I agree that even the new question is less than perfect. But it is certainly better than the one in the original post in this thread.
As I have said, some candidates might interpret it as an oil cooler coring problem and select the wrong answer. This problem could be eliminated quite simply by the CAA adding the words "oil temperature within normal in flight limits" or "ambient air temperature 20 degrees C" (or some similar temperature that would eliminate oil cooler coring).
But this thread illustrates two points of wider significance.
The first point is that problem questions will not be eliminated by waiting until the CAA stumble across them. Local PPL examiners need to look very carefully at all of the exam papers and make the CAA aware of all of the dubious questions. Candidates taking the exams should then make their local examiners aware of any dubious questions that appear in their exam papers.
The second point is that the Confuser is long out of date and contains some dubious questions that are not in the real exam papers. But people who passed their exams long ago when the Confuser was the only option and was probably more relevant, continue to advise new PPL Students to use the Confuser.
VW-Nutter started this thread because using the Confuser has done exactly what is says on the tin.... CONFUSED him/her.
