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. (TV: 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. (TV: The Invisible Enemy)
By using the dimensional stabiliser of the TARDIS, Drax and the Fourth Doctor reduced their own size. (TV: The Armageddon Factor)
The Fifth Doctor asked if there was a problem with the dimensional stabiliser, causing turbulence. (TV: Time-Flight)
- 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. (TV: Planet of Giants)
Behind the scenes
The video game, NOTDWU: Attack of the Graske, referred to the dimensional stabliser in a gameplay mechanic as a yellow lever that helped the player at home fly the TARDIS to 19th century Earth. This same lever was operated by Sarah Jane Smith in TV: Journey's End to assist in returning the Earth from the Medusa Cascade.
As Attack of the Graske involves multiple choices of endings, this wiki does not consider it a valid DWU source.
In Russell T Davies' book The Writer's Tale, the full original draft of the Bad Wolf Bay script in Journey's End has the Tenth Doctor stating that it takes 'thousands of years' to grow a TARDIS. However, Donna uses her newfound Time Lord knowledge enhanced by human intuition to overcome this problem by suggesting: "...if you shatterfry the plasmic shell and modify the dimensional stabiliser to a foldback harmonic of 36.3, you accelerate growth by the power of 59!" Which would presumably enable a TARDIS to grow within a human lifetime. The scene is included as a bonus feature with the Season 4 DVD box set released in November 2008.
