During 1998, 

 116 aircraft sorties 

 were flown in 

 support of IIP. Of 

 these, 55 were 

 transit flights to St. 

 John's, 



Newfoundland, HP's 

 base of operations. 

 There were 55 ice 

 observation or 



patrol sorties 



conducted to locate 

 the south-western, 

 southern and 



southeastern limits 

 of icebergs. Six 



logistics flights were required to support 

 and maintain the patrol aircraft operational 

 status. Figure 8 shows HP's flight hour 

 usage for 1998. As indicated in Table 3, 



Ice Patrol schedules aerial reconnaissance 

 every other week rather than every week. 

 This is due, in part, to the ability of the 

 FLAR and SLAR RADAR combination on 

 the HC-130 to detect and differentiate
