    Study Notes

    Airline Crew Planning

    • Course: AVIA 3201 Airline Resource Management
    • Topics: Aircrew Planning & Utilisation, Crew Utilisation, Pattern Planning, Crew Establishment Planning
    • Instructor: Dr. C. Richard Wu, UNSW Aviation
    • Memoriam: Ms. Deborah Cybula

    Air Crew Planning Process

    • Aircraft (Routing) Schedule is the starting point
    • Followed by Crew Pairings/Patterns
    • Then Crew Rosters (Domestic: one month in advance)
    • Finally, Day of Operations

    Air Crew Utilisation

    • Number of crew needed depends on:
      • How hard the aircraft is flown
      • How efficiently the crew are utilized
    • Efficiency factors:
      • Number of days the crew fly
      • Amount of flying per day

    Available Roster Periods Per Annum

    • 12 Calendar Months
    • 365 Days
    • 1.5 x Annual Leave Periods (42 Days)
    • 10.5 x Work Periods

    Available Flying Days Per Roster Period

    • 30 (or 31)-day Roster or 28-day Roster
    • 9 Days Off
    • 20 (or 21) Days Flying
    • 1 Training Day

    Available Flying Days Per Annum

    • 10.5 Roster Periods x 20.5 Flying Days per Period = 215.25 (Maximum)
    • Rounded down to 200 (for ad hoc absences)

    Average Block Hours Per Day

    • Varies by day
    • Example data provided showing Block Hours for specific days

    Maximum Block Hours Per Annum

    • 200 Flying Days
    • Average Block per Day is 4:15
    • 850:00 Block Hours per Annum
    • Note annual flying hour limits

    Crew Per Aircraft (Domestic)

    • Aircraft Annual Block Hours (Domestic): 4,000 hours
    • 701 hours per crew
    • Crew count per aircraft: 5.70
    • Note: avg aircraft utilization is ~11 hours per day; 11 x 365= 4015 hours/yr

    The Impact of Premium

    • Premium formula: ((CreditHr-BlockHr) / BlockHr) x 100%
    • Higher premium = higher credit hours
    • Credit hours include flying and non-flying duty hours
    • Cabin crew are paid and rostered to credit hour limitations
    • Flight and cabin crew recruitment is planned according to current premium levels
    • Used for both short and long-term crew planning

    What is Premium?

    • Premium describes synthetic credit above actual block hours flown by the aircraft
    • Synthetic credit includes non-block activities
      • Sign-On & Sign-Off time
      • Paxing (or positioning/deadheading)
      • Time spent in transit (aircraft turnaround)
      • Minimum Credit Guarantees (if applicable)

    The Impact of Premium on Rosters

    • Data showing block hours and synthetic hours for different premium percentages. Impact on number of flying lines for different premium scenarios

    Impact of Premium on Pairings

    • Premium formula
    • Data showing example pairings with detailed times for different sectors including block hours and synthetic credit
    • Example of savings with two crews vs one crew

    Premium is Sensitive to Network

    • Data illustrating how different sector lengths impact premium

    Drivers for Pairing/Pattern Planning

    • Minimise Premium
    • Maximise Flown Block Average
    • Minimise Paxing (positioning/deadheading)
    • Minimise Time Away From Base
    • Minimise Hotels
    • Minimise Equipment Change
    • Sync with Aircraft routing

    Push to Lower Premium - Hotels & Paxing

    • Driving down premium by reducing unnecessary credit hours (e.g., paxing)
    • Increasing hotel nights is correlated with longer patterns/lower
    • Daily density is lowered due to longer patterns as a result of premium reductions

    Hotel or Paxing?

    • Graphs illustrating flight patterns with potential hotel or paxing times for specific days

    Long Term Crew Establishment Planning

    • Total aircraft block hours for two fleets (B737 & B767)
    • Number of cabin crew for B737 and B767
    • Total crew block hours calculations

    Crew Establishment and Strategic Planning

    • Total Crew Block Hours (B737 & B767)
    • Average crewing premium for a given period (56%)
    • Total crew credited hours for the period
    • Number of personnel needed (198)

    Min Flying Requirement, Reserves, Vacations etc

    • Minimum crew requirement
    • Reserves
    • Vacation
    • Recurrent Training
    • Ground Duties
    • Total demand for various crew types.

    Classroom Exercise

    • Three A330 services per week: SYD/KUL return
    • Flight times: SYD->KUL (8:00 hours), KUL->SYD (7:00 hours)
    • Cabin crew complement: 1 CSM, and 7 FA
    • Sign-on time: 1:15 hr
    • Sign-off time: 0:30 hr
    • Calculate premium for the pattern/pairing

    Answer to Classroom Exercise

    • Block hours calculation
    • Duty hours calculation
    • Premium calculation (23.33%)
