FLYF20 progress check A2 Flashcards
According to the 1:1 rule, a UAV must keep:
a horisontal distance to uninvolved persons equal to at least the height above ground.
The symbol shows a warm front, but what color and shapes has a cold front on a weather map?
Blue with triangle shapes
The operator has a responsibility to make sure that all involved persons fully understand the risks associated with a flight. (T/F)
True
If the systems performs a RTH-procedure:
The remote pilot has the ability to take over manually if she/he has communication between the remote control and the unmanned aerial vehicle
Supply of drier air will likely remove the presence of fog? (T/F)
True
4 kg is the maximum weight for an unmanned aerial vehicle within the A2 category, that has a C2 marking (T/F)
True
A line connecting points with the same air pressure, on a weather map, is called?
Isobar
Which of the following processes lowers the dew point temperature of the air?
Condensation (moisture in the air changes from gas to water droplets) by precipiation of dew
The maximum altitude for operations in the open A2 category is:
120 m above ground
You need a liability insurance when flying with an unmanned aerial vehicle above:
20 kg
When the air is unstable (many packages of hot air are formed), the ground surface is rough and the wind speed is high you might experience:
Low level turbulance
How does wind normally change in strength and direction within the boundary layer of the atmosphere?
Increases generally in speed and the direction changes towards a higher degree at a higher altitude
In a hot air mass, you can expect the following:
Cumulonimbus, good visibility (except in the showers) and gusty wind
In general, never fly higher than 120 meters above the ground without a permit. But (when approved by the owner) it is allowed to fly higher than 120 metres within the vicinity of artificial objects at a distance of up to 50 metres from the object and an altitude of 15 metres above the obstacle. (T/F)
True
Larger disc area requires less power for hovering (T/F)
True
It does not affect any system if the unmanned aerial vehicle only has limited or no access to GPS coverage. (T/F)
False
In the event that the operation is performed by more than just the remote pilot, for example together with a sensor operator or observer, it is important that everyone can communicate uninterrupted with each other. (T/F)
True
When air masses diverge mean that they approach each other? (T/F)
False
During flights in category A2, you or your observer should always be able to see the unmanned aerial vehicle and the airspace around it. (T/F)
True
To fly in an active control zone, for example at a height of 100 meters above the ground, you must request permission via ATC in the form of a:
Clearance
Radiation fog (created by the ground cooling the air directly above) is most common when:
The sky is clear and the wind is weak during an autumn evening
If the communication between the remote control and the unmanned aerial vehicle is lost, it’s an advantage to have set:
That the unmanned aerial vehicle should return at an appropriate altitude to the “home point”
What kind of “Drönarkörkort” is required for flying a UAV of a weight of 2 kg at a distance of 100 metres from uninvolved persons?D
A2
In order to be able to carry out a risk assessment, it is necessary to identify possible risks throughout the operation and then methodically try to minimize the probability that it will occur. In addition, plan in advance for and, try to reduce the consequences if it happens anyway. (T/F)
True
If you are surprised by strong winds, it is often a good idea to:
Sink with regard to the surroundings as winds are generally less strong closer to the ground
What factors may affect the flight safety of an operation with unmanned aerial vehicles: (Please note that only one answer is correct)
All the following: Current weather, Other airspace users, human factors such as sleep, food intake, psychology, or physiolofy
Maximum speed when using the low speed mode is:
3 m/s
Propeller guards should be used if possible. (T/F)
True
The purpose of an accident investigation is to find out which person or persons are to blame for the accident. (T/F)
False
