Stair Flight
A continuous series of steps with no intermediate landings.

a straight flight of concrete stairs
A straight flight of concrete stairs.

As far as regulations go, a quarter landing is considered sufficient to halt a falling person, but the winding turns and spiral stair shown here are not considered enough to halt a fall, so as far as the regulations go the illustrations shown here are considered single flights of stairs.

The important concept here is that though a flight of stairs is mostly in a straight line, it can take any of the forms shown here and also combinations of them.

A flight does not have any landings, and a flight in most jurisdictions and especially with public access is limited to a certain number of steps, so if the design calls for a landing the the stair has to be split into separate flights.

stair flight with three winders
A flight of stairs comprising a straight section and a quarter turn using three winder treads.

a half turn of winders
A flight of stairs comprising a straight section and a half turn using six winder treads.

a spiral stair
A Victorian era cast iron mass produced spiral stair.
