Which of the following is NOT an ATS position?

A weather forecaster is not an Air Traffic Services (ATS) position because their primary role is to provide meteorological information and forecasts to assist pilots and other aviation personnel in understanding weather conditions. While their work is indeed critical for operational decision-making in aviation, it does not involve direct management or sequencing of air traffic, which is the fundamental responsibility of ATS personnel.

In contrast, positions such as ground control and tower control are directly involved in controlling aircraft movements on the ground and during takeoff and landing, respectively. A flight service specialist also plays a crucial role within the ATS by offering flight planning services and disseminating information related to air traffic. Understanding the distinctions between these roles is key in the aviation field, as it clarifies the specific functions and responsibilities that support airspace safety and efficiency.
