Training on the 737 is completely different to Long Haul..first of all, is actually training, and secondly, they don't treat F/o's and S/o's like children as they do in Long Haul..
How long since you last did a training course in Longhaul? Which fleet?
There's a bunch of excellent trainers out there (but sadly still a very few who perhaps are there for the wrong reason). Many of our best trainers began that role on the 767 which most agreed had a great training culture.
As a general rule, most of our Longhaul trainers have embraced the new training-emphasised cyclic matrix and carry that over to the line training environment very well.
…..and I haven't been a Trainer for 6 or 7 years.
