# Drone endurance estimate
# Scope: Constant hover electrical power and usable battery energy.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

energy = 100 Wh
usable = 0.8
hoverPower = 300 W

duration := energy*usable/hoverPower [s]

check endurance target: duration >= 900.0 s

scenario alternative: energy = 80 Wh
