China Civil UAV Theory Questions — Questions 243–252

① Site annotation: mainly includes takeoff site annotation, landing site annotation, and emergency site annotation, providing the operator with area references for launch, recovery and emergency forced landing. ② Warning annotation: mainly used for annotating key targets in the flight area, such as buildings, no-fly zones, densely populated areas and other areas that may affect flight safety. ③ Mission area annotation: the UAV reconnaissance and surveillance area shall be annotated in advance, mainly including the mission area scope, reconnaissance and surveillance objects, etc.

Study note: with task allocation, choose mission planning. UAV mission planning means formulating flight routes and allocating tasks for UAVs, based on the missions the UAVs must complete, the number of UAVs, and the types of mission payloads carried. For comparison: UAV track planning is the core content of mission planning. It requires comprehensive application of navigation technology, geographic information technology and remote sensing technology to obtain complete, detailed information on the UAV's current flight status and environment, combined with the UAV's own technical characteristics, and following a track planning method, to formulate an optimal or suboptimal route.

The attitude indicator shows the aircraft's current attitude, which is the area the pilot should pay most attention to.

Track planning designs routes at the ground control station and has nothing to do with flight control technology. Rule out B. Track optimization algorithms are involved in track planning, but compared with other 'technologies,' they are not a concept on the same level. Rule out C. Remote sensing technology relates to considering communications planning for task allocation in track planning. A is correct.

Track distance constraints: limit the track length to no more than a preset maximum distance. (Beyond the preset maximum distance, the UAV cannot reach the target and the mission fails.) A fixed target entry direction ensures the UAV approaches the target from a specific angle. (A wrong entry direction means a wrong aerial photography angle, and the mission fails.)

UAV mission planning is an effective way to achieve autonomous navigation and flight control. Memorize the textbook original text directly.

Factors to consider in mission planning include flight environment limits, flight mission requirements, UAV physical limits, and real-time requirements.

Memory logic: what tasks to do (task allocation), how to fly there (track planning), and rehearse the plan several times (simulation demonstration). ① Task allocation function: fully considering the UAV's own performance and the types of payloads carried, coordinating UAV and payload resources across multiple missions and targets to complete assigned missions in the shortest time at the lowest cost. ② Track planning function: on the principles of avoiding restricted risk areas and minimizing fuel consumption, formulating the UAV's flight trajectories for takeoff, landing, approaching monitoring points, monitoring areas, leaving monitoring points, return, emergency flight and other mission processes. ③ Simulation demonstration function: enabling flight simulation demonstration, environmental threat demonstration, and monitoring effect demonstration.

UAV physical limits on flight tracks include minimum turning radius, maximum pitch angle, minimum track segment length, and minimum safe flight altitude.

Because electronic maps deviate from actual geographic positions, calibration is needed before use. Rule out A. Calibrated map files can be saved, so later use can directly load the calibrated map. Rule out C.
