DEFINITION:

A fire protection (FP) system in an aircraft includes passive and active FP means. Passive FP is achieved by using fireproof, or fire-resistant, materials. Active FP systems comprise smoke, fire and overheat detectors with indicators, fire suppression devices and a management control sub-system.

SUBDOMAINS:

  1. Passive protection – fireblocking layer on materials (e.g. cabin seats), fire-resistant fittings, floor coverings and non-structural applications
  2. Detection systems – smoke (back-scattering, optical attenuation), fire (gas sensing, near IR, IR), overheat, hot air leakage
  3. Fire suppression – halon, watermist/nitrogen flooding,   environmental impact, piping, valves, on-board inert gas generation systems, hand-held extinguishing systems
  4. Control systems – maintenance panels, cockpit display panels, visualisation of system status, audible alerts, design (zonal configuration, redundancy, reliability, systems research, analysis of operational incidents), BITE
