Weather maps show current weather conditions in the United States and Canada. Planes take measurements using a special device called a meteorograph. Pilots also give information about temperature and conditions in the air. All of this information provides a broad understanding of weather patterns.
The pilot checks if the flight is safe. If it is, the flight dispatcher plans the flight. The pilot spoke with a meteorologist and flight dispatcher. They talked about cloud levels, weather conditions, storms, ice, and wind direction. He picks the height to fly the plane based on passenger safety and comfort and to avoid wind obstacles.
