Abstract : Data on aircraft fleet service difficulties between 1988 and 1990 were used to estimate fire detector false alarms in the domestic commercial jet fleet. For Class C cargo compartments, data on fleet composition and utilization were used to establish false alarm rates using two levels of analytical detail. False alarms for engine nacelles, auxiliary power units, bleed air ducts, lavatories, wheel wells, and electrical and electronic bays are also considered. This treatment of false alarms is based on statisfical documentation of fleet discharge events for halon extinguishing agent bottles.
