Dual fleet is a trial, and one that’s been tried before several times. 78 winter, 73 Summer. At the minute, the training department can’t keep people
in check on one type never mind two. It’s a bright idea to keep costs down and reduce the Winter/Summer imbalance especially on the 73 fleet. The thought of employing staff to actually administer it or promoting trainers to deliver it it won’t of crossed anyone’s mind. Ill be amazed if it actually happens.
