乘坐飞机为什么必须系安全带？
乘坐飞机必须系安全带，主要是为了在飞机颠簸或发生意外时保护乘客安全、防止乘客在舱内碰撞以及确保紧急疏散时通道畅通，具体如下：
1、保护乘客安全：飞机在高空飞行时，可能会遇到气流颠簸。系好安全带可以防止乘客在座位上移动，避免因突然的颠簸而撞到座位或其他物体，从而保护乘客的安全。
2、防止乘客在舱内碰撞：在飞机起飞、降落或遇到突发情况时，乘客可能会因为惯性而向前冲。安全带可以将乘客固定在座位上，防止其在舱内碰撞，减少受伤的风险。
3、确保紧急疏散时通道畅通：在紧急情况下，如飞机迫降或发生火灾，乘客需要迅速疏散。系好安全带可以确保乘客在疏散过程中不会阻碍通道，使紧急疏散更加有序和高效。
总结：乘坐飞机必须系安全带，主要是为了在飞机颠簸或发生意外时保护乘客安全、防止乘客在舱内碰撞以及确保紧急疏散时通道畅通。
