ABSTRACT:
An objective lens is mounted to the lower exterior portion of a canopy to focus sunlight into an attached fiber optic bundle. The bundle then carries the light a relatively short distance to an instrument panel where it may be disbursed at a diffuser for projection through an LCD. The readability of the display becomes enhanced when sunlight causes the greatest visual interference with a pilot's vision.
