How can an aircraft's position be determined?

Determining an aircraft's position involves various methods, one of which is visual observation by controllers, pilots, or through systems like Airport Surface Detection Equipment (ASDE). This method is crucial, particularly in environments where other technologies may not be available or when visual cues supplement other data.

Visual identification is important for maintaining situational awareness. Ground controllers observe aircraft movements on the airport's maneuvering area and can confirm positions based on their line of sight, ensuring safe aircraft separation. Similarly, pilots can visually confirm other aircraft's positions, which is vital during takeoff, landing, and taxiing.

While radar, GPS, and radio communication play significant roles in position determination, they are not the only means. Each serves as a complement to visual observations rather than a standalone solution. Thus, the ability to ascertain an aircraft's position through immediate visual cues helps enhance safety and operational efficiency in air traffic control.
