Splat re Type Ratings -
Tried to send PM but system failed. In essense a number of companies or TRTO organisations over the years have 'offered' type ratings, see past issues of 'Flight' for examples. Ive been in aviation 18yrs and that was my source of info when unemployed, (plus some personal contacts).
A rating without line experience isnt a huge amount of good, most companies like to do their own training and a self funded rating is a huge risk! I took my advice when unemployed 9yrs ago from the 'unemployed pilots job centre' at the gatwick jobcentre. The advice then was dont do a rating, I didnt, and Ive never regretted that. If they still exist a visit to their gatwick office might be a good idea, at least the advice would be free free!
I hope this is of some help
