# Stall-speed screening
# Scope: Level flight stall speed at supplied maximum lift coefficient.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 2 kg
area = 0.5 m^2
density = 1.225 kg/m^3
maximumLift = 1.2
gravity = 9.81 m/s^2

stallSpeed := sqrt(2*mass*gravity/(density*area*maximumLift)) [m/s]

check stall speed budget: stallSpeed <= 9 m/s

scenario alternative: mass = 1.6 kg
