Yr Right, Conartist or whatever pseudonym your going under today, your arrogance is quite clear. Here is a question for you: Have you done an APS course?
It is OK I already know the answer, so here is another: if you haven’t done a course, how it it you profess to know what they teach?
I for one actually like your input here in this forum but your know all arrogance and poor grasp of the English launguage are disappointing. It is after all a pilots forum, not an engineers “I know everything” wonderwall.
