Our cadets arrive from Australia/NZ were they do a CPL or MPL with about 150hrs total time, they then do a conversion to the A320 & a full a/c & instrument rating for the RHS, they then complete another 80 sectors on the line with training capt, however most require extra sectors before they are given a final line check to the line, they are second officers by rank & pay, once on the line they have reduced x/w & increased vis/cloud base min, so yes they are wearing the rank of an SO however doing the work of an FO, as you can see this greatly increases the workload for line capt, especially this time of year with TS, typhoons & wind-shear.
