Caller?
 

Hi! I'm a newbi to IMAC and I'm doing the basic course this summer, but I don't exactly know what a caller is for, and I don't know if they need experience or not. Please share your expertise. Thanks

A caller watches for other planes, (so as to avoid a midair colision) he can coch your manuvers, he can call the next maunver for you, really helpful in the heat of battle so to speek.
Your caller is your best friend.
