I can find no reference to R-LOC anywhere. Emailed a few buddies who between them have over 100,000 hours. No joy. Has anyone else ever heard the well-documented term R-LOC? Anyone? Anyone at all?
I've just had a thought - its a Microsoft FS term isn't it?
Anyway, you asked for info about light sport aircraft but don't seem to even be able to grasp that although a ULA FK-12 and LSA FK-12 look the same, they do not fly the same.
Look up the term wing-loading and try and work out why if one airplane weighs 472.5kg and the other identical looking one weighs 600kg they fly differently.
