Longitudinal Force Balance and Trim,WIG trim is controlled by the dynamic balance of environmental loads against restoring forces from the flying surfaces – the main lifting wing and tailplane. Mean running trim when flying is generally adjusted by moving the neutral position of the control surfaces and so altering the centre of lift relative to centre of gravity.

Hovering and Slow-Speed Performance,The four main types of WIG design each use a different approach to aerodynamic support at zero and slow speeds. This is partly due to the primary design target – the cruise performance of each craft type.

Calm Water Drag and Power,Analysis of WIG drag forces uses a combination of techniques adapted from other high-speed marine vehicles, such as seaplanes, catamarans, SES and ACV. There are more operating modes to contend with for WIG, however, as they can operate hull borne and air cushion borne as well as flying in ground effect.
