I would have thought that e learning for type courses was imperative. The costs of maintenance type training with some organisations, particularly the helicopter manufacturers, have risen to ludicrous levels. I doubt you will see much change out of £30,000 for a medium helicopter course. One provider charged £2000 for a 3 day conversion course.
The way forward would seem to be e learning for the theory and on site for the practical.
massive savings to be made. However what has become a cash cow for the manufacturers would evaporate so I don't expect any rush for change.
Take a current Bell 412 course 12 seats in the class about $12000 for the course spread over 4 weeks. £36, 000 dollars a week. To be fair to Bell they are probably the cheapest.
