Flight spoiler purpose
Hello Internet aviation gurus,
I am presently sitting a type rating course for a FBW aircraft. The course material talks about the multi-purpose flight spoiler by mentioning that the purpose is to (1) Enhance roll control, (2) Reduce airspeed and (3) airbrake.
My question is what ever can be the difference between (2) and (3)???
Please speculate and enjoy trying to understand my english.
