A dimensional stabiliser inside the Doctor's TARDIS. (DW: Attack of the Craske)
The dimensional stabiliser of a TARDIS (specifically the Monk's TARDIS) regulated the outer plasmic shell of the ship in relation to its exterior. By sabotaging the Monk's dimensional stabiliser, the First Doctor made the inside of the Monk's TARDIS the same size as the outside. This meant that the Monk could not squeeze in through the doors of his ship. (DW: The Time Meddler)
In 5000, Professor Marius used the relative dimensional stabiliser of the Doctor's TARDIS to shrink down clones of the Fourth Doctor, Leela and Lowe, and enlarge the Nucleus of the Swarm, bringing it into the macrocosm world. (DW: The Invisible Enemy)
By using the dimensional stabiliser of the Doctor's TARDIS, Drax and the Fourth Doctor reduced their own size. (DW: The Armageddon Factor)
The Fifth Doctor asked if there was a problem with the dimensional stabiliser, causing turbulence. (DW: Time-Flight)
At least after the Last Great Time War, the dimensional stabiliser inside the Doctor's TARDIS was a large device activated by a lever, which helped in flight. (DW: Attack of the Graske)
During the return trip of Earth from the Medusa Cascade in 2009, the dimensional stabiliser was manipulated by former companion Sarah Jane Smith to assist with the flight. (DW: Journey's End)
- On one occasion, space pressure reduced both the interior and the exterior of the Doctor's TARDIS to minute size without affecting the passengers adversely. The space pressure may have affected the ship's dimensional stabiliser, though the First Doctor did not elaborate on the cause of this effect. (DW: Planet of Giants)
