What is the last step in the engine startup process?

• A. Place generator field switch OFF
• B. Remove reverser
• C. Confirm air brake system is charged and operative before releasing the hand brake
• D. Set independent

Answer: (C)

In the startup sequence, the final safety check is to confirm the air brake system is charged and operative before releasing the hand brake. The air brake system relies on compressed air to apply and release brakes; if the pressure isn’t up to spec, the brakes may not work when you start moving, or they may fail to hold, leading to an uncontrolled motion. Once you’ve verified the air system is charged, you can safely release the hand brake and proceed. The other steps—energizing the generator field, setting the reverser, or configuring the independent brake—are completed earlier to prepare the machine, but the last step that ensures safe movement is confirming the air brake readiness.
