How did the plane escape from the cumulonimbus clouds when it was flying on the fairway?

Any thunderstorm should be regarded as dangerous. For severe thunderstorms or thunderstorms with strong radar reflection echo, avoid at least 20 nautical miles. If there is an obvious thunderstorm activity area within 20 kilometers of the airport, the captain should consider taking off or landing in the opposite direction of the thunderstorm area, or delaying the take-off and landing. If possible, it's better to fly between thunderstorms with enough distance, instead of flying directly on it. When flying around outside the cloud, the distance from the cumulonimbus cloud (cumulonimbus cloud) shall not be less than 5km during the day and10 km at night; When the distance between two clouds is not less than 20 kilometers, they can pass through the middle; It is only allowed to fly around the thunderstorm visually from under the cloud during the day, but the vertical distance between the plane and the cloud bottom shall not be less than 400 meters. In principle, flying thunderstorms should fly at least 8km,16km and 32km from the windward direction at 6000m, 7500m and 9000m respectively. Before take-off, when there is a thunderstorm in the weather forecast or actual weather, the crew should turn on the airborne radar, determine the location of the thunderstorm, and choose the flight bypass route to prevent it from entering the thunderstorm area by mistake. In flight, radar should be used in time. According to the answer to a big question in the final exam last semester, the general meteorological department will notify in advance (if it is foreseeable), and then the flight plan before takeoff will be diverted. If it is sudden, the controller will give advice and all relevant information, which will be decided by the pilot. In terms of meteorology, it is recommended to pay attention to WSI company in the United States, which provides the most advanced meteorological forecasting solutions in the world. Red is the area with the strongest precipitation (the principle of airborne radar is to detect water vapor), and this is often accompanied by strong discharge, followed by yellow. Of course, the green area on the edge should not be underestimated. At this time, apply to the controller for a suitable course, tilt the orchid finger (literary pilot) and twist the knob to bypass the weather.
