I did my brief on the differences between aircraft and auto engines and the reasons why. I just thought it might make a change for the examiner, he seemed to find it interesting. Its the ability to 'brief' that was to be tested, I dont even think it has to be aviation orientated.
As far as plagerism goes we're not trying to reinvent the wheel here just pass on some tried and tested facts which can be adapted to suit you and/or the student,
relax folks it makes things so much more enjoyable.
