Which factor is crucial when determining if to use STARS data on TDW?

Using STARS (Standard Terminal Automation Replacement System) data on Terminal Display Workstations (TDW) involves considering several key factors that impact the safety and efficiency of air traffic management. Weather conditions play a critical role in this decision-making process. Adverse weather, such as storms or low visibility, can significantly affect aircraft operations, necessitating the use of STARS data to enhance situational awareness and inform air traffic controllers about the most current conditions. STARS data offers tools to manage these challenges effectively, helping controllers make informed decisions based on the latest information regarding aircraft positions and potential hazards.

While time of day, volume of air traffic, and type of airspace are all important considerations, they do not carry the same immediate operational implications as weather conditions. For example, during adverse weather situations, the decision to utilize STARS becomes more pressing due to the increased complexity of maneuvers and the need for clear communication among various stakeholders in air traffic control. Thus, the emphasis on weather conditions highlights their crucial nature in ensuring the safe management of air traffic using STARS data on TDW.
