All of our courses are more or less obligatory to perform sometime during your active flying career. Except for Frank Abagnale Jr, well, just kidding - you know what happened. 😉
The ultimate decision on what topics you have to perform lies with your training manager and/or local Civil Aviation Authority. Get in touch with them for the latest updates about what courses you need to do.
