Calculation method
Calculation method
Stair width margin (m)
Pitched item horizontal length=Lcosθ+Hsinθ; vertical envelope=Lsinθ+Hcosθ; landing centred turn uses plan diagonal.
Landing centred-turn margin (m)
Pitched item horizontal length=Lcosθ+Hsinθ; vertical envelope=Lsinθ+Hcosθ; landing centred turn uses plan diagonal.
Overhead margin (m)
Pitched item horizontal length=Lcosθ+Hsinθ; vertical envelope=Lsinθ+Hcosθ; landing centred turn uses plan diagonal.
Prescribed maneuver geometric fit (1/0)
Pitched item horizontal length=Lcosθ+Hsinθ; vertical envelope=Lsinθ+Hcosθ; landing centred turn uses plan diagonal.

Assumptions & limits
Assumptions & limits
- Fixed-pitch carry and centred landing turn only. Not a full stair path, lifting or structural safety assessment. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Fixed-pitch carry and centred landing turn only. Not a full stair path, lifting or structural safety assessment.
