So will the MPL graduates. All MPL courses currently running include solo flight and recovery/upset training, as stipulated by the mentoring airlines

But surely it's such a small amount of solo time that it makes no difference which way they train. I wouldn't suggest they make bad captains, I wouldn't know. But it doesn't seem unreasonable to think that they take a bit more time to pick up the "non flying" skills vs. someone with the same hours on type but another 300-500 hours of real cross country flying.
