How to escape from the cumulonimbus clouds in front when the plane is flying on the channel?

1 first of all, when the plane cruises normally, most modern passenger planes cruise at an altitude of 10,000 meters. The obstacle at this height can only be another plane, and the air traffic controller's accusation is to schedule the interval between planes and cruise the altitude to prevent the planes from colliding. There are also corresponding flight rules to stagger the aircraft. Even if the air traffic controller neglects his duty and makes a mistake, the TCAS collision avoidance system is installed on the plane. As long as the anti-collision system is activated, the air traffic controller will resign directly. A collision in the air is almost impossible.

2. When the plane flies at a low altitude, you will think that you may meet a tall building on the ground. This situation is unlikely to happen. The route map strictly stipulates the flight route of the aircraft and will avoid or mark these tall buildings. And even flying at low altitude will be much higher than buildings. During the take-off and landing phase, there will be no tall buildings at both ends of the runway.
