Lighter-than-air Craft -

The choice of gas determines the lift capacity and safety profile of the craft:

Lighter-than-air (LTA) craft, also known as , operate on the principle of buoyancy—displacing a volume of air with a gas that is less dense, thereby creating upward lift. Unlike airplanes, which rely on aerodynamic lift generated by movement through the air, LTA craft can remain aloft while stationary. 1. Types of LTA Craft lighter-than-air craft

: Powered, steerable aerostats equipped with engines and control surfaces like rudders and elevators for navigation. The choice of gas determines the lift capacity

: Unpowered aerostats that drift with the wind or are tethered in place. Pilots primarily control altitude by adjusting the gas temperature or releasing ballast. also known as

: Rely entirely on internal gas pressure to maintain their shape.
