Temperature Profiles used for
Cool Container planning and day-to-day operations.

Examples of airline catering temperature profiles listed below shows typical activities, default periods and prevailing circumstances which may apply.

    • TP-01 – Default = 8 Hours.

    • Please start pre-condition as early as possible with minimum 8 Hours prior to loading.

    • Install 100% recharged battery

    • 4 x green LED lights must be shown

    • Set Temperature = 4 ºC to be retained.

    • Additional dry ice to be placed in Cargo Compartment subject to ambient temperature.

    • TP-02 - Default = 1 Hour

    • Install 100% recharged battery

    • 4 x green LED lights must be shown

    • Record time for loading, door opened and closed = 7 Min.

    • Total loading time is estimated to be 1 Hour from Container in place, trolleys, boxes, ovens ready available, placed inside the Container and Aft Doors closed.

    • Actual time during which the aft doors are opened for loading and storage shall be kept to a minimum in order to avoid loss of temperature controlled airmass within the cargo compartment.

    • With high ambient temperatures and fully opened doors, a total loss of temperature controlled air within Cargo Compartment will take place in less than 12 Minutes.

    • TP-03 – Default = 3 Hours - Variable depending upon each departure airport rules.

    • Total transit and tarmac time incorporate container transfer by truck from Handling Agent facility, trucking, security access and delivery to high loader and transfer to Aircraft on Tarmac.

    • High loader transfer and loading Container within aircraft cargo hold - exposure to ambient temperature shall be considered for planning

    • Departure of aircraft - on schedule.

    • Delays airside not included.

    • TP-04 – Default = 8 Hours

    • Storage within forward or aft aircraft cargo hold apply.

    • Ambient temperature is stable and not exposed to external heat.

    • Actual ambient temperature ranges can be extracted from TCU Data Log files by calculating period from flight departure to flight arrival for each destination.

    • Default values used for Dry Ice calculation:

      • 12 deg. C for Winter season and

      • 20 deg. C for Summer season.

    • Late flight takeoff not considered.

    • TP-05 – Default = 4 Hours

    • Tarmac Operation at destination includes turn around time (TAT) from aircraft arrival at gate, offloading, transfer of Container by high loader from cargo hold to aircraft door, offloading and re-loading of catering trolleys, passenger arrival and aircraft take off.

    • Upon the opening of the Cargo Hold door, the hold temperature will increase due to the inflow of ambient air.

    • Example: Accra ambient 34 deg. C, cargo hold 20 deg.C prior to arrival, temperature exchange of 14 deg. C. after door being open.

    • Short and medium term airside storage on the Tarmac using an ULD Dolley or ULD truck will expose the Container to higher ambient temperature, rain and sunshine

    • TP-06 – Default = 8 Hours

    • Storage within forward or aft aircraft cargo hold apply.

    • Ambient temperature is stable and not exposed to external heat.

    • Default values used for Dry Ice calculation:

      • 12 deg. C for Winter season and

      • 20 deg. C for Summer season.

    • Temperature control may no be longer be required or available.

    • TP-07 – Default = 3 Hours - as per local airport rules and operations

    • Total transit and tarmac time incorporate container transfer from high loader at tarmac, truck from tarmac, trucking, security exit and delivery to Handling Agent facility.

    • Temperature control may no be longer be required or available

    • TP-08 – Default = 1 Hour

    • Upon receipt of Container at Handling Agent facility, removal of trolleys, boxes and ovens followed by internal and external cleaning.

    • Aft doors remain open during the process.

    • Exposure to ambient temperature

    • Total loss of any cold air within the cargo compartment will apply.

    • Temperature control may no be longer be required or available.

    • TP-09 - Default = None

    • External storage will result in Container being exposed to sunshine, rain, wind and ambient temperatures 24/7.

    • Please consider high ambient temperature impact of external storage - reference summer schedule, heat waves, exposure to sunshine, confined spaces, no air movements
