Which combination is most unfavorable for sUAS performance?

• A.Low gross weight on a cool day at low elevation
• B.High gross weight on a cool day at low elevation
• C.High gross weight on a hot day at high elevation

Why

High weight raises power demand at the same time that high density altitude reduces motor and propeller effectiveness. Together they leave the smallest climb and hover margin.
