But of FO's do not want to upgrade they need DEC's to fill the left seats to keep the fleet flying. As the sim can only be used for one purpose in each session... cadets may have to wait until LHS is sorted out.
Some signs of improvements are visible, but some of these small steps not generally regarded by many as improvements but only by some. They also are not having the effect of the way forward the company would like to have seen.
Next options available in short term are DEC's. When that has been exploited the only way to show you mean better staffing levels and retention is to put the ££/€€ where the mouth is, to correct the imbalance created in the last decade by reduced pay in comparison to competition airlines who got for instance inflation correction (at least) top their salary earned. So simply improve these financial conditions to existing crews so they won't want to leave and retain them to train the next cadets.
