Which of the following best describes "maximum gross weight" for a small UAS?
AThe weight of the aircraft without any payload or battery
BThe maximum permissible weight of the aircraft including all components, payload, and fuel/battery at takeoff✓
CThe weight of the heaviest payload the aircraft is certified to carry
Why →Maximum gross weight (also called maximum takeoff weight or MTOW) is the maximum total weight at which the aircraft may safely operate. This includes the airframe, motors, battery, camera, gimbal, and any other attached payload. Exceeding it risks structural failure and degraded controllability.
Field note →For DJI Mavic-series drones, maximum gross weight is typically listed in the manufacturer's specs. When you add an aftermarket payload (ND filters, external microphone, etc.) to a drone already at near-max weight, you may exceed MTOW without realizing it.
