A surprisingly high percentage of Ryanair incidents seem to have involved the LHS being occupied by a trainer.
Whether this is due to the high number of trainers in the company, essential due to the fact that all new F/O's are Cadets and therefore higher than normal amounts of training are taking place in this company,excacerbated by the wildfire of expansion too , OR that very many LTC's are actually not "that" experienced, and are perhaps "encouraged" to bite off more than they can reasonably chew, whilst most of the old farts can't be bothered with the hassle for the meagre extra dosh on offer. . . well that certainly opens up an interesting line of discussion.
Would have to say, many of those who end up as trainers are not always the best qualified in the company, and don't always end up there for the best reasons.
