Aviation Training Device (ATD) Time Log
Session log for BATDs and AATDs — device, tasks, approaches and credits tracked separately from aircraft time, export-ready.
Credit rules: AATD time credits up to 10 hours toward the IR (BATD also accrues limited credit) and satisfies 61.57(c) instrument currency without an instructor present.

About Aviation Training Device (ATD) Time Log
Simulator credits are real money — AATD time credits up to 10 hours toward the IR (BATD also accrues limited credit) and satisfies 61.57(c) instrument currency without an instructor present — but they're device-specific, which makes the recordkeeping the whole game: time in an unidentified 'sim' credits nothing. This log captures each session with the device and its qualification level, duration, approaches, holding and content, then maintains device-hour totals and the rolling six-month approach count that currency planning runs on. Keeping it separate from aircraft time isn't pedantry; it's how the credit survives the audit, and it's how you discover that your winter currency plan can run on the cheap box instead of the expensive aeroplane.

Frequently asked questions
Can I keep instrument current entirely in an AATD?+
Largely, yes: current 61.57(c) language allows approaches, holding and tracking flown in an approved ATD to maintain instrument currency without an instructor on board, making a $60–120/hour AATD the cheapest legal currency there is. The catch is documentation — log the device model, its FAA approval (LOA), and the tasks per session, because 'AATD time' without the device identity doesn't survive scrutiny.
Why must the device identity be logged every session?+
Because every credit rule is conditioned on the device's qualification: an AATD's letter of authorization, an FTD's level, an FFS's C/D qualification. The same hour of 'sim' credits 0, 10, 20 hours — or a type rating — depending on that identity. Sessions logged with device and level are auditable; sessions logged as 'sim, 1.5h' are donations.
Is simulator time flight time?+
No — it's training/simulator time, logged in its own column, and conflating the two is among the fastest ways to have an entire logbook questioned. Totals here stay separate by design. Where sim time legitimately substitutes (IR hours, currency tasks, checks), it does so under explicit rules as SIM time; the credit comes from the rule, not from relabeling.
Where is my logbook data stored?+
Everything you enter is saved in your browser's local storage on your own device — nothing is uploaded to any server. That means your flight records stay completely private, work offline, and load instantly. Use the CSV export regularly to keep an off-device backup copy of your records.
Can I get my data out if I switch tools later?+
Always — the CSV export is a complete, lossless dump of your simulator record, generated locally in one click. Import it into commercial logbook software, archive it in your records folder, or post-process it in a spreadsheet. No lock-in is a deliberate design decision: data you can't take with you isn't really yours.
