A straight run of stairs is known as what?

A straight run of stairs is referred to as a flight. This terminology is used in construction and architectural design to describe a series of steps that extends from one landing to another without any change in direction. A flight can consist of any number of steps and is crucial for the overall function and design of a staircase.

In contrast, a staircase encompasses the entire structure that includes flights of stairs, landings, and any other components. A runway generally refers to a path designed for aircraft or vehicles and is not applicable to stairs. A landing refers specifically to the flat area at the top or bottom of a flight of stairs, serving as a transition point between different levels, but it does not define the straight run of stairs itself. Understanding these terms is essential for anyone involved in building and construction to ensure clarity in design and communication.
