(2) P = T M M D D 2.8.2.5 With regard to integrity, since the probability of occurrence of an unsafe failure within the monitoring or control equipment is extremely remote, to establish the required integrity level with a high degree of confidence would necessitate an evaluation period many times that needed to establish the equipment MTBF. Such a protracted period is unacceptable and therefore the required integrity level can only be predicted by rigorous design analysis of the equipment. 23/11/06 ATT C-32 2007/70/II. szám Attac ment C Annex 10 — Aeronautical Communications 2.8.2.6 The MTBF and continuity of service of equipment is governed by basic construction and operating environment. Equipment design should employ the most suitable engineering techniques, materials and components, and rigorous inspection should be applied during manufacture. It is essential to ensure that equipment is operated within the environmental conditions specified by the manufacturer. The manufacturer is required to provide the details of the design to enable the MTBF and continuity of service to be calculated. It is expected that the equipment MTBF is confirmed by evaluation in an operational environment to take account of the impact of operational factors, i.e. airport environment, inclement weather conditions, power availability, quality and frequency of maintenance. For integrity and continuity of service Levels 2, 3 or 4 the evaluation period should be sufficient to determine achievement of the required level with a high degree of confidence. The following considerations apply:
