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

FlightGear 2.4.0 ChangeLog

The FlightGear development team is happy to announce the release of FlightGear 2.4.0. This new version contains many exciting new features, enhancements, bugfixes, and other improvements.

By adopting the newly available shader technology, FlightGear’s graphical quality has been substantially improved, compared to the previous release. Assorted highlights of this version include: new shader based water textures, capturing the sun’s reflection, three dimensional city block textures, more realistic rendering of rocks and mountains, a configurable local weather system, many new and improved aircraft, and numerous scenery additions.

Some of the major changes include:

Aircraft operations:

  • A new head-up display (HUD) system
  • An in-sim moving map
  • ATC/ATIS improvements
  • Improved autopilots
  • Indicated airspeed (IAS) limitations can be indicated on the airspeed indicator
  • TCAS, works with AI and multiplayer aircraft, provides aural warnings for conflicting traffic and is also capable of driving a realistic traffic display. AI aircraft also respond to TCAS alerts and take evasive action
  • Updates to the KLN89
  • Wind-up prevention on simple autopilot systems Moved to Interface

AI system

  • A standalone AI flightplan generator program
  • Approaching aircraft now follow realistic approach trajectories.
  • Ballistic objects can be slaved to any AI object
  • Improved AI ballistics behavior
  • More communication / interaction between AI aircraft and ground. Support for multiple frequencies for AI/ATC interaction.
  • Speed-up for AI traffic initialization by means of an aircraft usage statistics collection mechanism

AI Traffic

  • General and commercial aviation traffic at LOWI airport
  • Malaysian Airways / Kuala Lumpur based traffic
  • Traffic for Adria (Croatia)

Flight dynamics

  • A new MIL-STD Turbulence model has been added to the JSBSim flight dynamics simulation engine

Environment

  • A local weather system to simulate physically correct local weather phenomena
  • Discard of outdated METAR weather information sources and improved METAR parsing
  • New Fog layers with limited elevation
  • Scenery can be downloaded and installed on-the-fly via an in-sim TerraSync interface
  • Specific multiplayer pilots can be selectively ignored

Interface

  • Complete overhaul of the autopilot system
    • New digital controllers
    • Flexible use of input and output values
    • Support for mathematical expressions
    • Usable for generic numeric data processing as a "property rule" system
  • Better integration of separate weather systems
  • New support of draggable 3d objects like throttle-levers
  • Support for textures generated from VNC clients.
  • Unified runway selection code that is shared between user controlled and AI controlled aircraft.
  • New HLA interface for distributed simulations
  • New on demand loading of Nasal modules
  • New support for external (aka real) Garmin 400/500 WAAS Units

Highlighted new and improved aircraft

  • A new and highly detailed IAR-80 (a Romanian-produced WW2 fighter)
  • A new highly detailed piper Cub
  • An improved P-51D, completely remodeled and containing improved flight dynamics
  • Boeing 717 and 757
  • Bombardier CRJ-900
  • CRJ 200
  • Douglas A-4F Skyhawk
  • Improvements to the Boeing 787
  • MiG-15bis
  • PZL-Mielec M18B "Dromader"
  • Short S.23 Empire flying boat
  • The Boeing 737NG Series
  • The Boeing 747-400 has received night lighting effects
  • The Douglas DC-8 Series
  • The Eurocopter EC130 B4 Helicopter
  • Tyre smoke effects on many aircraft
  • Zeppeling L121 Nordstern

Navigation

  • A new route manager
  • Autopilots can be driven by NAV or GPS instruments
  • The beginnings of an EICAS instrument are available on a selected number of aircraft.

Project infrastructure

  • Change to Git as revision control system
  • Moved to cmake based build system
  • Set up a bug tracker
  • Support for automatic nightly snapshot releases
  • Support for placing addon aircraft in a separate aircraft directory, separate from the main data directory

Scenery improvements

  • Animated jetways
  • Improvements to the Innsbruck area, Austria
  • Las Vegas McCarran Intl. Airport
  • London Gatwick Airport
  • Many buildings for small airports in the Italian Alps
  • Many contributions to the Switzerland area, including building models and shapefiles for future terrain improvements
  • Many historic and current launch sites have been added to the Kennedy Space Center Area, including some AI controlled rocket launches
  • The city of Dubai (terrain, city buildings and AI traffic)
  • Time dependent placement of buildings.

Visual effects

  • Native multi-screen support
  • Various graphics improvements using shaders, including 3D urban effects, reflections, water, rock textures, lightmaps, skydome scattering.
  • Easy GUI-based access to a host of stereoscopic 3D rendering effects
  • Panoramic distortion
  • Persistent contrails
  • New standalone 2D-Panel rendering utility

Bug fixes

  • Fixed METAR weather http requests from NOAA
  • Fixed many sources of the infamous NaN errors
  • Fixed many potential memory leaks
  • Improved placement of random objects
  • Inconsistencies in scenery tile scheduling
  • The replay system now works again as advertised
  • Many, many more
