Final answer:
When connecting a pushback tractor and towbar to an Airbus on a turn flight, safety cones must be positioned around the aircraft to ensure visibility and alertness. These cones, along with other safety measures, help prevent accidents and ensure ground crew's safety.
Step-by-step explanation:
When a pushback tractor and towbar are connected to an Airbus on a turn flight, there must be safety cones positioned around the aircraft for safety reasons. These cones serve as visual markers to alert ground crew and other aircraft about the presence of the plane being pushed back.
Safety cones typically have bright colors and are placed strategically around the Airbus to ensure that they are clearly visible. The number of cones required varies depending on the specific airline's safety protocols, but it is important to have enough cones to clearly indicate the boundaries of the aircraft's movement area.
In addition to cones, ground crew may also use other safety measures such as warning signs or flagmen to further enhance safety during the pushback process.
