This is like going from 200hrs approved course to rhs commercial jet. With the approved training it is perfectly acceptable nowdays and flogging around building 700 hours in a C152 is no longer necessary or appropriate. One could argue that the same should apply to Engineering today. I myself served a 4 year apprenticeship and most of my training is unnecessary in todays operations. A systems and type course with problem solving logic is all that is required today. If someone has the basic aptitude for the job then all that is required is sound understanding and being able to follow steps in a manual.
Provided the courses are approved and standards are met, I see no problem. I trust them.
