The Open Group Architecture Framework (TOGAF) Practice Exam

In a simple airport system, which tool is commonly used by pilots and controllers?

1. Altitude

2. Fuel

3. Radar

4. Radio

The correct answer is: Radio

The tool commonly used by pilots and controllers in a simple airport system is a radio. Radios facilitate communication between pilots and air traffic controllers, enabling clear and accurate exchanges of vital information such as flight instructions, weather conditions, and any necessary alerts about air traffic. This communication is essential for maintaining safety and coordinating operations within the airspace and airport environment. While altitude, fuel, and radar are all important elements in aviation, they do not serve the same direct role in facilitating real-time communication between pilots and air traffic control. Altitude refers to the height of the aircraft above sea level, which is a critical operational parameter but not a communication tool. Fuel is essential for the operation of an aircraft, impacting the range and duration of flights, but it is not a tool for communication. Radar is used for tracking the position of aircraft and detecting obstacles in the airspace, helping air traffic controllers maintain awareness of traffic. However, radar does not provide a means for pilots and controllers to converse and share immediate instructions or updates. Thus, the radio stands out as the primary tool for direct communication in this context.
