Vmommo, just out of interest, wich aircraft did you fly before? Remember that every aircraft has faults. But having said that I think pilots should give a lot more feedback to the manufacturers about ergonomic and human factors design issues. Even on the most modern aircraft there is still lots of work to do to make them more comfortable (read healthy) for pilots. I am suffering back problems partly due to bad quality airconditioning and seats on the BAe 146. I hope the A320 is a bit better. I don't fly it yet, but I have flown the sims (320 & 330) and loved the way they flew.
