Key Takeaways

Star Citizen's flight model aims to simulate the physics of spaceflight and space ships.

  • Correct application of thrust at the places where thrusters are attached to the ship
  • Inertia, mass changes and counter thrust are very necessary
  • Ship & component damage affects flight
  • Designed to offer a great PVP experience
  • Simulates the physics that would involve controlling and moving a ship in space with no short cuts
  • Star Citizen will be controller agnostic
  • Intelligent Flight Control Systems (IFCS)

Current Status Of The Flight Model

As of Alpha 3.7 the Flight New Model is testable. Ships now handle differently and there have even been changes to grav lev vehicles like the Drake Dragonfly.

Status: The New Flight Model was released for testing in Alpha 3.5 in April 2019. As the game (especially Squadron 42) comes closer to release, the flight model must be refined and heavily tested. This could be the start of the final refinement process in flight combat and handling.

Check the November 2019 Star Citizen & Squadron 42 Progress Report for more info.




The Star Citizen flight model continues to improve and be refined which is required for Squadron 42 release.

"This level of realism was necessary in order to deliver a flight control system that could be fully integrated with and influenced by the environment, damage states, changing mass distribution, power allocation, thruster placement, etc. IFCS is an emergent system, and therefore may be imperfect at times. But this mimics reality.

And finally, great effort has been made to limit spacecraft control to only the command pathways provided by IFCS. No player, AI or even IFCS itself will ever modify the position, velocity, rotation or rotational velocity of a ship directly, with the exception of initialization and network correction. This guarantees that all spacecraft control is consistent and the game will never have an unfair advantage over a player."
