In which direction should the speed brake switch be moved to lower the speed brake?

• A. Forward
• B. Aft
• C. Downward
• D. Upward

Answer: (B)

To lower the speed brake, the switch must be moved aft, which is a common design in aircraft controls. This action is often intuitive as moving controls in the direction of the intended function is standard in aviation ergonomics. When the switch is moved aft, it signifies a command to retract or lower the speed brake, allowing the aircraft to resume normal flight conditions without drag. Understanding this movement is crucial for pilots and ground crew, ensuring proper aircraft operation and performance during various phases of flight.
