FWIW I dont think the systems are hugely different from an arrow.
However, they will be looking for flying skills. If you have any speeds/power settings learn them inside out. I always found when learning checks that if I could say them really quick from memory then they would come out at normal speed under pressure of flying.
Remember fly the correct attitude with the correct power and youll be fine.
I dont think they will be looking for systems knowledge. Why ? Because they are not training you to fly a seneca. (Well they are - but not just that).
