Thanks for your comments, I will try to justify my logic. The way the survey is structured means that each of the statements must be biased one way or another, otherwise people couldn't agree or disagree with them. Since people can freely agree or disagree with each statement, I think its just about as objective as a survey can realistically get, although i grant that complete objectivity is always virtually impossible.

I could have equally made the statements biased in the opposite sense, and would then have had people saying I was implying that pilots haven't lost their authority! If you disagree or strongly disagree with any statement then please put your tick in the appropriate box. I am not 'hoping' for a certain trend to come out, but will duly achnowledge any trends, be they in agreement or disagreement with the survey statements.

I hope this helps to explain things a bit. For anyone who is uncertain, I can assure you that I will treat the results with as much objectivity as possible. Indeed some of the emerging trends do disagree with certain statements while others agree, and this will all be given equal credence.
