I believe I have found a few errors


CASR 61.875
For subregulation (1), the flight or simulated flight must:
a) have a duration of at least one hour; AND
b) include at least one instrument approach

You can't claim the 17 hours prior flying in OZY as the 1 hour needed for the CASR, the flight time and approach have to happen in the same flight



AIP GEN 3.3-7 4.6
Says you need to have the 5NM buffer, so I'm a bit confused why you can leave the buffer out if the question doesn't say you need it?
The Bob Tait IREX book even adds the 5nm in both examples.

Thanks for your feed-back. You are correct, Question 18 should have made it clear that the one hour instrument time must include the instrument approach. They are not separate requirements. I have made the necessary changes to the question.

In question 27, the wording of the question says that the tolerance area MUST INCLUDE a circle centered on Bravo, when you add the 5nm buffer that doesn't change the radius of the semicircle itself. Just trying to be obtuse like CASA!
