Based on the OpenSceneGraph (OSG) graphics engine. Graphics is decent, but FlightGear is a simulator, not an arcade. Physics and aerodynamics are more important than ease of operation and without a basic knowledge of the management of real equipment, you will not be able to take off.
FlightGear was created as an aircraft simulator for research and educational purposes, flight modeling. You can play both alone and online. Versions are available for Linux, FreeBSD, Mac OS X and Windows. Distributed under GPL license.
FlightGear World Scenery contains a map of the surface of the earth, descriptions of rivers, roads, towns and airfields, weighs more than 13GB. It doesn’t make sense to pump it right away, first, get used to the built-in maps and models.
You can install FlightGear through the package manager of your Linux distribution (packages will be called flightgear or fgfs). You can download the official build from the official FlightGear website.
You can start the aircraft simulator with the terminal command fgfs. By default you will find yourself in a Cessna 172 aircraft at the San Francisco airport. You can specify the airport and the model of the plane as follows:
fgfs --aircraft=aircraft_model --airport=airport
You can get the list of available planes with the following command:
Those who launch FlightGear for the first time can spend the whole evening looking for a “gas” button and, without finding it, remove this wonderful aircraft simulator. Therefore, I say at once – if you want an arcade with easy control and a basic slope on the graphics, FlightGear is not for you. The control is complicated and I wouldn’t even call FlightGear a game, it’s a tool for those who know the subject. And the necessary documentation can be obtained in large quantities on the official website of the simulator.
