Current projects include:

 

Integrated Fire Protection Systems
Customer: Transport Canada

Project Objective: To determine the feasibility, practicality, and possible improvements to passenger safety that are likely to result from the implementation of ‘integrated’ fire protection systems (including, cabin/cargo water mist systems, nitrogen inerting systems, OBIGGS/OBOGS, etc.)

  Studies on Thermal/Acoustic Insulation Fire Risk Reduction - development of a Mitigation methodology
Customer: Transport Canada

Project Objective: To investigate the flammability performance of hidden materials, particularly thermal/acoustic insulation, and potential means by which pertinent threats can be quantified and mitigated

This research is in support of the Materials Fire Test Working Group activities.

 

 

Training Needs Analysis of Cabin Crew Training Practices and Standards with respect to the management of Fire Incidents

Customer: UK Civil Aviation Authority

Project Objective: To evaluate current and possible future issues, and identify potential improvements in existing fire training in order to ensure that cabin crews have the most appropriate training and procedures to match current and likely fire threats.

Training courses in System Safety Assessment Techniques and Applied Safety Assessment

Currently being presented to: the European Aviation Safety Agency and STM A.Ş Turkey (in conjunction with Cranfield University)

  An evaluation of technologies for aircraft cabin firefighting and improving occupant survivability during post-crash fires
Customer: UK Civil Aviation Authority

Project Objective: This study is evaluating means that might be used by RFFS units for sustaining a survivable environment in an aircraft cabin and performing cabin firefighting during a post-crash fire.

 

 

Further studies on automatically-disposable hatches (ADH) in order to determine some of the issues that might need to be considered in the development of pertinent regulations
Customer: Transport Canada

Project Objective: Earlier phases of this Project assessed the benefit of using automatically-disposable hatches at overwing exits. This Study is currently being used by the Harmonized Rulemaking Process being conducted by EASA in co-operation with Transport Canada and the FAA. The intention during this phase of the Project is to support this activity further by providing data and analysis to support and justify legislative requirements.
