C-17 Tow Supervisor and Brake Operator Pre-Test Practice

The main idea here is to ensure the towing connection is solid and moves as one unit before you start moving the aircraft. A pull test checks that the tow bar is securely attached to both the aircraft and the tow tractor, with no looseness or play, and that applying force causes the system to move smoothly without binding or misalignment. This readiness prevents the tow bar from disengaging, binding, or forcing the nose gear out of alignment during towing, which could cause damage or injury. It’s about confirming a proper, safe connection and alignment, not about color, radio range, or whether the tow bar can fold.
