If you trully think that there is equality in this industry you are living in dream world!
There are many employers out there who employ female pilots and one of their reasons (probably not the most important) is that in a tourism operation they feel that customers respond positively to a female pilot - and I am generalising here. Your industry in the UK is much different to that here in Australia for the smaller aircraft and discrimiation happens - we live with it and it is a pleasant surprise to see a little swing. There is probably a very good reason for wanting a female pilot and without knowing it I think you should all just calm down.
You are all getting your knickers in a twist because a job add actually had the balls to say what they really wanted rather than just letting a heap of applicants apply who's resumes they would probably use for toilet paper on their 207ft reesearch vessel!
