FAR 117 Table B Reference
Max FDP — the reference table, properly sourced, with the reading rules that make it usable.
The table's shape IS the fatigue science: early-morning and late-night reports lose hours, and every segment past the second costs more.
Max FDP (hours) — acclimated, unaugmented (14 CFR 117 Table B)

About FAR 117 Table B Reference
Some aviation questions deserve a table, not a calculator: max fdp (hours) — acclimated, unaugmented (14 cfr 117 table b). This reference presents it cleanly with its source (14 CFR Part 117, Table B) and the operational reading that makes it usable — because the table's shape is the fatigue science: early-morning and late-night reports lose hours, and every segment past the second costs more. Bookmark-grade utility for flight bags, crew rooms and study: the five-second lookup that otherwise means hunting through the rule text.

Frequently asked questions
How do I read FAR 117 Table B?+
Row by scheduled report time (local, acclimated theatre), column by the day's flight segments: a 0715 report with four segments reads 13 hours of maximum FDP. Non-acclimated crews subtract 30 minutes from the table value; augmented operations use Table C instead; and the cumulative fences of 117.23 apply over everything. The table rewards schedule literacy — knowing the row boundaries explains why crew scheduling fights for an 0700 report over an 0655.
Is this table authoritative for operations?+
It's a faithful working summary, sourced to 14 CFR Part 117, Table B — but tables in tools, apps and even ops manuals are copies, and the rule text plus your operator's approved scheme govern when anything disagrees. Use this for speed and study; cite the regulation for decisions that get audited. The source line exists precisely so verification takes one lookup.
Is this tool private — who can see my entries?+
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, export a CSV backup before clearing browser data or switching computers.
How do I back up or print these records?+
Use the Export CSV button below the table: it downloads your full reference data as a spreadsheet-ready file. From there you can print a clean copy, archive it with your records folder, or import it into any other system. Exporting monthly is a good habit since the working data lives only in your browser.
