Which aircraft types utilize the lightweight "grabber" type tow bar?

The lightweight "grabber" type tow bar is designed for specific aircraft types that are typically on the smaller side, making it easier to maneuver during ground handling. The correct answer focuses on the A220, A319, A320, and A321, which are all narrow-body aircraft. These planes have a lower weight and require less heavy-duty equipment for towing compared to larger aircraft. The grabber tow bar’s lightweight design allows for efficient attachment to these aircraft, facilitating easier movements around the ramp.

In contrast, larger aircraft like the B767 and A330 require more robust towing equipment due to their weight and size, making them less suited for the lightweight grabber type. Similarly, the B737 and B757 are also medium-sized aircraft that may use more traditional tow bars suited for their dimensions. The CRJ and B717, while also smaller aircraft, would typically not utilize this specific tow bar design either, as their operational requirements may dictate different equipment. This all highlights the importance of matching the type of tow bar to the specific aircraft for safety and efficiency during ground operations.
