Accomplishment of all towing procedures shall be followed in exact step-by-step CHECKLIST sequence to prevent damage to equipment or injury to personnel.

• A. Random order
• B. Approximate steps
• C. Exact step-by-step CHECKLIST sequence
• D. No sequence required

Answer: (C)

The main concept is that towing operations rely on a precise, verified sequence coordinated by a checklist to manage interdependent safety actions and protect equipment and personnel. Following an exact step-by-step order ensures every necessary action is performed in the right context, with the proper prerequisites in place. For example, securing the towbar, installing safety devices, verifying clearance, and confirming communication with the cockpit or flight crew are all steps that depend on earlier actions being completed correctly. If any step is skipped or done out of order, a later action may be ineffective or unsafe, leading to equipment damage or injury.

Using a random order introduces the risk of missing critical steps or performing them under inappropriate conditions. Approximating steps invites drift from the required safety checks and can leave hazards unaddressed. Saying no sequence is required removes the structured controls that prevent mistakes in high-risk ground operations. A standardized checklist sequence provides consistency, accountability, and a documented record that the operation was performed safely and thoroughly.
