Aircraft Flight by Barnard and Philpott. Published by Longman Scientific and Technical, ISBN 0-582-00338-5
By far the best IMHO. I don't know if it's appropriate for the JAR ATPL syllabus, but it was ideal for someone with a small brain doing his CFS A2 in 1993.
Update - a quick check on Amazon shows it's out of print, but they have some second hand copies staring at 63GBP.
