'''OrbitMFD''' is an MFD that comes with the stock installation of Orbiter. It provides a graphical and numerical representation of a ship's orbit.

OrbitMFD is supplied with the stock installation of the Orbiter Spaceflight Simulator as provided by Dr Martin Schweiger and has been a part of the simulator since its inception.

OrbitMFD graphically shows the orbit of the ship in green and if a target is selected, the target's orbit, and a celestial body, typically the body with the most gravitational influence on the ship. Any body in the simulator can be selected to show the relation of the orbit to that body. In addition it will show a number of parameters. Pressing the SEL button on an MFD, OrbitMFD is the first MFD in the menu. The graphics will also display the ascending node with a solid square along the orbit, the descending node with an open square with a dotted line between the two, also the apoapsis with an open circle and periapsis with a solid circle. In addition, in the bottom center of the MFD, 'G' will show the amount of gravitational influence of the reference body (0 to 1.00), and will be green greater than 0.50, yellow less than 0.50.
