Which statement about the effect of windshield HI heat selection is true?

• A. The windshields are heated at the higher level only
• B. All cockpit windows are heated at the higher level
• C. Only the side windows are heated
• D. No window is heated

Answer: (A)

When you set windshield HI heat, the heating elements in the windshields are energized at the high level to prevent ice or fog and keep visibility clear. This setting applies specifically to the windshields, not to all cockpit windows, so they are heated at the higher level while other windows remain unheated. The idea is to provide maximum heating where visibility is most critical without unnecessary load on the system. So the statement that the windshields are heated at the higher level only accurately describes the effect of the HI heat selection.
