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)

Daleks freely hovered throughout the Dalek Flagship. (TV: Bad Wolf) The Emperor's Personal Guard hovered in a stationary position around the Dalek Emperor. In 200,100, thousands of Daleks flew through space to the Game Station. (TV: The Parting of the Ways)

The Cult of Skaro took flight with the Genesis Ark as they disembarked from the Void Ship into the sphere chamber of Torchwood Tower in 2007, leading to the Battle of Canary Wharf. (TV: Army of Ghosts) Fighting their way to Torchwood One's artefact room, the four Daleks, having overriden the roof mechanism, elevated outside of Torchwood Tower. With a minimum area of thirty square miles, the Genesis Ark was opened, unleashing the millions of Daleks imprisoned within into the sky around Canary Wharf. Proceeding to spread across Earth, the Daleks attacked humans and invading parallel universe Cybermen alike. When the tenth Doctor and Rose Tyler opened the Void, the void stuff-contaminated Daleks were sucked back into the breach en masse along with the Genesis Ark. Dalek Sec, in a stationary hover position, escaped using an emergency temporal shift (TV: Doomsday) along with the rest of the Cult. (TV: Daleks in Manhattan)

In 1930, two members of the Cult of Skaro launched an aerial attack on Hooverville in New York, exterminating Solomon when he attempted to reason with them. When the irate Tenth Doctor attempted to goad the Daleks into killing him next, Dalek Sec ordered them to stop and bring him back to their base. (TV: Evolution of the Daleks)

Numerous Daleks took flight during the invasion of Earth in 2009, most notably during the attack on the aircraft carrier Valiant. (TV: The Stolen Earth) Within the Crucible, the Daleks flew freely before the New Dalek Empire was destroyed by the Meta-Crisis Tenth Doctor, resulting in Daleks exploding en masse while in hover position.
