Which term best describes a configuration with two straight sections and a flat intermediary landing?

• A. Large Spiral Stairway
• B. Stairway Chairlift
• C. Flat Curve
• D. Installation Sequence

Answer: (C)

The question tests recognizing the standard layout term for an escalator or moving walk that changes direction with a level landing between two straight runs. When you have two straight sections connected by a landing that is at the same elevation (flat) and the path between the straight sections isn’t a simple straight line, this configuration is described as a flat curve. The word “flat” emphasizes the landing is level, while “curve” indicates the overall route changes direction between the straight segments. The other options don’t describe this specific arrangement: a large spiral stairway implies many turns around a central core, a stairway chairlift is a different system, and an installation sequence refers to the order of putting components together.
