The use of the word "aviatrix" is correct, because it is the feminine equivalent of "aviator."
However, when I was flying for the Air Force, someone once used the term "aviators" to describe male pilots and "aviatrix's" to describe female pilots (as we used to do with the terms "actors" and "actresses").
It set off a PC firestorm.
Today, all version of language seemed to revert to the masculine. Every best actress winner I can remember in recent years will describe themselves as "an actor" and not "an actress."
Funny, until I read your comment, I didn’t realize the original article was about you and your crusade to teach us dimwits the proper use of language.
