UAV-Q0263. Because the loaded electronic map deviates from actual geographic position information during operations, the map must be ________ before use.
Explanation
Study note: with deviation, 'calibrate.'
UAV-Q0264. In a flight mission document, the following shall be specified:
Explanation
Basic Rules of Flight of the People's Republic of China, Article 67: a flight mission document is the basic document permitting flight personnel to conduct transit flights and civil aviation flights. A flight mission document is issued by the head of the aviation unit stationed at the airport or the head of the airline. In a flight mission document, the flight mission, takeoff time, route, altitude, minimum meteorological conditions permitting the PIC to fly, and other relevant matters shall be specified.
UAV-Q0265. Generally speaking, in winter, oil-powered civil UAVs and electric civil UAVs fly ______.
Explanation
Study note: oil longer, electric shorter. Winter flight endurance performance of oil-powered and electric civil UAVs is mainly affected by power system characteristics and ambient temperature. Oil-powered UAVs: in low temperatures, air density increases, engine intake air increases, combustion efficiency may improve, and endurance increases. Electric UAVs: lithium battery chemical reaction rates slow as temperature drops; at low temperatures, battery internal resistance increases and discharge efficiency decreases, so endurance drops significantly.
