Microsoft Flight Simulator Update III Released

Asobo Studio has announced Sim Update III is now available for the new Microsoft Flight Simulator platform.


The new version adds a host of features such as visible contrails on the player's aircraft and an option to match aircraft to specific real-world examples. Refinements have been made to the in-sim aircraft such as a more accurate centre of gravity, fuselage wear on older aircraft results in higher parasitic drag and adjustments have been made to the control surface limits.

Various improvements and fixes continue to be made to the avionics, autopilot and FMS systems along with additional functionality. The glass cockpits for general aviation aircraft have also seen some bug fixes applied and the engine modelling and flight dynamics for general aviation and airliners have been improved as well as updates to the aircraft lighting.

Finally, the latest AIRAC cycle has been integrated into the simulator along with improvements to ATC (Air Traffic Control).

The full release notes are available below.

New Content

  • FSX legacy liveries are available on appropriate aircraft: Kenmore, Emerald Gold, Global Freightways, Orbit, Pacifica and World Travel.
  • Contrails are now displayed on the player's aircraft (multiplayer and AI are not supported yet).
  • A new customisation menu in the World map further adjusts the aircraft to match specific real-world aircraft. The changes only affect the next flight and they are not persistent.
  • The empty CG position can be different. Just like on real aircraft, the empty balance can be slightly different.
  • The wear on the fuselage can be increased to get a slightly higher parasitic drag and simulate older aircraft.
  • The maximum angle limits for the elevator, rudder and ailerons can be adjusted to simulate the slight difference that may exist between different real aircraft. Check the Type Certificate Data Sheet (TCDS) Information for real-world aircraft control surface angle limit variation tolerance.
