49 During GNSS loss, a drone's estimated horizontal position initially remains smooth but gradually diverges from its true position. Which explanation and mitigation are most technically sound?

50 One brushless motor repeatedly loses synchronization only during rapid throttle increases. The battery voltage remains normal, the propeller is undamaged, and the motor windings pass continuity tests. Which component is the primary suspect?

51 A drone uses a nominal , battery. Only of nominal energy is usable, and average electrical power consumption is . Ignoring voltage variation, what is the estimated endurance?

52 Why can a conventional hexacopter sometimes maintain controlled flight after losing one motor, while a conventional quadcopter generally cannot?

53 A drone's yaw estimate changes whenever throttle increases, although its actual heading remains fixed. The magnetometer is mounted beside the battery power leads. What is the best corrective action?

54 A mission requires mapping a linear pipeline, efficient cruise, and no prolonged hovering. Launch and recovery areas are available at both ends. Which aircraft class is generally best suited?

55 An aircraft takes off vertically using powered rotors, transitions to wing-borne forward flight, and lands vertically. Which classification most accurately captures its configuration?

56 An electrically powered quadcopter can fly either pilot-commanded routes or approved automatic missions. Which statement correctly applies drone classification principles?
