The purpose of this study was to evaluate the acceptability of the 'CF One Man Life Raft' and various alternatives for sea-environmental suitability and aircrew survivability in all threatres of CF 188 oprations. Of the six life rafts studied, the LRU-23/P was the most suited for replacement. The life rafts were evaluated against the following criteria: buoyancy, stability, survivability (thermal resistance), vacuum packed volume, and vacuum packed weight. The study showed that the thermal resistance was at least ten times greater for life rafts with inflatable floors (0.60 Clo - 0.71 Clo) when compared to those with non-inflatable floors (0.06 Clo)). This property greatly increases the chance for aircrew survival. It was also noted that life rafts made wiht polyurethane-coated fabric and RF-welded constructon were lighter and less bulky than those made with older materials and glued construction. Hence, the LRU-23/P, possessing all the above characteristics, was recommended as a viable off-the-shelf replacement solution. To further reduce packed volume and weight, but still not jeopardizing aircrew survivability, a recommendation was made to consider a hybrid of the LRU-23/P - inflatable bottom with non-inflatable canopy.
