I'm currently studying this subject, and am very glad I found this thread.
I haven't got all the way through yet, I'm currently doing the CP and PNR examples, and was wondering if anyone could answer a question for me (actually, I'll probably end up asking a lot of questions, but we'll start with this one!).
For some questions, I've noticed they don't bother putting in the crosswind-caused headwind component (probably because it isn't very significant), but at other times they do (even if it's just 2 kt, which is what I've worked it out to be at times when they don't include it). So my question is - is there a guideline to follow to figure out if the crosswind-caused headwind component is big enough to mention on the flightplan (and therefore adjust the groundspeed)?
Also, just as a side question, I followed what people said to expect for question topics, and figure that there'll be a few CP and PNR questions in the depressurised and 1 engine in-op configurations, but are questions on gear down scenarios and inoperative yaw damper common?
Thanks!
