I am starting a new job early next year on the A320 and have never flown an Airbus before. I'd like to do some reading to get a head start on the training, can anyone recommend any good books? Note I'm looking for books with technical detail of aircraft systems and their functioning and operating and performance data. Please don't recommend books with historical anecdotes and info for plane spotters (not that I have any problem with spotters, of course).
