Wow....dissagreement in the answers here. Glad I don't have to sit this stuff again....here are my two cents (and I wouldn't pay a penny more for them).
1. A (technically you would violate rule 5. at some point though...)
2. C (looks like we all agree on that one....)
3. A
4. B
Where are these questions from? Thought JAA exams had a D in them as well?
