Part 107 loading & performance questions

LD-001Under Part 107, the maximum takeoff weight of a small UAS (including payload) must be less than:

LD-002How does adding payload weight to a multirotor drone primarily affect its performance?

LD-005Which of the following best describes "maximum gross weight" for a small UAS?

LD-006When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings will be increased anytime the airplane is

LD-007A stall occurs when the smooth airflow over the unmanned airplane's wing is disrupted and lift decreases. This is caused by

LD-008To ensure that the unmanned aircraft center of gravity (CG) limits are not exceeded, follow the aircraft's

LD-009When a multirotor drone hovers within one rotor diameter of the ground, it experiences "ground effect," which results in:

LD-010What is the primary effect of a forward (nose-heavy) center of gravity on a fixed-wing aircraft or UAS?

LD-011An unmanned aircraft with the center of gravity too far aft is most likely to exhibit which characteristic?

LD-012Which type of drag increases as airspeed increases, and which increases as airspeed decreases?

LD-013What load factor is experienced by an aircraft in a coordinated level turn with 60 degrees of bank?

LD-014How does increased aircraft weight affect stall speed?

LD-015What are the four aerodynamic forces that act on an aircraft in flight?

LD-016According to Bernoulli's Principle, what happens to air pressure as velocity of airflow over a wing increases?

LD-018How does cold temperature affect lithium polymer (LiPo) battery performance in a small UAS?

LD-019A remote pilot is hired for a real estate shoot. The drone's spec sheet shows 28-minute flight time. The mission plan is 22 minutes. On the day of the shoot, it's 96°F and the pilot has mounted a camera gimbal bringing the drone to maximum rated payload. What is the most accurate assessment?

LD-022As density altitude increases, how does aircraft performance change for sUAS?

LD-023Why is it important to verify the loaded center of gravity is within the aircraft's approved CG envelope before flight?

LD-027What is "vortex ring state" (also called "settling with power") and under what conditions is a multirotor most vulnerable to it?

LD-030What does "effective translational lift" (ETL) mean for a rotorcraft or multirotor transitioning to forward flight?

LD-031A remote pilot documents a construction site in Flagstaff, Arizona at 7,000 feet elevation on a July afternoon at 92°F. The drone's spec sheet lists a maximum hover altitude of 13,000 feet under standard atmospheric conditions. Should the pilot assume normal performance?

LD-032A remote pilot in Minnesota is conducting real estate shoots in January at 18°F. Their LiPo batteries are rated for 26-minute flight time and are fully charged. A planned shoot requires approximately 22 minutes of flight. How should the pilot manage this operation?

LD-033A remote pilot mounts a thermal camera 4 inches to the left of center on a drone's payload rail to clear a cable obstruction. During a hover test, the drone tilts noticeably to the left and requires continuous right correction from the flight controller. What is the correct assessment?

LD-034A remote pilot arrives at a job planning to fly a standard RGB camera payload but the client asks for thermal imagery instead. The thermal camera is 180 grams heavier than the RGB camera. The drone's published maximum takeoff weight is 2,100 grams; with the RGB setup it sits at 1,990 grams. What should the pilot verify before accepting the swap?

LD-035A remote pilot's favorite battery is 18 months old with 220 charge cycles. The drone's controller now reports only 22 minutes of flight time from full charge, compared to 28 minutes when the battery was new. A planned survey mission requires 24 minutes of total flight time including return. What is the correct decision?

LD-038A remote pilot's drone is rated by the manufacturer for a maximum operating wind speed of 23 knots. The surface observation at the flight site reports 18 knots gusting to 27 knots. What is the correct pre-flight decision?
