Flight Time Limitations (FTL): Structure of Calculations

 

2-1

 

Structure of Calculations

  1. Time Limits in Consecutive Periods
  2. Maximum Flight Duty Period (FDP)
    1. Determine Status of Acclimatization
    2. Maximum FDP for Acclimatized Crew
      1. Basic Daily FDP
      2. Reduction by number of legs
      3. Reduction by Encroachment with Window of Circadian Low (WOCL)
        1. Calculate WOCL
        2. Calculate WOCL Encroachment
        3. Calculate WOCL Reduction
    3. Maximum FDP with Unknown State of Acclimatization (NO FRM)
    4. Maximum FDP with Unknown State of Acclimatization (FRM Implemented)
    5. Extensions
      1. Standard Extension
      2. Split Duty
      3. Augmented Crew - In-Flight Rest
  3. Rest
    1. Minimum Rest Before FDP
    2. Rest Regarding Time Zone Change
  4. Periodical Rest Periods (Local Days Off)
  5. Standby / Reserve
