Automatic Emergency Landing
Several events can trigger an Automatic Emergency Landing. If the Navigation or Guidance Systems suffer sudden damage while in flight (such as a Critical Timing Error, or monopole turbulence), if the Main Doors are opened while in the Vortex, if the TARDIS is approaching the boundary of the Time Spiral, if exposed to time spillage with a rating of more then 7 of the Bocca Scale or if the Warp Ellipse Cutout Circuit detects an imminent collision with a vessel in spatial-temporal warp ellipse orbit. Under all these circumstances (and more) a TARDIS will use the coordinate override and the Pause Control to initiate an Automatic Emergency Landing on the "nearest" available safe place - preferably a habitable planet. If no safe place is available some TARDISes have been know to materialize inside themselves (see Space Loop). An Emergency Materialization can be manually activated by pushing a green button on the Master Control Console. This function can be used to get a TARDIS to home in on and arrive near the source of a broadcast signal of some sort.
