What is the main criterion that prevents an aerial from being used to meet floor SR requirements?

In the context of gymnastics, particularly within the Level 10 floor routine, the specific criteria regarding the use of aerials relate to their ability to fulfill the skill requirements (SRs) on the floor exercise. The main criterion that prevents an aerial from being used to meet SR requirements is that aerials, by themselves, cannot satisfy the proficiency necessary for these requirements.

Aerials are considered non-salto elements, and while they may be aesthetically pleasing and contribute to the overall routine, they lack the dynamic quality required for fulfilling certain skill requirements on the floor. In Level 10 routines, the judges need to see a specific connection of skills that demonstrate not only the dancer's ability but also the acrobatic nature of the performance, typically showcased through salti. Thus, relying solely on an aerial does not meet the standards set forth for skill execution at this level, leading to the understanding that aerials cannot individually satisfy the skill requirement criteria.
