FIFO... low utilization!!! Just look at the Qf KA operation...it is far from low utilization...Qf Perth 737 base not expanding anymore since Joyce bought Network...!! (even transfered 3 F/O's from Per to Bne without replacing them!) They will probably take over some of Qf's W.A & Qld FIFO operations and should be able to get good use out of the 737NG's. ADSB is good but the Qf NG's have up to .1nm Rnp for approach capability. The mines are demanding this latest technology to change over their workforce so as not to affect their production!
