Two software packages are currently available that enable computer users to construct and print sequences that conform to the regulations which control the categories and programmes operated by CIVA.
OpenAero is free aerobatic sequence design software authored by Ringo Massa that runs inside your web browser. It works in almost any desk, laptop, phone or tablet computer operating system that supports internet browsing.
OpenAero software is made available under the terms of the GNU General Public License as published by the Free Software Foundation. It is loosely based on OLAN sequence coding originally published by Michael Golan.
To use this software - simply click on this link or navigate your internet browser to https://openaero.net/ and the latest version will appear. If you are new to OpenAero or are having a tricky time getting something to work as expected then click the Help > Manual menu item to open the comprehensive technical help system.
Aresti System software was developed in the early 1990's by Alan Cassidy. It works in conjunction with the graphic and logic capabilities of Microsoft's Visio drawing software package, which must also be present in the users' computer.
Legacy versions of the Aresti software remain usable with MS Visio. Development and updates to the code and its reference database beyond 2020 however appears unlikely.
