What are the different flight modes?
The different flight modes are: flag, bird, static or dynamic.
Flag flight: held by a halyard at the masthead, the kite is placed in the wind bed and does not generate traction.
Bird mode: only the central part of the kite carries in the wind, the “feathers” fade away generating drag and the kite is self-stable. This mode is used for a safe launch and recovery of the kite. This mode is also specific to Beyond the Sea.
Static flight: a flight mode where the kite is not moving and will remain stationary in the air. Dynamic flight: the kite describes 8’s and the traction force is between the wind direction and its perpendicular. The traction is maximum.
A sketch (text in French language) is shown page 5 of:
Translation:
Different modes of use :
- Static tucked in: fixed kite, traction
medium- Static shocked: low traction,
- Dynamic: kite describing 8, strong traction,
Dynamic: wind direction
Static, perpendicular to wind direction
So in static mode of flight, the kite also flies (more or less) crosswind but without describing 8, and in a less favorable position in the flight window.

Le SeaKite in Bassin d’Arcachon
27 334 vues 17 sept. 2024 BASSIN D’ARCACHON
Le SeaKite, demonstrator catamaran for the automated kite traction system SeaKite for ships, is currently sailing in the Bassin d’Arcachon with its 50-square-meter kite system. This innovative setup allows the vessel to harness wind power more efficiently, showcasing a sustainable solution for maritime transport. The SeaKite’s cutting-edge technology aims to reduce fuel consumption and emissions, demonstrating the potential of kite-based propulsion systems for the future of eco-friendly shipping.
