sFTL – Flight Time Limitations

sFTL is the flight time limitations companion built for airline crews. Enter your report time and sectors, and sFTL answers the question that matters on the flight deck: what is the latest on-blocks time for this duty?

Built on EASA ORO.FTL, sFTL works entirely offline and recalculates as soon as anything changes.

THE ANSWER FIRST
- Maximum FDP shown as a clock time: latest on-blocks in UTC or local time
- Planned margin on one clear status scale: green, amber, red
- Every option with its own clock time: extension, split duty, commander discretion
- Live "Time left" countdown while on duty

EASA ORO.FTL RULES
- Acclimatised (Table 5) and unknown state of acclimatisation (Table 6)
- Augmented flight crew with in-flight rest: 3 or 4 pilots
- Flight crew and cabin crew
- Delayed reporting and split duty
- Minimum rest after duty and earliest next report
- WOCL encroachment and cumulative limits for reference

SECTORS AND TIMELINE
- Up to 10 sectors with airport search and automatic local times
- Times entered on a numeric keypad, with ±1 / ±10 minute nudges
- Duties crossing midnight handled automatically
- Clock-time timeline with sectors, WOCL, crew rest window, limits and a "now" cursor

CREW REST
- Rest rotation for 3 or 4 pilots with planned slots per pilot or pair
- Arm the cruise for the planned start, or start it now
- Fine-tune the rest start after OUT with − / +, right up to the moment the rest begins
- Alerts before and at the end of each rest period
- Ongoing lock-screen notification with the current rest period and countdown
- Hold to stop, so the alerts are never cancelled by accident

NEARBY SHARE
- Send the whole duty, sectors and crew rest to crew members nearby in one tap
- Works over Bluetooth with sFTL on Android and sQRH on iPhone and iPad — no pairing, no account, no internet
- The receiver always sees a summary and chooses to accept or decline

BUILT FOR THE FLIGHT DECK
- Works fully offline; nothing leaves your device except what you choose to share
- Phone and tablet layouts, light and dark mode
- Your duty is kept exactly where you left it

sFTL is an aid, not an authority. Always cross-check against your operator's approved FTL scheme and the applicable regulations.

What's new in 1.1
- Crew rest: adjust the rest start (OUT + X min) with − / + before the rest begins, also once armed; the armed start follows. Hold a button to step faster.
- Rest start buffer up to 180 minutes.
- Crew rest card easier to read: larger, high-contrast times for the rest periods and the rest window.
