One thing that puzzled me a few years ago, when I did my sim check, was whether I reacted correctly to the trainer trying to put me off my nav. During the complex departure he started asking questions such as "speedbird 1, requesting time estimate for MID". Told hime to standby, so he asked again, and told him to standby again (we were just about to intercept a radial). Once established on the radial, I gave him the time estimate.
In real life, that's what I would do. But since I didn't get through and otherwise flew to IR standards, I always wondered whether he thought I lacked spare capacity...
