Flight Time Limitations
FlightLog tracks your flight time and duty time against regulatory limits in real time, helping you stay compliant with FTL regulations.
Gauges#
The FTL screen displays visual progress bars for:
- Flight time – current accumulated flight time vs. the applicable limit
- Duty time – current accumulated duty time vs. the applicable limit
Each gauge shows:
- Current value
- Limit value
- Remaining time
Regulation-Specific Limits#
Flight time gauges adapt to your selected regulation:
| Regulation | Periods | Limits |
|---|---|---|
| EASA | 28 days, 12 months | 100h / 900h |
| FAA | 28 days, 365 days | 100h / 1000h |
| TCCA | 28 days, 90 days, 365 days | 112h / 300h / 1000h |
| CAAC | 7 days, 28 days, 90 days, 365 days | 40h / 100h / 270h / 900h |
| CASA (Australia) | 28 days, 90 days, 365 days | 100h / 300h / 900h |
Color Coding#
| Color | Status |
|---|---|
| Green | Safe – well within limits |
| Orange | Approaching – nearing the limit |
| Red | Near limit – close to or at the maximum |
28-Day Projection Chart#
Below the gauges, a chart displays your projected flight time over a rolling 28-day window:
- Past data shows actual recorded flight time.
- Future data shows projected flight time based on scheduled flights.
- A limit line indicates the regulatory maximum.
- A "NOW" marker separates past from future.
- Segments that exceed the limit line are highlighted with over-limit warnings.
Next Rotation PRO#
The Next Rotation card shows detailed analysis of your upcoming duty period:
- PEQ selector – choose 2, 3, or 4 crew members to adjust FDP limits
- Flight list – all sectors in the rotation with times
- Report time – local report time, calculated from the scheduled departure time (not actual departure) per regulatory requirements
- FDP analysis – current vs. maximum Flight Duty Period with color-coded status
- Extension (EXT) – available extension time when applicable
- Latest departure / arrival – computed butee times in UTC
- Taxi times – taxi-out/in and latest takeoff/landing times
All FDP and butee calculations use DST-aware UTC offsets, automatically resolved from the airport timezone and the flight date. This ensures correct results year-round (e.g. a winter departure from Paris uses UTC+1, while a summer departure uses UTC+2).
90-Day Currency PRO#
The dashboard displays a 90-Day Currency card that tracks your landing recency per aircraft type, as required by regulations (e.g. 3 takeoffs and landings in 90 days).
- Shows days until next landing is due for each aircraft type you fly
- Tap the card to see the full breakdown with currency status per type
- Color-coded: green (current), orange (expiring soon), red (expired)
Flight Time Calculation#
Flight time gauges use actual OUT timestamps (not scheduled departure times) for computing accumulated flight time, ensuring accuracy when actual times differ from the schedule.
Timezone Handling#
All FTL date calculations use outschedDate (the scheduled departure date) as the reference, preventing timezone shifts that could occur when using actual departure times across different time zones.
