Which system does the GPS NOT provide information to?

The GPS provides vital location and navigation data to various systems within an aircraft, enhancing situational awareness and operational efficiency. One such system that relies on GPS data is the Fuel Management system, which sometimes utilizes location data to optimize fuel efficiency based on the aircraft's route, altitude, and other factors. Hence, it does receive information from GPS to some extent.

In contrast, the WX radar system primarily relies on radar technology to provide data about weather conditions and does not utilize GPS for its core function of detecting and displaying meteorological phenomena. Hence, it does not depend on GPS information.

The Terrain Awareness and Warning System (TAWS) and Inertial Navigation System (IRS) are both systems that directly receive GPS data. TAWS uses GPS data to compare the aircraft's position against terrain elevations, providing alerts to prevent controlled flight into terrain. The IRS utilizes GPS data to augment its position calculations, improving navigation accuracy.

Therefore, among the options presented, the WX radar is the system that does not rely on GPS information, as it operates independently of positioning data provided by GPS.
