Getting the algorithms right, and keeping the data up to date every 7 weeks (we have only a tiny sliver of that data currently), is going to be much more of a challenge. I expect that it's probably an order of magnitude more complicated than our current flight dynamics (etc.), so we'd have to grow our contributor base, and find funding to pay at least Curt (and maybe a couple of others) full time to manage the project. Note that that's what has happened for other complex FOSS projects, like office suites and browsers, which generally end up working through a foundation, rather than our current relaxed circle-of-friends arrangement. The reason it's so much harder now is that the software *is* the product for GPS navigators, FMSs, etc. (unlike with older avionics, where the hardware was the main thing). That means that emulating even a simple unit like the GTN 650 or GNS 430W is almost difficult as building one, so we're trying to keep up with armies of full-time software developers at Garmin, Avidyne, etc.<ref>{{cite web

According to the Route Manager wiki page, we already have support for SID/STAR data provided from Navigraph, which is released on the AIRAC cycle, and costs a pretty small amount (9 EUR for a single download of FMS data, or 90 EUR per year) Given the relatively low cost, I don't think that we as an organiation want to get into trying to digitize data ourselves just to make it open-source or public domain. Particularly given the low cost of a download. We might want to digitize the STAR/SIDs for the default airport with each release so there are some approaches available for those who don't want to purchase the data.<ref>{{cite web
