3. Systematic safety
total system approach is based on the fact that the aviation system components – products, operators, crews, aerodromes, ATM, ANS, on the ground or in the air - are part of a single network

4. Prescriptive regulation
Binding standards set. Inspections check compliance.
Pro – easy to understand
Con – absolute and inflexible
Example: ICAO Annex 14
Information concerning the level of protection provided at an aerodrome for aircraft rescue and fire fighting purposes shall be made available.

5. Objective based regulation
Objective, goal or target is set. Advisory material provided. Demonstrations needed.
Pro – flexibility. Different solutions possible
Con – continued achievement not guaranteed
Example: Large Aeroplane CS
(b) The aeroplane systems and associated components, considered separately and in relation to other systems, must be designed so that -
(1) Any catastrophic failure condition
(i) is extremely improbable; ……………

6. Performance based regulation
A measurable level of performance is periodically monitored and reviewed. Performance is established, maintained or improved.
Pro – continuous monitoring, transparency and mechanism for improvement
Con - requires intelligent definition and application
Example: Commission Regulation (EU) 691/2010 on the performance scheme for air navigation services and network functions defines safety key performance indicators
*requires intelligent definition and application because it drives people’s behaviour

Why change?
Need for change
Growth in a dynamic industry;
Complexity, interconnection and interactivity and
Lessons learned and commitment to continuous improvement
Some prescription needed;
Objectives good for design requirements and

8. Worldwide Runway Excursions
The slide contains the global rates for runway excursion accidents per 1 million flights in commercial air transport operations, above 2250kg MTOM between 2000 and It is a rate based on estimates of aircraft movements per State. Some countries have reported no runway excursion accident and are shown in grey.
Colour codes:
Green: up to 1 excursion per million departures
Light Green above 1 and up to 2 runway excursions per 1 million flights
Yellow: 2-3
Orange: 3-4
Red: 4 and above

10. EASP Strategy Programme Plan
The European Safety Strategy is a set of policies and objectives which are laid down by the European Commission
Programme
The European Aviation Safety Programme is an integrated set of regulations and activities aimed at improving safety
Plan
The European Aviation Safety Plan is a high level safety issues assessment and related action plan
