What is the sole determining factor in the certification of a new Site Controller candidate?

The certification of a new Site Controller candidate hinges primarily on flight line performance. This aspect is vital because it encompasses the candidate's ability to demonstrate practical skills, manage the operation of the Skycoaster, and ensure safety during the flight line processes. Having strong flight line performance indicates that the candidate can effectively handle real-time situations, communicate with riders, and maintain an operational flow while prioritizing safety.

While experience in the field, knowledge of safety protocols, and completion of training are significant factors contributing to a candidate's overall qualifications, they do not singularly determine certification. Flight line performance is the practical application of all the prior knowledge and training, showcasing the candidate’s readiness to manage the responsibilities of a Site Controller effectively. Hence, successful execution in this area is deemed the most critical factor for certification.
