A few practical suggestions.
(1) Tack, that is if you have to go due west, plan a route initially NW, then due South. Takes longer, but avoids flying directly into the sun.
(2) Fly low and slow, hard work but you've a better view down there and less other traffic.
(3) Get a RAS (normally only available if you have a transponder working).
(4) Make sure the windscreen is clean before you start.
(5) Don't wear sunglasses in anything like a flexwing which will stop you taking them off if you fly through sunset. (I made this mistake once, and although legally I didn't use my night rating, I certainly used the training!).
