From what area does the wind blow? from a lower pressure area to a higher pressure area. from a higher pressure area to a lower pressure area. it varies, depending on wind force. we are unable to determine this.
How does flying at low temperatures affect battery life? is extends the battery life. it has no effect on battery life. it shortens the battery life. battery life is not affected by the ambient temperature.
UAV inspection does NOT involve: checking the condition of the propellers. checking whether the battery is sufficiently charged. checking of the optical sensors. checking of the airspace traffic.

Zero degrees Celsius corresponds to 200,12 K. 250 K 273,15 K. 335,73 K.
What is a high Kp index? >2 >3. >4. >5.
When checking the weather conditions, we consider: the Kp index. precipitation. wind direction. the presence of a rainbow.
The average vertical air temperature gradient at 100m is: 0,15︒C. 0,35︒C. 0,65︒C. 0,75︒C.
The air temperature in the troposphere drops to: -20︒C. -35︒C -44︒C. -56︒C.
Demagnetization of motors occurs when their temperature reaches: 50︒C 65︒C. 80︒C 90︒C.
What is the pressure at an altitude of 0 m AMSL? 754,24 hPa. 869,34 hPa. 946,56 hPa. 1013,25 hPa.
Indicate the false sentence. Center of gravity: is the point at which the forces acting on an aircraft vehicle balance each other. has no effect on aircraft’s stability. must be within the specified limits established by the manufacturer. is found in different places, depending on the type of aircraft.
The area used for ground risk assessment consists of: flight geography area. ground risk buffer air risk buffer. adjacent airspace.
During a multi-rotor take-off, we firstly switch on: the transmitter. the receiver. the order does not matter. it depends on the type of the multi-rotor.
According to the International Standard Atmosphere (ISA), at 0 m AMSL the temperature is 0︒C 5︒C. 10︒C 15︒C.
Water boils at: 60︒C 80︒C. 100︒C. 120︒C.
1 standard atmosphere is: 1013,15 Pa. 1013,25 Pa 740 mm Hg 670 mm Hg.
What happens to pressure as the tropospheric altitude increases? it increases. there is no change. it decreases we are unable to determine what the relationship is.
QNH is the pressure with respect to: mean sea level. International Standard Atmosphere. local pressure at a given airport. value of 1000,15 hPa.
8 m/s corresponds to: 3,6 km/h. 7,2 km/h. 25,2 km/h. 28,8 km/h.
2 kts is equal to: 0,28 km/h. 0,514 km/h. 1,852 km/h. 3,704 km/h.
When flying in fog, we have: a better signal between the transmitter and the receiver. a worse signal between the transmitter and the receiver. high air humidity. fog has no impact on our signal.
MTOM is: maximum payload capacity. unladen weight of the UAV. mass of battery. maximum take-off mass.
Choose the wrong answer. Propellers mounted on a drone: rotate clockwise and counterclockwise. produce the necessary lift. can be chipped; their condition does not matter for the safety of the operation affect the performance of the UAV.
In the engines that are usually used in UAVs, which part of the engine rotates? the outer part of the rotor the inner part of the rotor. both rotate simultaneously. none of them rotate.
Before take-off, it is compulsory to: check the weather conditions. check the airspace traffic. perform an UAV inspection. submit your flight details using DroneRadar or FIS.
