Which of the following is NOT a recommended safety measure during aircraft towing?

The recommended safety measures during aircraft towing are essential to prevent accidents and ensure the safe handling of aircraft. Among the listed choices, ensuring the nose steering wheel pin is installed is vital for proper towing operations. This pin prevents the nose wheel from turning during towing, which could lead to an uncontrolled situation. Therefore, the installation of the nose steering wheel pin is indeed a critical safety measure.

In contrast, while actions like using adequate chocks, checking the TOW STATUS MODE indicator, and maintaining a slight angle during movement are all safety practices, the choice highlighted as the answer implies it doesn't align with established towing procedures. In reality, the other options are integral aspects of safe towing operations, helping manage the aircraft's stability and ensuring that the tow vehicle can maneuver effectively without risking damage or accidents.
