The wiper switch is designed to allow for what action of the wiper blade?

• A. Landing light
• B. Trim switch
• C. Wiper
• D. Top right

Answer: (C)

The key idea here is understanding what the wiper switch does for the windshield. The wiper switch powers the wiper motor and selects how the blade moves, allowing it to sweep—wipe—across the windshield to clear rain or spray. That action directly describes what the wiper blade does, so the switch is designed to enable that wiping motion.

The other items aren’t related to windshield cleaning: a landing light provides illumination, a trim switch adjusts the aircraft’s trim, and “top right” isn’t a function related to the wipers.
