TBM-Legend,
Correct, one techie, must have been a Second Officer, went sick in KLAX and the flight operated three pilot to NZAA, where the tech crew were replaced, and then on to YBBN.
According to this;
Great Circle Mapper
KLAX-NZAA 5652 nms ~ 11+12 (legal three pilot)
KLAX-NZAA-YBBN 6893 nms
&
KLAX-YBBN 6223 nms
So 670 nms the difference, or around an hour and a half extra flying.
Regards,
BH.
