Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Yes, provided the seller is in compliance with a number of conditions detailed in the GPL.

After considerable negative criticism from the FlightGear community, FlightProSim offered to fund a competition in which developers of new features might be rewarded with a sum of money ($250). The FlightGear developers have more or less un-officially decided to ignore this offer. Some reasons reasons include:
+
No. No such payment is required, as FlightGear is GPL software. No such payment has been offered, no such payment has been made. Any claims by FlightProSim that they support the FlightGear project are entirely wishful thinking on their part.  
* If the people behind FPS really is interested in improving a flight sim, he would input his addons/improvements back into the FlightGear community so the software can be further developed.
+
* Anyone is allowed to sell FlightGear, as long as they comply with the GNU GPL v2 license. Prior to complaints from the community, FPS did not even acknowledge that their product was derived from GPL software or content, or make any effort to comply with the terms of the license. The current compliance constitutes the barest legal minimum, i.e one (small) link from the FPS website.
+
* FlightProSim copied all content from this wiki (and initially, also the main website), further reinforcing the feeling that they are more interested in appearing to have a product of their own, than helping to collaborate or develop a community project.

Revision as of 16:04, 25 November 2010

As many people will be aware, there is a new flight simulator product that is being widely and actively marketed at the moment - FlightProSim (also promoted as ProFlightSimulator, FlightSimPro). As it is almost entirely based on FlightGear, there is some confusion between the two. To help provide some clarity, and answer some common questions, we (the core FlightGear development team) felt it was appropriate to make a statement, and provide a FAQ.

FlightGear is an open-source flight simulator that was started in 1996. It is released under the GNU General Public License v2, and as such, it is free to use, modify and distribute with few restrictions. It has been developed with the collaboration of a large number of individuals over the last 12 years. FlightGear can be downloaded at no cost from http://www.flightgear.org.

FlightProSim is a commercial product very heavily based on FlightGear. Investigation by a number of the FlightGear developers has found no difference between this and the FlightGear v1.9.1 release other than a change of name. FlightProSim is in no way endorsed or supported by the core FlightGear development team.

Given the similarities between FlightProSim and FlightGear, we would recommend that prospective buyers download FlightGear for free and satisfy themselves that FlightProSim provides worthwhile value for money before purchasing it.

What are the differences between the two?

As far as we have been able to make out, the only difference between FlightGear v1.9.1 and FlightProSim is a change in name throughout the software, and the fact that you have to pay for it.

Legal or illegal?

The GNU GPL license, under which FlightGear is released, allows reselling under certain terms. The main issue that FlightGear developers have is the misleading marketing tactics used by pro flight sim that target unsuspecting users who aren't yet familiar with FlightGear. This is primarily an ethical, not a legal issue.

Is it legal to sell a copy of FlightGear, whether re-branded or not?

Yes, provided the seller is in compliance with a number of conditions detailed in the GPL. In fact, those interested in receiving a DVD containing FlightGear may do so through the main FlightGear website, and directly contribute to the project (though they may want to wait for the upcoming release in the new year).

Has FlightProSim paid any money to FlightGear for the rights to the program?

No. No such payment is required, as FlightGear is GPL software. No such payment has been offered, no such payment has been made. Any claims by FlightProSim that they support the FlightGear project are entirely wishful thinking on their part.

Why do the FlightGear developers allow this?

The freedom to modify and enhance FlightGear is a core part of the project, and of open-source in general. Restricting the modifications that are allowed and what people can do with the software goes against that ethos.

Is there any relationship between the makers of FlightProSim and the FlightGear Project?

No.

Has Flight Pro Sim contributed to the FlightGear project at all?

No.

I have purchased Flight Pro Sim. Can I get a refund?

That is something you will have to take up with the distributors of FlightProSim. They guarentee a 60 day money back trial period, so this should be no problem if you react quickly.

This whole situation makes me upset! What can I do?

First of all, the main problem here is the marketing tactics used by FlightProSim which exhibit very dubious ethical values. The FlightGear development teams feels the best way to combat this problem is through positive FlightGear marketing and by honestly pointing out that FlightProSim is simply a rebranding of an already free flight sim called FlightGear.

We want all of you to stay positive, to be honest and to be fair!

If you want to help combat misleading marketing, lets all get the word out about FlightGear. FlightGear doesn't have the kind of advertising budget that the FlightProSim guys do. We need you!!! Please post where ever you can on web sites, forums, blogs, facebook, etc. We don't mind if someone chooses to buy FlightProSim, in fact that's great, as long as they have complete information in advance and aren't being misled by a slimy sales pitch that sounds too good to be true.

So let's get the word out and try to make sure that FlightProSim has to market to an "educated" audience!
