Sagey,
I may have to clarify the facts from my previous post. The Yugoslav Air law stipulates that in order to get a valid type rating a candidate must complete at least 50 hours of line training on RPT routes in the aircraft for which the rating is sought. For example they do not accept an American type rating with zero time on it.
Furthermore, another rule says that if you are not a company employee and the line training is conducted the company must make sure that their F/O is present on board ie. in the jump seat.
So the USD45 you pay only serves to cover the cost of the company's F/O, who is on duty even though not logging any hours. I think that this is a very cheap option of time building. Put it this way, people do the same in the USA when hiring a twin in order to gain the hours.
