CG Wide 1) 3 searches / day = ~ 1000 / yr 2) 3 CG Wide 1) 3 searches / day = ~ 1000 / yr 2) 3 persons lost / day = ~ 1000 / yr 3) Costs $10 k/hr to search • $10 k/hr x ~1000 x ~ 3 hr = ~ $30 M 4) Value of Statistical Life = $3 M • 1000 x $3 M = ~ $3 B

CG Wide 1) Assume 100 persons involved / yr with sub-optimal search areas 2) CG Wide 1) Assume 100 persons involved / yr with sub-optimal search areas 2) Assume 22% POS now “typical” 3) 22 save/100 vs. 48/100 vs. 67/100 4) Save 26 to 45 additional persons / yr • ($ 78 M – $135 M VSL)

Search & Rescue Problem • Create a SAR case when alerted • Gather data, Search & Rescue Problem • Create a SAR case when alerted • Gather data, estimate uncertainties • Use model to determine search area • Estimate resource availability and capability • Plan the next search • Promulgate the search plan • Perform the search plan • Evaluate the completed search • Repeat above until survivors are found and rescued
