To answer Genghis's previous note about women refusing to admit they could type - it's to save them extra work.
One woman I know (a trade unionist) would never LEARN to type because she said she would always be expected to take the minutes of meetings and deal with correspondence if she did (even though typing would save her time). I also know of a single man in a team of women who never had to take minutes and type them up because he was the only one who couldn't type.
(I'm sorry - slight thread creep)
To answer the original post, although a PPL, I've flown with some VERY experienced professional pilots and not one of them had a problem with female pilots. However, one did make a comment about women knowing left and right - but it was said as a statement of fact about a minor point, not a criticism. He felt women were no different to fly with than men.
