I don't think the A350 EFF was where the training issues were coming from. I suspect it was more of a data location and management issue...exacerbated by long-time Whale pilots who had only flown Boeing and never been through an AQP Initial Qual program showing up to a completely different training program than they had ever experienced (I e., self-taught and a morning of systems refresher before the eSV, not a week of classroom instruction before an FAA oral as used to be the case) and jumping into all of that to learn the most modern Airbus product out there.

That said, I suspect 350 pilots would tell you their EFF is much better than the Mission+ product.
