About EASA FTL Calc
EASA OPS Rules for Flight Time Limitations (FTL) are valid since 18.02.2016.
EASA FTL Calc helps you to calculate
- cockpit and cabin limits
- actual and maximum flight duty periods (FDP)
- latest on-block times
- duty periods (DP)
- actual and minimum rest times
- state of acclimatization
- commanders discretion
- disruptive schedules
- required local nights at your home base
- extended recovery rest periods
- cumulative duties for 7/14/28 days
It considers
- standby and airport standby
- extension of cabin FDP due to earlier reporting time
- delayed reporting
- in-flight rest for cockpit and cabin (different rules)
- split duty
- extension
- positioning
- time zone differences
- company minimum rest times
- your home base
- "back to back" operation
You don't have to know time zones
- simply select an airport from the database
- time zone is determined by airport and date
- select only reporting airport of first duty day
- and the resting airport per duty day
- next reporting airport will be your last resting airport
- your home base will be known (preferences)
It's not a flight log
- you don't have to enter every single block time
- no management of block times and their cumulative limits
- however imported flights can be shown for information
Cabin and cockpit limits
- may have different reporting times
- in-flight rest is different
- are calculated independently
Rotations
- are stored automatically
- are shown in an own table
- with FDPs and rest times overview
- for cockpit and cabin
- on iPad in a split view
