Emergency Displacement System (EDS)

Emergency displacement system in action

The Emergency Displacement System (EDS) is usually activated by the TARDIS in situations where the Hostile Action Displacement System would be insufficient to safeguard the capsule. By enabling the localized default setting the operator can also trigger the system with the push of two buttons. When activated, the EDS uses a type of microjump known as a Materialization Flip-Flop. Because this setting has its own logic loop it bypasses most of the guidance systems, resulting in a materialization in a theoretically safe location.

This safe location will take the form of a random 'nearby' point in space in time that could be up to several hundred miles and somewhere between 5 minutes to 500 years from the previous location. However, if the threat pursues the TARDIS into the Vortex, the ship will travel as far through time as necessary to escape from the danger, even if it means violating the noosphere parameters.

Using a Time Safety Jump the EDS can be limited to temporal jumps. By limiting the Flip-Flop to a shift through time only, the operator can
materialize the TARDIS inside a craft that was on a collision course for the capsule. This requires a fair amount of skill from the operator as timing is critical.

While designed to move the TARDIS to random safe location, this system can also be used to take the TARDIS to a random dangerous location by reversing the linearity of the proton flow. Materialization Flip-Flops tend to cause damage to a TARDIS that takes some time to repair and for this reason should only be used in an emergency.
