System Safety Training

R.G.W. Cherry & Associates Limited is a U.K. consultancy company formed in 1992 from widely experienced Aeronautical Engineers.  The company has achieved an excellent reputation for the quality of work delivered to airworthiness authorities, academic bodies, aircraft manufacturers, equipment suppliers and aircraft operators. In particular, it has also carried out safety research studies with the U.K. Civil Aviation Authority, the U.S. Federal Aviation Administration, Transport Canada and the European Aviation Safety Agency.

The company has provided System Safety Assessment training courses to industry for a number of years.  We provide bespoke 25.1309 training at the customer’s facilities. The courses specifically address the techniques involved in carrying out a System Safety Assessment.  It has a large emphasis on delegate participation in order that a full understanding is achieved of how to use the techniques. The subjects addressed include: Functional Hazard Assessment, Zonal Safety Analysis, Fault Tree Analysis, Enhanced Fault Tree Analysis and Failure Mode and Effect Analysis.

The course is based on the safety assessment of Large Transport Aeroplanes, however since the emphasis of the course is based on the concepts of safety analysis it will be appropriate to other aircraft categories and other industries.

Courses offered

Safety Assessment of Aircraft Systems – 5 day course

The course is aimed at engineers and managers that may be involved directly or indirectly with the System Safety Assessment process, although it is formulated on the assumption that the participants have had no previous formal instruction on safety analysis techniques and processes. It will, therefore, be of interest to both the experienced practitioner and the novice.

The objectives of the course are to give participants:

  • An understanding of the methodology and analysis techniques for carrying out System Safety Assessments, including Functional Hazard Assessment, Zonal Safety Analysis, Fault Tree Analysis, Enhanced Fault Tree Analysis and Failure Mode and Effect Analysis.
  • Familiarity with the mathematics and statistical distributions involved in the process.
  • A knowledge of some of the more common errors encountered in analysing aircraft systems.
  • An understanding of the interaction between the safety analysis process and systems architecture, and how the results of the safety analysis affect the maintenance and operation of transport aircraft.

The course is typically held over five days and constitutes:

  • Lectures with question periods. Participants are encouraged to ask questions during the lectures to ensure a common understanding.
  • Tutorials and exercises where participants will be shown how to solve problems and will have the opportunity to work on problems themselves. A full set of coloured printed course notes is provided to all participants and on successful completion a course certificate.
  • Coffee and tea are provided during breaks and a light lunch at mid-day.
  • A course dinner is provided on Thursday evening.
