Figure 4 Identification of stair flights — Plan view
Explanatory information for Volume Two:
A flight is the part of a stair that has a continuous slope created by the nosing line of treads. The length of a flight is limited to restrict the distance a person could fall down a stair. Quarter landings , as shown in Figure 4 , are considered sufficient to halt a person’s fall and therefore are considered for the purposes of Volume Two not to be part of the flight .
