13 - On the weather map of the flight area, the isobars are close together. What does this mean? There is no difference UAS Latency does not affect aircraft It is the relationship between the frequency and severity of a possible event

17 - If I fly in VLOS, do I have to keep the UAV in sight at all times? Serious malfunctions may occur (up to and including explosion) No particular effect None of the other answers is correct Yes always

18 - Mechanical turbulence is caused by artificial or natural obstacles at the level of the soil: The difference of quota Speed and battery limitations Motor and mass limitations All answers are correct

19 - On a windy day, in an urban environment: A decrease in atmospheric pressure Convection Irradiation Conduct

20 - Clear, sunny day: I must fly with the sun: Up to 50 meters above the lowest structure Wind direction and speed Possible dangerous weather conditions All answers are correct

21 - In which layer of the atmosphere most meteorological phenomena take place? It is the relationship between the frequency and severity of a possible event It is what happens when one does not have sufficient piloting experience None of the other answers is correct It is what occurs when rules are not respected

22 - Read the following observation of the weather. It is the 12th of May: METAR EHEH 011925Z AUTO 30021KT 270V340 9999 SCT055 BKN060 OVC065 09/09 Q1011 NOSIG= What is the status of the cloud cover at 6500 feet? Completely cloudy Mostly cloudy Slightly cloudy Cloudless

23 - What does METAR tell us? Proportional only to the risk of the intended Transaction The wind forecast Rainfall forecast The weather forecast

24 - The subsidence process in meteorology always occurs within: A2 Sub-category covers operations during which flying close to the people will represent a predominant part of the flight, while A3 subcategory concerns operations conducted in an area where the remote pilot reasonably expects that no uninvolved person will be placed in danger from the flight of the UAV There is no substantial difference All other answers are incorrect 900 ft

25 - How many degrees do we use to indicate wind direction? Cannot fly horizontally Land and take off vertically (like a multicopter) Only take off in large open spaces Depends on what is stipulated in the flight manual

26 - Should the battery voltage also be monitored during flight? None of the answers is correct Air pressure Ambient temperature and air pressure Can affect flights of manned aircraft at any altitude

27 - What is the instrument to be used for wind intensity? All 3 other answers are correct. Depends on the situation 3 6 9

28 - Among the factors with the greatest impact on the performance of a UAS are: Depends on the forward speed of the UAV 10 m Lithium ions Lithium-polymer

29 - In a situation of low humidity, a temperature of 15° and high pressure atmospheric: Air humidity and optical illusions Type and cloud cover Brightness type All other answers are correct

30 - Does a body of water or a plowed field give off more heat during the day? Because the electronics could be damaged Because the remote pilot's visibility is greatly reduced All other answers are correct Because the collision sensors may not function properly

31 - In the initial phase of a thunderstorm I can anticipate that my UAV will encounter: Drawing up a checklist so as not to forget any control Starting the mission Contact the nearest Control Tower to check that there is no traffic aeroplane in the area Because the electronics could be damaged

32 - In very cold temperatures, which of the following precipitation freezes immediately after impact? Greater stability Increased flow rate Lower load capacity Lithium ions

33 - Which phenomenon originates during heavy condensation nuclei, winds weak and high humidity? It is indifferent as long as I have had the foresight to wear appropriate sunglasses On the side It must be cancelled It must be paused by leaving the drone hovering until the improvement of visibility

34 - In the presence of wind in an urban setting: Never Dirigible Convertiplane Multirotor

35 - In the case of air currents hitting obstacles or terrain relief, we can speak of a: It is appropriate to arm the UAV but not to take off for a few minutes You should take off at full power It is advisable to leave the UAV hovering for a few minutes None of the answers is correct

36 - In strong winds, a deviation of the UAV from its own trajectory? A sudden change in wind direction A sudden change in air mass temperature A sudden change in wind direction and intensity No, never

37 - An air mass is saturated when: I can safely carry out the mission with UAS while taking into account the fact that I will most likely encounter turbulence I can safely perform the mission with UAS Yes, always over 4 kn Never

38 - What is a cyclone? Can be caused by obstacles at least 120 meters high No, the wind speed is too high to fly Yes, but you have to do it fast because UDP is almost over Yes, but one must pay attention to the variable wind direction

39 - Why is fog dangerous for flying a UAV? SAFETY MANAGEMENT SYSTEM It takes off vertically and then proceeds vertically It takes off horizontally and then proceeds horizontally It takes off horizontally and then proceeds vertically

40 - To get an accurate pre-mission weather picture, the remote pilot must consult: Cost and difficulty of taking measures to reduce or eliminate the risk Time, cost and difficulty of taking steps to reduce or as far as possible elimination of them South West

41 - When there is fog? Yes, but only in special situations e.g. if you have to perform a landing of emergency away from one's position The pilot does not, but the Observer does 50 m 60 m

42 - As the altitude increases, the temperature? Yes, but only after having carried out a new series of experimental tests and having new flight manual drafted No, never Yes, but only to the strict extent necessary for proper performance of the mission Yes, provided that CAA has expressly authorized it

43 - In case of mist or fog: Meteorology has as its ultimate goal the understanding of atmospheric phenomena short-term forecasts, whereas Climatology studies the processes dynamics that change average weather conditions over the long term Inches Eighths Metres

44 - If visibility is less than 2.5 km we are in the presence of: Other aircraft Any flying animals Other people on the ground and other aircraft It goes from the sea to the land at night

45 - A fixed-wing UAV: A body of water Depends on the latitude at which they are located Both equally A plowed field

46 - What are the quantities that characterize the atmosphere and on which the weather phenomena? The possibility of losing sight of the drone is maximum Transport Aerodrome Facilities Terminal Aircraft Fault Terminal Aerodrome Forecast

48 - In the adiabatic expansion of moist air in its upward motion One or more cells Dynamic meteorology All other answers are correct Synoptic meteorology

49 - The term 'mist' means: The identification of risks Prevention of potentially harmful events Analyzing possible risks in order to mitigate them and make them acceptable The possibility of losing visual contact with the drone is very high, but I can however flying based on the anti-collision sensors installed on the UAS

50 - One of the severe risks of flying with UAS is turbulence: Sometimes Yes No, because it only concerns the organization of the operator No
