is the 'anthropomorphic filter' bugged ?

In manual, page 10: Anthropomorphic Control. This option limits the amount of things you can do at one time to realistic proportions, usually to no more than two things at once. As a pilot has only two hands, and as most Battle of Britain era planes did not have HOTAS-style controls with important buttons always a flick
away, moving the throttle and stick will usually mean having no hands to move a flap lever or vice versa.

So, this should be that way. Turn it off if you have problems with it or do things slower.
