Place the vent control lever in the ______ position to direct warm air into the windshield and canopy side defog ducts.

The correct choice is to place the vent control lever in the CANOPY position to direct warm air into the windshield and canopy side defog ducts. When set to this position, the airflow will effectively target the areas that need defogging, ensuring that the pilot has a clear view out of the windshield and side windows, particularly in conditions where moisture may impede visibility.

The vent control system is designed to optimize airflow in the cockpit, and the CANOPY position specifically channels warm air to the critical areas that require defogging, enhancing safety and operational effectiveness during flight. This positioning helps to maintain a clear line of sight, which is essential for pilot awareness and overall safety in flight operations.
