I looked through the annual report of the IAA also and what struck me was the focus on economics
Might explain why the cost of an IAA ATPL is 100's% more than UK or NL. The same goes for TRI & TRE revalidation's. They charge extortionate amounts. When challenged on this the IAA said they were tasked with being financially self sustaining, and that it was normal for airlines to pay these costs not the individual pilot. Extraordinary!
