## What is Part 117?

Part 117: FDP Tracker & Guide is a fast, glanceable assistant for airline pilots operating under 14 CFR Part 117. Set it up at show, glance at it mid-duty, and decide on extensions or overrides with the numbers in front of you — backed by a complete, searchable Part 117 reference.

DAY-OF-FLYING-TOOLS
- Live flight duty period (FDP) countdown from your report/show time
- Extension eligibility and countdown (+2 hours, §117.19) — shows your standing, not approval
- Maximum block time tracking
- Custom FDP override for company-specific limits
- Latest-takeoff planning so you know your last legal departure
- Acclimated-airport theater: bands use your acclimated airport's time zone, not device local time
- Airport search plus a nearby top-five picker, with IATA/ICAO display options

HOME AND LOCK SCREEN
- Home-screen widgets — duty needle gauge and max block (small and medium)
- Live Activity and Dynamic Island countdowns for one-second reads

FULL PART 117 REFERENCE
- Tables A, B, and C
- Key definitions and regulation sections
- Rest, reserve, and extension rules at your fingertips

IMPORTANT
This app is an educational reference and planning aid. It is not a scheduling system, a legal opinion, or a replacement for your certificate holder's policies, AIMS/company operations, or the Federal Aviation Regulations. Table C values are representative (commonly cited Class 1 rest-facility values); §117.17 has per-class variants. The pilot in command remains responsible for all duty, rest, and flight-time compliance. Always verify against current company guidance and the FAR.

## Version history (last 2 releases)

### 1.0.4 — 2026-07-19

Rest facility class is now part of augmented duty setup. Pick Class 1, 2, or 3 during pre-duty setup and your Max FDP updates to match that facility's Table C limit — no more assuming Class 1 for every crew.

The in-app Table C reference now shows all three rest-facility classes side by side (3- and 4-pilot values), matching the full federal table.

Accuracy fixes:
- Corrected the Table B limit for 2300–2359 report times at 3 segments (now 10 hours, per the CFR).
- Fixed the §117.11 flight-time reference text to state the correct limits.

Reliability:
- Fixed an intermittent hang when opening Table A, B, or C (and other Reference topics) on iPhone.

Under the hood, the app's regulatory tables and constants are now continuously checked against a pinned copy of 14 CFR Part 117 (current as of the July 2026 eCFR) to keep the numbers accurate.

### 1.0.1 — 2026-07-17

No release notes.
