Is the SN3308s rear-projection display readable in direct sunlight?
I worried about that situation myself, particularly because I’m flying a low-wing airplane. The answer is that bright sunlight at certain angles does degrade the contrast of the display, but certainly not enough to make the instrument difficult to read. The worst case seems to be flying with the sun at the eight o’clock position (i.e., over the pilot’s left shoulder). That’s the only situation I’ve encountered in which loss of contrast was noticeable, and even then it was definitely not a problem. Under all other conditions, the display offers all the contrast you could want. At night or in the soup, of course, it’s just breathtaking.
