Avionics Discrepancy Log
Structured discrepancy tracking for owners of glass and mixed panels: report, status, disposition and dates — with open-item badges.
Avionics faults are intermittent by nature — the GPS that resets once a month will NEVER do it in the shop; the dated pattern of occurrences IS the diagnostic.

About Avionics Discrepancy Log
Avionics faults are intermittent by nature — the GPS that resets once a month will NEVER do it in the shop; the dated pattern of occurrences IS the diagnostic. The cure is structural, not motivational: a single shared list where every observation lands with severity, status and dates, and where 'open' is a visible badge rather than a memory. That's this log. Write-ups take thirty seconds; the status field tracks each item to closure; the summary counts what's open and deferred so nothing ages into folklore. The export gives your mechanic a worked discrepancy history instead of a verbal handover.

Frequently asked questions
How do I get an intermittent avionics fault diagnosed affordably?+
Bring the shop a pattern, not an anecdote: date, phase of flight, what failed, what else was on, ambient conditions, exact messages. Five such entries often localise a fault (always after long taxi in heat = cooling; always on COM1 transmit = coax/connector) before any bench time is billed. This log's structure exists to capture exactly those correlates while they're fresh — your avionics bill is inversely proportional to the quality of this record.
How detailed should a discrepancy entry be?+
Enough that a stranger could act on it: what, when noticed, conditions, and any pattern ('right fuel gauge reads zero for first 10 minutes, cold mornings only'). Severity and status make it actionable; the date makes it evidence. The one-line vague entry — 'radio weird' — costs more shop time than it saves writing time, which is the entire economics of doing this properly.
Do I need an account or internet connection?+
No account and no connection are needed once the page has loaded — records live in local storage on your device and every calculation runs in your browser. Data doesn't sync between devices, so export the CSV when you want to move or archive your records.
Can I export these records for an audit?+
Yes — one click exports your complete discrepancy history as a CSV file that opens in Excel, Google Sheets or Numbers. The export preserves every column exactly as entered, so you can print it, attach it to paperwork, or hand it to an inspector, buyer or insurance underwriter as a supporting summary alongside your official records.
