An airship descends by releasing lift gas, typically helium or hydrogen, or by adjusting the weight. The pilot can let out some of the gas through a valve or use ballast to increase the weight, causing the airship to sink. Additionally, the descent can be controlled by adjusting the angle of the propellers or rudders. This allows for a gradual and controlled descent to ensure safety and stability.
