What is one unique feature of the FMQ-19 system?

The FMQ-19 system is specifically designed to deliver weather data for specific locations, making this choice the unique feature of the system. One of its primary functions is to provide real-time meteorological information that is crucial for operational planning and safety in aviation. By supplying localized weather data, it enables more informed decision-making during flight operations, ensuring the safety and efficiency of missions.

While historical flight data and radar avoidance information are important aspects of air operation systems, they do not capture the distinctive purpose of the FMQ-19. Similarly, while ground navigation is integral to many aviation systems, it is not a defining feature of the FMQ-19. The emphasis on weather data distinguishes this system and highlights its key role in enhancing situational awareness for airborne operations.
