• Start/End of Duty: Enter your local report time and release time.
• Flight Sectors: Select the total number of operated sectors (max 6).
• Discretion: Use only if properly applied by the commander. Tick +1h or +2h if used.
• Split Duty: If you had a rest of at least 3h in suitable accommodation, enter the duration. The FDP will be extended by 50% of that rest (up to +2h max).
• WOCL Penalty: If FDP overlaps the WOCL window (02:00–05:59 local), it is reduced by:
  – 30 minutes if the overlap is ≤ 2h
  – 60 minutes if the overlap is > 2h
• Max FDP: The limit is taken from EASA Table CS FTL.1.205(b)(1) depending on start time and number of sectors.
• 18h Awake Rule (STBY): If you had Standby before duty, the calculator will check that the combined Standby + FDP doesn’t exceed 18h awake limit, as per EASA GM1 CS FTL.1.225(d). The awake time is calculated from:
  – 07:00 local if STBY between 23:00–06:59
  – 10:00 local if STBY between 07:00–19:59
  – 19:00 local if STBY starts at 20:00 or later
  – Or from time of callout if known (used if earlier)
• Violations: If your duty exceeds FDP, WOCL, or 18h awake, warnings will be shown with explanation.
• Result: The calculator shows whether the duty is legal, and provides a breakdown of penalties and extensions.

Disclaimer:
This Flight Time Limitations (FTL) calculator is designed to assist professional pilots in evaluating duty and flight time legality under EASA regulations. It follows the official rules outlined in:

• CS FTL.1.205(b)(1) – Maximum FDP depending on start time and sectors

All calculations are based on local time. The tool does not replace airline-specific SOPs, internal fatigue management systems, or operational control systems. Pilots remain fully responsible for ensuring operational and regulatory compliance.

This tool is intended for offline use during flight preparation or briefing, and reflects EASA rules valid at the time of development. For official and updated guidance, always refer to EASA documents and your operator's manual.
