# Wing loading
# Scope: Aircraft weight per wing area.
# 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
gravity = 9.81 m/s^2

loading := mass*gravity/area [N/m^2]

check wing loading budget: loading <= 50 N/m^2

scenario alternative: mass = 1.6 kg
