{{Main|Hybrid airship}}

A [[hybrid airship]] is a general term for an aircraft that combines characteristics of heavier-than-air (aeroplane or helicopter) and lighter-than-air technology. Examples include helicopter/airship hybrids intended for heavy lift applications and dynamic lift airships intended for long-range cruising. Most airships, when fully loaded with cargo and fuel, are usually ballasted to be heavier than air, and thus must use their propulsion system and shape to create aerodynamic lift, necessary to stay aloft. All airships can be operated to be slightly heavier than air at periods during flight ([[Descent (aircraft)|descent]]). Accordingly, the term "hybrid airship" refers to craft that obtain a significant portion of their lift from aerodynamic lift or other [[Kinetic energy|kinetic]] means.

For example, the [[Aeroscraft]] is a buoyancy assisted air vehicle that generates lift through a combination of aerodynamics, thrust vectoring and gas buoyancy generation and management, and for much of the time will fly heavier than air. Aeroscraft is [[Worldwide Aeros Corp]]oration's continuation of [[DARPA]]'s now cancelled [[Walrus HULA]] (Hybrid Ultra Large Aircraft) project.<ref>{{cite web | title = Aeroscraft.com | url=http://www.aeroscraft.com/ | access-date = 24 July 2010}}</ref>

The Patroller P3 hybrid airship developed by Advanced Hybrid Aircraft Ltd, BC, Canada, is a relatively small ({{convert|85,000|ft3|m3|abbr=on|disp=x|&thinsp;/&thinsp;}}) buoyant craft, manned by the crew of five and with the endurance of up to 72 hours. The flight-tests with the 40% RC scale model proved that such a craft can be launched and landed without a large team of strong ground-handlers.<ref>Vollrath, Jurgen.
