KC Crew Planning Acclimitization

Chapter 1: Introduction

  • Acclimatization and its impact on flight safety discussed.

  • Fatigue is a serious form of tiredness affecting performance.

  • The biological clock (circadian rhythm) plays a key role.

  • Question: How does the biological clock align with the local timezone during travels?

  • Personal experience: sleeplessness upon arrival in a new timezone due to misalignment of biological clock.

  • The shift of the biological clock depends on time zone differences and the duration of stay.

Chapter 2: Time Zones and Acclimatization

  • Definition: A crew is acclimatized when their biological clock syncs to the local time of the departure station within two time zones.

  • Reference Time: Local time at the departure station in relation to new destination.

  • Example given: If acclimatized to Paris, still acclimatized within two time zones.

  • Factors affecting acclimatization:

    • Time difference between departure and arrival stations.

    • Time interval between check-in at departure and next station.

Chapter 3: Status of Acclimatization

  • Three statuses based on variables: B, D, X.

    • Status B: crew remains acclimatized to the departure station.

    • Status D: crew is acclimatized to the next station.

    • Status X: crew is not acclimatized; biological clock is out of sync.

  • Status determines maximum flight duty period before departure from the next station.

  • Special table for status X due to lack of biological timing information.

Chapter 4: Utilizing Oro FTL

  • Required resources: Oro FTL, Article 105 for acclimatization table and Article 205 for maximum flight duty periods.

  • Check-in times in UTC must be converted for local time assessment.

  • Example: Crew based in Amsterdam, acclimatized to local time.

  • Calculation: Local time for Amsterdam is UTC+2, e.g. 5:00 UTC means 7:00 local time.

Chapter 5: Amsterdam-Curaçao Flight Example

  • Maximum Flight Duty Period (FDP) determined to be 13 hours for a flight from Amsterdam to Curaçao based on variables utilized.

  • Variables include:

    • Time difference: UTC+2 for Amsterdam and UTC-4 for Curaçao, resulting in a 6-hour difference.

    • Time elapsed between check-ins computed for additional consideration.

Chapter 6: Acclimatization Status at Curaçao

  • Total elapsed time: 39 hours leading to status B when checking in at Curaçao.

  • Status B indicates acclimatization to Amsterdam time.

  • Reference the acclimatization table to ascertain appropriate flown schedule.

Chapter 7: Conclusion

  • Maximum FDP of 11 hours calculated based on crew's acclimatization status to Amsterdam time upon check-in at Curaçao.

  • Acclimatization table confirms duty time allowed based on these parameters.

  • This knowledge clip concludes with proper methodologies for assessing acclimatization and its impact on flight safety.
