As it happens, I was just reading the test standards for the FAA IR. It mentions that during the test, the examiner will cause a 'distraction' to assess your ability to concentrate on flying, and multi-task. I'm very curious as to what kind of things they might get up to - anyone have any examples?
Mine did this, several times! Starting asking my thoughts on the War in Iraq, Women,etc. Ended up telling him I was busy at the mo, which turned out to be the response he was looking for!
