What is the primary advantage of using GPS in aviation?

The primary advantage of using GPS in aviation is accurate navigation and positioning. GPS provides pilots with precise location data, allowing them to determine their exact position in relation to their flight path and intended destination. This accuracy helps improve situational awareness, enhances safety, and allows for more efficient routing through controlled airspace.

In aviation, precise navigation is essential for maintaining safe separation from other aircraft and for following designated flight routes. The use of GPS reduces the reliance on traditional navigation aids, which can sometimes be less accurate or unavailable. With GPS, pilots can execute approaches and departures with a high level of precision, leading to more reliable and consistent flight operations.

Other options do not align with the primary purpose of GPS. In-flight entertainment is not related to navigation but rather enhances passenger experience. Weather forecasting is typically done through different technologies and sources that analyze meteorological data rather than through GPS. Although communication with air traffic control is vital for flight safety, it does not involve GPS directly, as ATC relies more on radar and voice communication.
