What is the purpose of a GPS in aviation?

The purpose of GPS (Global Positioning System) in aviation is primarily to provide precise location and navigation information. GPS uses a network of satellites to determine an aircraft's exact position on Earth, allowing for accurate navigation and route planning. This capability helps pilots navigate effectively by offering real-time information on their location, speed, and direction. As a result, pilots can make informed decisions about their flight paths, ensuring safe and efficient travel from one point to another. The precise navigation information provided by GPS also enhances situational awareness in the cockpit, contributing to overall safety in aviation environments.

The other options, while relevant to aviation operations, do not accurately reflect the primary purpose of GPS. Communicating with air traffic control involves radio communications, which is separate from navigation technology. Recording flight data is typically done by flight data recorders, and measuring fuel consumption is more related to onboard instruments rather than GPS functionality. Thus, the correct choice emphasizes the role of GPS in delivering essential navigational assistance.
