under tuition last friday I had an interesting moment with an icarus. I heard the pilot of the icarus declaring his location and intention to join at base, just as I was turning downwind.
both myself and the instructor spent a few seconds looking out for him but we couldn't see a thing. within a few seconds I spotted the aircraft - before my instructor - at circuit height on what looked like a head-on collision course.
we both banked right. I'm not sure how close we got but it felt pretty close to me. I would guesstimate at < 500 metres before I 'chickened' (first!).
apart from that - great lesson
