Spin Training Endorsement Log

Training in CFI applicants (spin entry, spins and recovery), working through stall awareness, spin entry, developed spins and recovery technique in a spin-approved aircraft, concluded by a logbook endorsement from an authorized instructor certifying proficiency. required for initial CFI; many pilots take it voluntarily for upset recovery skill. There is no minimum hour requirement in the rule itself — proficiency is the standard — but insurers frequently impose their own minimum dual hours, which is why the running dual-time total here matters beyond the legal endorsement.

Legally no — the 61.31-style endorsement doesn't lapse. Practically, maybe: after long inactivity, clubs and insurers commonly require a re-checkout with an instructor, and proficiency itself fades faster than paperwork. The stage field here separates original training, the endorsement flight and recurrent practice, so the full arc stays readable years later.

No — the rule sets proficiency, not hours, so your instructor signs when you're ready rather than when a counter hits a number. The practical budget depends on background and the aircraft, and the binding constraint is often insurance: underwriters attach their own dual-hour minimums to CFI applicants (spin entry, spins and recovery), sometimes above the point where your CFI would happily endorse. The dual-time total this log maintains is the number both conversations need.

Only you. Entries live in your browser's local storage and never leave your device, so there is no account, no cloud sync and no one else with access. Because the data is device-local, remember to export a CSV backup before clearing browser data or switching computers.

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 training record is never trapped here.
