Aviation Tools Built by Pilots, for Pilots
Meet Part 117: FDP Tracker & Guide — track your Flight Duty Period limits, rest, and cumulative duty in real time, and always know exactly where you stand.
Everything you need to stay legal
Part 117 makes the call on your duty day. Our app does the math so you don't have to.
Real-Time FDP Limits
Enter your report time and number of segments to instantly see your maximum Flight Duty Period under the Part 117 tables — with a live countdown as your day unfolds.
Rest & Lookback Tracking
Track required rest periods and rolling lookback windows so you can confirm you're legal before you accept an assignment, not after.
Cumulative Duty & Flight Limits
Monitor cumulative flight time and duty against the 60/100/190-hour and other rolling limits, with clear visual indicators as you approach a cap.
Built-In Part 117 Guide
A plain-language reference to the regulation's key tables and definitions, right where you need it — no thumbing through the FOM at 3 a.m.
Designed for the flight deck
Glanceable, fast, and focused — built for the way pilots actually work.
