FlightGear Newsletter June 2014: Difference between revisions

Thanks to Tom's and James' recent work on the upcoming [[Aircraft Center]] for downloading and switching between aircraft without having to exit FlightGear, beginning with FlightGear 3.2, FlightGear's [[Canvas]]-based GUI will contain support for so called [[Canvas MessageBox|Message Boxes]]:

The development team at FGUK have been experimenting with modelling aircraft damage in a number of different ways. First of all, Tomaskom has used the particle system carefully to produce visually impressive fireballs and smoke columns with very little FPS impact. First seen in his V-1, we hope to adapt this to simulate realistic fireballs for ground impacts (where appropriate). For the moment, it explodes with the full force of a V-1's explosive payload. On the right is a video excerpt from the #FlightNight which Tom organised to debut the V-1, where we all had '''way''' too much fun bombing London. As you can see, the smoke is visible from quite a long way away from the impact, and despite two fires burning with huge smoke columns, and over ten multiplayer aircraft within model range, the frame rates are still more than acceptable. StuartC has already integrated the explosion and fireball into several development aircraft, and we expect eventually to combine it with the disintegration code and make the size of the explosion dependent on fuel load etc.

Finally, and most spectacularly, Tomaskom has demonstrated the disintegration capabilities of his L-159, which is under development. Hopefully, he will explain all here before publication date.

Scenesetter is a piece of code by Algernon, very early in development but already quite effective, which can effect changes to the time and weather from an AI scenario synchronously with other MP players. A crude proof of concept was used in the recent FGUK #FlightNight "British Weather", where pilots visited different airfields with various unpleasant flying conditions. Scenesetter pushes METAR strings to the FlightGear weather system based on the location of an associated Navaid, establishing a circular zone of a specified radius around it in which METAR will be changed. Start time can be specified too, either by providing a local start time or a local time offset (useful for Multiplayer use where players will not all start the AI scenario at precisely the same time).

The Swedish fighter jet [[Saab JA-37 Viggen]] has been updated, since it was included in FlightGear 3.0. More instruments, additional liveries, aerodynamic response to payload and tooltips on instruments. Option for automatic reverse thrust at touchdown, selection of HUD brightness, disabling of structural damage. HUD can now switch to imperial units and show MP and AI aircraft and closest airport. The aircraft now also has multiplayer sounds and better cockpit view helps seeing the landing strip. Support for FG 2.8 by deleting a small section in an xml file. Also worth mentioning is countless bug-fixes and improvements, e.g. better handling at high altitudes and a bug fix in the lift force formula.

After he started developing the [[Boeing 747-400]] as a hobby project six years ago, Gijs finally managed to get the weight and balancing right. The center of gravity is now within 0.05% MAC (40 cm) of the published values.

The updated 747-400 is already available through Git and will be on the download page when FlightGear 3.2 is released.

* Engine+fuel: realistic flame-out, fuel flow to collector compartment, anti ice influence on TOT, improved oil press and temp model<br/>

* Aerodynamics: flap performance, elevator-30deg-flaps authority improvement<br/>

* Avionics: IFD moving map, automatic NAV tuning, automatic NAV switching, magnetic variation fixes<br/>

* Autopilot: added OBS and fly vectors mode, significant improvement of coupled ILS performance

Please checkout the [[Extra EA-500|Extra500 wiki]] for download instructions and lots of more info.

There is a project to add all the USA state capital buildings into FG.  It is discussed in [http://forum.flightgear.org/viewtopic.php?f=5&t=22715&sid=ea847909bde2e1f8ffe5b94bcc673f4f this scenery forum thread]. There is also a wiki page: [[State Capitol Buildings in the United States]].  So far, Idaho, Louisiana & Nebraska have been completed. Hawaii and New York are currently in progress.  Please feel free to join in with any other state that has not been done yet.  Just let us know through the forum and we will add it to the in progress list.

This month saw the [http://forum.flightgear.org/viewtopic.php?f=5&t=22623 second "preview" release] of the conversion of a scenery for MS Flight Simulator, [[Falconara Airport]] (ICAO code: LIPY), a small Italian international airport halfway down the Adriatic coast. The original author granted the permission to the conversion and even allowed for it to be included in the FlightGear official [[World Scenery]], at least the GPL compatible parts. This is not a huge limitation though, because most of the material was created from scratch, included pictures taken on purpose at the real airport, with the authorities' collaboration. Copyrighted aerial imagery only include the (unsuable) photoreal ground and some roofs.

{{cquote|I really wanted to have this scenery in FG because it's my home base, and seeing it ready and so well done just made me want it. However, even if still easier than making it from scratch (even if reusing the textures), I'd have to think well if I had to do this again.|bigstones, maintainer of the conversion}}

In FlightGear Germany's second largest cargo airport [[EDDP]] is well known as a detailed model accessible for everybody via [[TerraSync]]. Until 2013 it was famous for its regular ATC-events. It has been updated several times, at least 2012 by users D-STHO and August. When FlightGear 3.0 was published the airport layout changed from the old 810-standard to the new 850-standard. But the update (based on a taxiway layout modelled for X-Plane) turned out to be very imperfect. Many aprons and taxiways did not exist, dimensions did not appear to be correct and many new facilities which had been added at the real-world airport had not been taken into account. So maintainer August decided to redesign the whole airport from the scratch using [[WorldEditor]].  

Feedback is welcome at [[User talk:August|August's wiki page]].

The [[Weather]] wiki article went through a wide extension. Although Advanced Weather was released quite a while ago, its usage has never been explained in the wiki, and some thorough instructions were available only in a readme in the "docs" folder of the base package which is not commonly explored by users, while the wiki article [[Advanced weather]] is more about the project than the usage.

AW's advanced configuration is known to be not easy. So, if you always only used the weather selection menu and want to know more, or want to understand what the options actually do and how you can combine them, the [[Weather]] article has now been updated with some hints and basic notions extracted from experience and the original documentation, and quality checked by the author of the AW weather engine.
