safety critical risks;

                  (b) Respects, under non-fault and fault conditions, all the appropriate performance requirements specified elsewhere in this Regulation; and,

                  (c) Was developed according to the development process/method declared by the manufacturer.

              3.1.1. Documentation shall be made available in two parts:

                  (a) The formal documentation package for the approval, containing the material listed in paragraph 3. (with the exception of that of paragraph 3.4.4.) which shall be supplied to the Technical Service at the time of submission of the type approval application. This documentation package shall be used by the Technical Service as the basic reference for the verification process set out in paragraph 4. of this annex. The Technical Service shall ensure that this documentation package remains available for a period determined in agreement with the Approval Authority. This period shall be at least 10 years counted from the time when production of the vehicle is definitely discontinued.

                  (b) Additional material and analysis data of paragraph 3.4.4. which shall be retained by the manufacturer, but made open for inspection at the time of type approval. The manufacturer shall ensure that this material and analysis data remains available for a period of 10 years counted from the time when production of the vehicle is definitely discontinued.

              3.2. Description of the functions of "The System"

              A description shall be provided which gives a simple explanation of all the control functions of "The System" and the methods employed to achieve the objectives, including a statement of the mechanism(s) by which control is exercised.

               Any described function that can be over-ridden shall be identified and a further description of the changed rationale of the function's operation provided.

              3.2.1. A list of all input and sensed variables shall be provided and the working range of these defined.

              3.2.2. A list of all output variables which are controlled by "The System" shall be provided and an indication given, in each case, of whether the control is direct or via another vehicle system. The range of control (paragraph 2.8.) exercised on each such variable shall be defined.

              3.2.3. Limits defining the boundaries of functional operation (paragraph 2.9.) shall be stated where appropriate to system performance.

              3.3. System layout and schematics

              3.3.1. Inventory of components.

               A list shall be provided, collating all the units of "The System" and mentioning the other vehicle systems which are needed to achieve the control function in question.

               An outline schematic showing these units in combination, shall be provided with both the equipment distribution and the interconnections made clear.

              3.3.2. Functions of the units

               The function of each unit of "The System" shall be outlined and the signals linking it with other units or with other vehicle systems shall be shown.
