ATPL Online systems exam
 

Hey everyone. I am studying for this exam and I am going through the syllabus and ATPL online New Zealand. There was recently a syllabus update and I am finding a few things not covered very well in the online material. One of the syllabus items is "explain swept wing pitching moments at subsonic and transonic speeds." A seemingly easy question but I just can't think what they are asking. If anyone recalls this from when they did the exam your explanation would be much appreciated:)
