What is an advantage of using GPS for navigation?

The advantage of using GPS for navigation lies in the increased accuracy and efficiency it offers in determining flight paths and positions. GPS technology allows aircraft to pinpoint their location with a high degree of precision, which is crucial for flight safety, effective route planning, and efficient airspace utilization. By utilizing GPS, pilots and dispatchers can obtain real-time data about their position in relation to the intended flight path, enabling adjustments and corrective measures to be taken swiftly if necessary. Moreover, this accuracy helps in managing air traffic flow and can lead to more optimal fuel usage and reduced flight times.

Using GPS does not negate the need for communication with air traffic control; on the contrary, it complements it by providing more reliable positional information that can help in maintaining safe separation from other aircraft. A flight plan is still a requirement even when using GPS, ensuring that all parties are aware of the intended route and any changes that may occur. Additionally, while GPS can provide situational awareness, it does not offer visual navigation aids traditionally used in cockpit displays or at airports.
