Which of the following are types of GFA charts?

The correct choice pertains to the types of GFA (Graphic Forecast for Aviation) charts, which primarily focus on providing information critical for flight operations. GFA charts are designed to help pilots and meteorologists assess conditions that may affect aviation, including cloud cover and weather phenomena relevant to flight safety and efficiency.

The options related to clouds and weather contain vital information, such as the presence of significant weather systems, cloud types, and coverage, which directly impact flight operations, making it a key element in visualizing weather-related aviation criteria.

While other options presented include measurements of atmospheric conditions, they do not specifically classify as GFA chart types. For instance, visibility and wind can affect flights but are not the primary focus of GFA charts in the same categorized manner as clouds and weather. Similarly, temperature and pressure are essential meteorological data but do not fall under the core types identified within GFA charts.

Thus, clouds and weather represent the specific visual data that GFA charts are designed to convey to ensure safe and efficient flight planning and operations.
