This prevents fogging of the panels. The for-
ward windshields operate at higher tempera-
tures to provide anti-icing.
The forward windshields use 200-volt AC
power for anti-icing and defogging, while 115-
volt AC power provides defogging of the side
windows. (See Figure 10-9.) The windshield
and side windows are powered from three
separate AC buses. AC bus 1 supplies the left
windshield and the AC essential bus supplies
the left side window; AC bus 2 supplies the
right windshield and the right side window.
Temperature in the left and right panels is
controlled by two independent anti-icing con-
trollers. In addition, the temperature in the
windshield and side windows is controlled by
separate circuits within the controllers.
The controllers receive temperature signals
from sensors embedded in each panel. A sec-
ond sensor is provided in each panel as a spare.
