinstall or device change: re-importing history later beats reconstructing it from memory.

A plain CSV with one row per entry and labelled column headers — the most portable format there is. Spreadsheets open it directly, most specialised software can map it on import, and a printed copy is perfectly legible to a human reviewer. Nothing proprietary means your operations record is never trapped here.
