I just did the exam today and got a question similar, something like:
Q: High level jets flow from West to east, you are flying south over aust at FL 300 and the oat is steadily decreasing, where are you in relation to the jetstream?
A: Above/Just below/Significantly below/In the Jet
Put down just below and didnt come up on my KDR...
Some of the icing questions are so absurd.. had one like:
Q: You are flying in light/mod turbulence through a thick altostratus cloud at -3 OAT... what type of ice is most likely?
A: Rime/a combination of rime and clear/clear/none...
I put combination of rime and clear but got icing on my KDR
And another one
Q: Which situation would lead to the most rapid build up of ice?
A: Flying through cumulus @ -5deg/Flying through cumulus @ -15deg/stupid answer/stupid answer
I put flying through at -15 because rime ice forms more "rapidly" than clear ice but got icing on my KDR again
