Student Solo Endorsement Tracker

The 61.87(n) solo endorsement is valid 90 days — after that the instructor must re-endorse, having determined continued proficiency. Cross-country solo endorsements under 61.93 are per-flight. For a CFI with several pre-solo and solo students, the 90-day clocks all run independently; this tracker shows each student's expiry as a colour badge so nobody shows up to solo on a dead endorsement.

61.189(c) requires instructors to keep a record of endorsements for knowledge and practical tests, and solo endorsements, for at least 3 years — including the kind of test or check and the result. Many instructors keep them for their entire career because renewal-by-activity, Gold Seal applications and employment verification can reach back further than the regulatory minimum.

No — Part 141 schools and most 61 academies maintain their own official training records, and those remain the documents of record. This is the instructor's personal layer: your portable evidence of activity that survives job changes, school closures and software migrations, in a plain CSV you control. The two should agree; yours is the one you can produce in five seconds.

Clearing site data or doing a full browser reset deletes locally stored entries — that is the price of a genuinely private, server-free design. Protect yourself with the one-click CSV download before any cleanup, OS reinstall or new laptop: re-importing your history later is far easier than 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, every major electronic logbook can map it on import, and a printed copy is perfectly legible to a human reviewer. Nothing proprietary means your instruction record is never trapped here.
