Question 1 of 12
A small UA's maximum gross takeoff weight is specified by the manufacturer. According to the Remote Pilot Study Guide, which statement about this limit is correct?
Why: The Remote Pilot Study Guide states, "Although a maximum gross takeoff weight may be specified, the aircraft may not always safely take off with this load under all conditions. Conditions that affect takeoff and climb performance, such as high elevations, high air temperatures, and high humidity (high density altitudes) may require a reduction in weight before flight is attempted."
- Treats the published maximum gross takeoff weight as a guarantee of safe takeoff under any condition, when high density altitude from elevation, heat, or humidity can require a lower weight for that same takeoff to be safe.
- Misreads maximum gross takeoff weight as a payload-only limit; it is a limit on the aircraft's total weight, including its own structure, battery, and any payload.
