The square indicator shows where you need to point your craft at if you were exactly following the predicted trajectory Go back in flight view, and notice the two new indicators on the nav ball White is the trajectory in space, red is the trajectory in atmosphere, the red cross is your impact point (that takes the body rotation into account to show the impact point on the terrain, this is useful both for bodies with and without atmosphere)Ĭlick on the Trajectories icon in the stock KSP toolbar (or Blizzy's toolbar if it's installed) to display the main UIĬlick 'Display trajectory' to toggle it on/offĬlick 'complete' to toggle display of the complete trajectory (including parts where it is superimposed with the stock KSP trajectory)Īdjust your velocity so that the red cross is located where you want to goĬlick 'Set current impact as target' to enable the green crossĪlternatively, there is a button to set the target on the KSC (works on Kerbin only obviously), or you can enter longitude/latitude This is it trajectory display is enabled by default, you have nothing else to do Keep in mind that this software comes without warranty of any kind, and in particular that it may or may not help you survive, reach a specific target, or anything at all. Plan Aerobraking maneuvers that can, for example, put you on intersection trajectory with another body (see point 1 about what you can do from there) Works with the stock aerodynamic model, and with Ferram Aerospace Research ( FAR).Ĭhoose precisely the location where you'll crash. The mod displays trajectory predictions, accounting for atmospheric drag and lift. Parachutes are not simulated (that's usually not a problem if you open it near the ground) It's not possible to predict a trajectory for a future stage. We know this is a highly requested feature, but unless we duplicate big parts of the KSP-internal code, we are limited to simulating the current state of the vessel.If the predicted trajectory seems inaccurate, check that you set the correct orientation in the Descent profile (or checked Prograde or Retrograde), and that you keep that orientation all the time

If you see weird spirals or other crazy lines everywhere, double-check you didn't enable 'body-fixed mode' by mistake Before posting feature requests or bug reports, please read the FAQ.
