Ford C,
MPL pilots will have plenty of single engine raw data training, probably more than you received.
Personally, I don't think the takeup rate for MPL is going to be very high. It includes a Type Rating and only those with half their brain tied behind their back will pay for a TR if a job is not attached. This effectively limits MPL in the UK to sponsored/tagged/mentored cadet programmes ala CTC, OAA, FTE, Cabair and only two of the four have TR facilities. Most self-sponsored students will continue with Modular or Integrated fATPL training. Some fear the Modulars will become marginalized, but I think that would only happen if airline recruiters came under mass hypnosis and accepted MPL en masse. That will never happen, so it's more likely that the MPL holders will be the marginalized ones for the first 5-10 years and these nine may be experiencing the fringe already.
