FlightGear é simulador de voo open-source que corre em plataformas Windows, Linux, Mac OS-X, FreeBSD, Solaris, e IRIX. A seguir podem ler-se as características chave deste jogo (em inglês) tal como no site. Vale mesmo o tempo de download, pois não fica muito atrás de outros que já experimentei: Microsoft Flight Simulator X, IL2 Sturmovik, D.I.D. Total Air War, Falcon 4 AF, e alguns outros.
Scenario
- Over 20,000 real world airports included in the full scenery set.
- Correct runway markings and placement, correct runway and approach lighting.
- Taxiways available for many larger airports (even including the green center line lights when appropriate.)
- Sloping runways (runways change elevation like they usually do in real life.)
- Directional airport lighting that smoothly changes intensity as your relative view direction changes.
- World scenery fits on 3 DVD’s. (I’m not sure that’s a feature or a problem!) But it means we have pretty detailed coverage of the entire world.
- Accurate terrain worldwide, based on the most recently released SRTM terrain data.) 3 arc second resolution (about 90m post spacing) for North and South America, Europe, Asia, Africa, and Australia.
- Scenery includes all vmap0 lakes, rivers, roads, railroads, cities, towns, land cover, etc.
- Nice scenery night lighting with ground lighting concentrated in urban areas (based on real maps) and headlights visible on major highways. This allows for realistic night VFR flying with the ability to spot towns and cities and follow roads.
- Scenery tiles are paged (loaded/unloaded) in a separate thread to minimize the frame rate hit when you need to load new areas.
Accurate and Detailed Sky Model
FlightGear implements extremely accurate time of day modeling with correctly placed sun, moon, stars, and planets for the specified time and date. FlightGear can track the current computer clock time in order to correctly place the sun, moon, stars, etc. in their current and proper place relative to the earth. If it’s dawn in Sydney right now, it’s dawn in the sim right now when you locate yourself in virtual Sydney. The sun, moon, stars, and planets all follow their correct courses through the sky. This modeling also correctly takes into account seasonal effects so you have 24 hour days north of the arctic circle in the summer, etc. We also illuminate the correctly placed moon with the correctly placed sun to get the correct phase of the moon for the current time/date, just like in real life.
Flexible and Open Aircraft Modeling System
FlightGear has the ability to model a wide variety of aircraft. Currently you can fly the 1903 Wright Flyer, strange flapping wing “ornithopters”, a 747 and A320, various military jets, and several light singles. FlightGear has the ability to model those aircraft and just about everything in between.FlightGear has extremely smooth and fluid instrument animation that updates at the same rate as your out-the-window view updates (i.e. as fast as your computer can crank, and not artificially limited and chunky like in some sims.)
FlightGear has the infrastructure to allow aircraft designers to build fully animated, fully operational, fully interactive 3d cockpits (which even update and display correctly from external chase plane views.)
FlightGear realistically models real world instrument behavior. Instruments that lag in real life, lag correctly in FlightGear, gyro drift is modeled correctly, the magnetic compass is subject to aircraft body forces — all those things that make real world flying a challenge.
FlightGear also accurately models many instrument and system failures. If the vacuum system fails, the HSI gyros spin down slowly with a corresponding degradation in response as well as a slowly increasing bias/error.
Moderate Hardware Requirements
The intention of FlightGear is to look nice, but not at the expense of other aspects of a realistic simulator. Our focus is not on competing in the “game” market and not on the ultra-flashy graphic tricks.The result is a simulator with moderate hardware requirements to run at smooth frame rates. You can be reasonably happy on a $500-1000 (USD) machine (possibly even less if you are careful) and don’t necessarily need $3000 (USD) worth of new hardware like you do with the many of the newest games.
That said, the more hardware you throw at FlightGear, the better it looks and runs, so don’t feel like you have to chuck your expensive new hardware if you just purchased it.
Internal Properties EXPOSED!
FlightGear allows users and aircraft designers access to a very large number of internal state variables via numerous internal and external access mechanisms. These state variables are organized into a convenient hierarchal “property” tree.Using the properties tree it is possible to monitor just about any internal state variable in FlightGear. It’s possible to remotely control FlightGear from an external script. You can create model animations, sound effects, instrument animations and network protocols for about any situation imaginable just by editing a small number of human readable configuration files. This is a powerful system that makes FlightGear immensely flexible, configurable, and adaptable.
Networking options
A number of networking options allow FlightGear to communicate with other instances of FlightGear, GPS receivers, external flight dynamics modules, external autopilot or control modules, as well as other software such as the Open Glass Cockpit project and the Atlas mapping utility.A generic input/output option allows for a user defined output protocol to a file, serial port or network client.
A multi player protocol is available for using FlightGear on a local network in a multi aircraft environment, for example to practice formation flight or for tower simulation purposes.
The powerful network options make it possible to synchronize several instances of FlightGear allowing for a multi-display, or even a cave environment. If all instances are running at the same frame rate consistently, it is possible to get extremely good and tight synchronization between displays.
