Most private pilots do not lose hours in the air. They lose them on the ground — a wet bag, a running total that drifted, a page they cannot read when insurance asks for the last 90 nights.

A logbook is a legal record, not a diary. Treat it that way.

1. Log the flight the same day. Memory is not a source document.

2. Write night from official end of evening civil twilight, not from “it felt dark.”

3. Keep a running total you can audit. If PIC plus dual does not make sense against total time, fix it that week, not at renewal.

4. Photograph every paper page before you retire the book. Paper fails once.

5. Export a copy off your device. A record that lives in one place is still a single point of failure.

That is the whole discipline. The tool should make it faster, not cleverer.
