5.3 Safety Priority
5.3.1 An ATM Service Provider shall, as an integral part of the management of the ATM service, have in place a SMS which ensures that the achievement of satisfactory safety in ATM shall be afforded the highest priority over commercial, environmental or social pressures (867).
NOTE: See also Part A, paragraph 6, for SMS regulatory arrangements.
5.3.2 Rationale: The safety management system should clearly address and resist business pressures that challenge the safety of the provision of the service (868). Conversely, the safety management system should ensure that safety is not used to support commercial, financial, environmental etc. decisions inappropriately, which have little real safety significance (869). If the term 'safety' is abused in this way the safety management system cannot be focused on controlling the real risks.
5.4 Safety Objective of the ATM Service
An ATM Service Provider shall, as an integral part of the management of the ATM service, have in place a SMS which ensures that while providing an ATM service, the principal safety objective is to minimise the ATM contribution to the risk of an aircraft accident as far as is reasonably practicable (870).
NOTE: Where risk is concerned there is no such thing as absolute safety. 'As far as is reasonably practicable' means that risk in a particular activity can be balanced against the time, cost and difficulty of taking measures to avoid the risk. The greater the risk to safety, the more likely it is that it is reasonable to go to substantial effort to reduce it. It is implicit, therefore, that hazards have to be identified and the risk assessed before a judgment can be made upon their tolerability.
5.5 Competency
5.5.1 Within the operation of the SMS, the Service Provider shall ensure that staff are adequately trained, motivated and competent for the job they are required to do, in addition to being properly licensed if so required (871).
5.5.2 Rationale: Staff competence is fundamental to safety.
5.5.3 Requirements for Engineering and Technical Personnel Undertaking Operational Safety Related Tasks (derived from ESSAR 5).
NOTE: ANSPs are also required to comply with SES Common Requirements, Annex 11, paragraph 3.3, Safety requirements for engineering and technical personnel undertaking operational safety related tasks.
5.5.3.1 Introduction
a) Definition
For the purposes of these requirements, engineering and technical personnel undertaking operational safety related tasks are personnel who operate and maintain ATM equipment approved for operational use.
b) Rationale
The competence of ATM personnel and, where applicable, their satisfaction of medical requirements, are fundamental elements of safety achievement, and therefore of safety management, in the provision of ATM services. The application of EUROCONTROL safety requirements in this area aims to establish harmonised minimum levels of competence and proficiency for staff having specific ATM safety responsibilities. ‘Competence’ is taken to mean possession of the required level of knowledge, skills, experience and, where required, proficiency in English, to permit the safe and efficient provision of ATM services.
c) Applicability
These requirements shall apply to ATS providers and to all engineering and technical personnel as defined above who are responsible for tasks which, within provision of an ATM service, are identified as safety related.
d) Safety Objective
The overall safety objective is to ensure the competence and, where applicable, the satisfaction of medical requirements, of engineering and technical personnel responsible for safety related tasks within the provision of ATM services.
