Flightleader
We always seem to be able to carry the pax and the cargo on the Tahiti-LAX sector in the 763 (about 8 1/2 hrs). We get hit on payload on the Fiji - Lax sector (closer to 11 1/2 hrs) but in both cases the single engine depressurised fuel requirement is more punishing than the ETOPS fuel.
In the last part of the flight we are using HNL and LAX as the enroute alternates.
In both cases a large deviatition north of the great circle track is required to stay within the 180mins range circles.
