Final answer:
The subject of the question is aviation, and it involves determining the number of safety cones required for an MD80 turn flight with no ventral stairs.
Step-by-step explanation:
The subject of this question is Aviation. The question pertains to determining the number of safety cones required for the arriving MD80 turn flight when no ventral stairs are used.
When an aircraft like the MD80 turns around, it usually uses ventral stairs for passenger boarding and deboarding. However, in this case, no ventral stairs are used, which means alternative measures need to be taken to ensure safety.
In aviation, safety cones are commonly used to mark potential hazards on the ground. They are placed around the aircraft to create a safe working area for ground personnel. The number of safety cones required for a specific aircraft depends on the size of the aircraft and the extent of the work being performed.
Safety cones are commonly used in aviation to mark hazards and create safe working areas. The number of cones needed depends on the aircraft size and work being done.
