EASA FTL Assistant

EASA FTL Assistant is a robust, no-nonsense flight duty calculator designed specifically for the flight deck. Built with a high-density, dark-mode EFB aesthetic, it provides professional airline pilots with quick and accurate calculations for Flight Duty Periods (FDP) and rest requirements under EASA ORO.FTL regulations.

Whether you are managing complex acclimatisation states, calculating split duties, or evaluating Commander's Discretion limits, this tool processes the rules locally on your device—no internet connection required.

CORE FEATURES

Basic FDP Calculation: Instantly calculates maximum FDP and expiry times based on Table 2 (acclimatised) and Table 3 (unknown state of acclimatisation).

Acclimatisation Tracking: Evaluates your precise state (B, D, or X) based on time zone differences and elapsed time since reporting.

Standby & Split Duty: Accurately calculates FDP reductions for Airport and Other Standby, plus extensions for qualifying ground breaks.

In-Flight Rest Extensions: Supports augmented crew calculations for Class 1, 2, and 3 rest facilities.

Unforeseen Circumstances: Calculates revised limits for delayed reporting and Commander's Discretion, including mandatory authority reporting thresholds.

Disruptive Schedules: Automatically detects WOCL encroachment, night duties, and early/late disruptive schedules.

DESIGNED FOR PROFESSIONAL USE

EFB-Optimized Interface: A high-contrast, dark-mode UI tailored to preserve night vision in low-light cockpit environments.

Transparent Logic: The app doesn't just give you a number. It provides step-by-step rule explanations (e.g., "Why this limit applies") so you can verify the calculation logic against your OM-A.

Offline First: Pure calculation logic that works perfectly in airplane mode.

Disclaimer: EASA FTL Assistant is a planning aid only. It does not replace your operator’s Operations Manual (OM), approved FTL scheme, current regulations, or standard operating procedures. Always cross-check calculations.
