201 – Pre-condition

Ref.:Description:
1.Introduction
1.1.Design: The RKN and RAP Skycooler are designed to function as Temperature Controlled Containers. Each unit has the capability to maintain a constant temperature range to provide an ideal environment within a sealed unit to effect the air transportation of temperature sensitive goods thus avoiding potential damaging fluctuations over extended periods of time. The required pre-determined internal temperature range is to be set by the user.
1.2.Ambient temperature; Reflects variable external temperatures during storage, pre-condition, loading, transfers to airport, loading and aircraft storage.
1.3.Cargo compartment temperature; Controlled by dry-ice supported by pre-conditioning.
1.4.Pre-conditioning of the cargo (catering); Pre-cooling of cargo is an essential step in the preparation of goods for transport.
2.Precondition of the Container
2.1.The internal temperature of the container should be the same as the intended set temperature or have reached the required pre-set temperature.
Pre-cooling the container will remove all present heat.
This should be completed in advance of the goods being loaded and can best be achieved by adhering to the following instructions:
2.2.Place the container in a cool warehouse with the door opened, so the inside of the container obtains the desired temperature.
If necessary, start the cooling system by loading dry-ice in the dry-ice box.

Load the container inside the warehouse and close the door before moving the container outside.
2.3.Store the container under a cover whenever possible.
2.4.Do not place the container in direct sunlight or in a heated area, when transporting cooled cargo.
3.Alternatives for pre-conditioning.
3.1.Area within chilled facility; Dedicated area with roller bed floor for easy management of containers/s. Aft doors shall remain open and secured, thereby, achieving an equal ambient/cargo compartment temperature (3.0 to 4.0 deg. C.) If permanent feature, pre-conditioning time is greatly reduced as the container never leaves the desired set temperature (4.0 deg. C).
3.2.External mobile chilled facility; Typical a reefer trailer with roller bed floor, with a Thermo King or Carrier refrigeration unit set to 3.0 deg. C for internal temperature. 3 Containers can be stored at any one-time, limited exposure to external ambient temperature with solid panels (door opening for container collection or delivery). Trailer can be moved onsite as required, also, be powered by diesel or electricity. Multiple trailers + transfer to ULD Trucks at any one time. Doors must be closed during handling.
3.3.Cold cargo storage; Dry-Ice compartment to be refilled with 100 + 20 Kgs. On an ongoing basis, new batteries every 72 Hours, thereby, mimicking or extending a typical movement. Labour and material intensive operation.
3.4.Only recommended in an emergency situation, whereby, 3.1. or 3.2 are not available.
4.Summary
4.1.It is a contractual condition and responsibility of British Airways PLC and its handling agent to operate Skycooler containers in compliance with the design and requirements specified within the Skycooler Operating manual.
5.In the event Inflight meals are declared not fit for human consumption due to excess temperature, upon return download TCU Data for QA analysis.
