Hover position
Hover position was the Dalek act of ascension. (COMIC: The Penta Ray Factor) Achieved by the base unit of the Dalek motor casing, it allowed individual Daleks to take flight without the use of a hoverbout. Much like how the Daleks fired their gunsticks after exclaiming "exterminate!", a Dalek would generally exclaim "elevate!" before taking flight. (TV: Dalek)
History
During the Shoreditch Incident of 1963, an Imperial Dalek ascended the stairs of the Coal Hill cellar to pursue the Seventh Doctor. (TV: Remembrance of the Daleks)
At GeoComTex in 2012, a Dalek named "Metaltron" seemingly found itself at an impasse when faced with a flight of stairs that Rose Tyler, Adam Mitchell and De Maggio had ascended, with Adam mocking its plight. The Dalek, however, soon began to elevate up the stairs, leaving De Maggio to cover Rose and Adam's escape at the cost of her life. (TV: Dalek)
