Hey guys, passed the exam with only 70%.. I found this exam to be quite tough. There were a few tricky definition questions and such which you have to watch out for as usual.
There was a question on wake turbulence which went you are a light aircraft lined up on takeoff on runway 360 and a large aircraft has just taken off on runway 270. What is the time you have to wait before commencing take-off. I chose 3 minutes but it must of been wrong as it has appeared on the KDR.
If anyone has other idea it would be interesting to know.
Probably not a very good question. I think one needs a little more information to establish the context before a sensible answer can be developed. The answer could well vary from "not a concern" to "I'd wait quite a few minutes ..."

You could write a book on the information NOT provided with this question, making it impossible to give an sensible answer. For example where is the intersection of the two runways? What is the wind direction? See pages 19/20 of the publication below.
