QUESTIONA remote pilot plans to launch at the maximum gross takeoff weight from a high-elevation site on a hot, humid day. What does the Remote Pilot study guide say about this plan?
- AThe maximum gross takeoff weight is always safe when it is not exceeded
- BThe high humidity will offset the effect of the high temperature
- CA reduction in weight before flight may be required
Show the answer and explanation
Correct answer: C. A reduction in weight before flight may be required
- A — incorrect The guide states that the aircraft may not always safely take off with the maximum load under all conditions.
- B — incorrect High humidity adds to, rather than offsets, the conditions that raise density altitude and degrade takeoff and climb performance.
- C — correct The guide says that although a maximum gross takeoff weight may be specified, high elevations, high temperatures and high humidity (high density altitude) may require a reduction in weight before flight.
