                2.5.3     Other traffic
                It is not enough to use your vision to keep the plane level. You must also keep
                a close eye on other traffic.
                Make sure you are visible so that others can see you (light). If others know you
                are nearby, there is a greater chance that you will be seen.
                Therefore: submit position reports and turn on your transponder!
                Remember your sunglasses, they are indispensable in sunlight - even sunlight
                over snowy areas, where you risk becoming snow-blind due to too much light
                if you do not protect your eyes.
                2.5.3.1     Collision risk
                Two planes on a collision course:
                                                            If  the  relative  bearing  between  two
                                                            planes  remains  constant,  the  image  of
                                                            the other plane will appear stationary.
                                                            It will just grow in size.
                                                            Fast.
                And suddenly the risk of collision is imminent.
