## Cargo Compartment Water Mist/Inerting System Concept

- Halon replacement fire suppression system utilising NEA from OBIGGS and a water mist system has been shown to pass the Minimum Performance Standard FAA DOT/FAA/AR-TN05/20

- ICAO: *“Industry and the scientific community need to redouble their efforts to find suitable replacement agents for halon in civil aircraft. In particular, a halon replacement for cargo compartments is critical.”*

## Cargo Compartment Water Mist/Inerting System –Primary Issues resulting from Transport Canada research

- Cargo Compartment Water Mist/Inerting System –Primary Issues resulting from Transport Canada research

- The system has advantages over the current Halon systems including:
-  Environmentally friendly
-  Not time limited – operational throughout the flight but only available on ground whilst engines are running
- To date a total of 11 issues have been identified requiring resolution in order to develop the system further

- Cabin Water Mist SystemConcept

## Cabin Water Mist System Concept

- Cabin Water Mist Systems may be cost beneficial as part of an Integrated Fire protection System.  They will complement fuselage burnthrough protection in accidents where there are fuselage breaks

- AAIB Recommendation resulting from the Manchester B737 Accident in 1985: “Onboard water spray/mist fire extinguishing systems having the capability of operating both from on-board water and from tender-fed water should be developed as a matter of urgency and introduced at the earliest opportunity on all commercial passenger carrying aircraft.”

- Cabin Water Mist System –Primary Issues resulting from Transport Canada research

- To date a total of 12 issues have been identified requiring resolution in order to develop the system further
-  Perhaps the most important of which is the need to develop a Minimum Performance Standard for the system

**HIDDEN AREAS FIRE SUPPRESSION SYSTEM **

## Hidden Areas Fire Suppression System Concept

- Distributing NEA from OBIGGS to extinguish fires in hidden areas

## Hidden Areas Fire Suppression System Concept

- Primary issue: containing inert condition in the fire area with a high airflow condition
- FAA ongoing research

## Hidden Areas Fire Suppression SystemProject Achievements
