They present a risk of bursting in the event of overload
Question 50-2 : An autopilot system operates on the principle of ?
For every action there is an equal and opposite reaction.
Gyroscopic rigidity in space. gyroscopic precession. acceleration and deceleration logarithms.
Question 50-3 : A battery that has been damaged while being transported or in a crash ?
Should be carefully discharged and disposed of as soon as possible.
Question 50-4 : In an inertial measurement unit imu accelerations are measured in relation to the ?
Aircraft axis pitch roll and yaw axis .
An imu consists in a platform attached to the aircraft chassis and which includes gyroscopes and accelerometers the accelerations are measured in a trihedron which is fixed regarding to the aircraft's trihedron pitch roll and yaw axis Direction of the true north. earth's trihedron (x, y, z). absolute space axis (x, y, z).
Question 50-5 : Inertial measurement unit imu accelerometers measure ?
Linear accelerations.
An imu consists in a platform attached to the aircraft chassis and which includes gyroscopes and accelerometers the accelerations are measured in a trihedron which is fixed regarding to the aircraft's trihedron pitch roll and yaw axis Angular accelerations. vertical accelerations. rate of angular accelerations.
Question 50-6 : Inertial measurement unit imu an inertial measurement unit imu includes ?
Accelerometers and gyroscopes.
An imu consists in a platform attached to the aircraft chassis and which includes gyroscopes and accelerometers the accelerations are measured in a trihedron which is fixed regarding to the aircraft's trihedron pitch roll and yaw axis Accelerometers only. gyroscopes only. always a magnetic compass.
Question 50-7 : Above what altitude must all crew members use supplemental oxygen when operating a small remotely piloted aircraft ?
There is no regulatory requirement to use oxygen when operating an rpa.
Question 50-8 : After taking medication for sleep disorders andor nervousness a drone pilot intending to perform a flight must pay attention ?
To the effect they have on reaction time and on the faculties of perception.
To wait 12h after the absorption before flight. the fact that there is no difference between the quality of sleep obtained under the influence of these drugs and that of normal sleep in the absence of medication. to the effect they have on hearing.
Question 50-9 : During an aerial photography work airborne imagery your customer wants additional unprepared views your decision is ?
I finish the first flight as planned i land and will plan the new flight.
I ask the customer for his help in order to perform the requested views. i switch on the gps function to safely perform this new task. i switch to the hovering mode in order to implant the requested new points in the guidance system.
Question 50-10 : Indicate the factor that tends to emphasize the empty field myopia effect in winter ?
The sun in front of the observer causes the details and the relief of the visual field to be lost.
Empty field myopia empty space myopia a condition in which the eyes having nothing specific within the available visual field upon which to focus focus automatically at a range of the order of a few metres ahead detection of objects outside this restricted field of view is delayed and if an object of interest does enter the restricted field of vision the determination of its size or range would be problematic the list below consists of several identified conditions when the eyes often tend to turn back to their natural resting state in visual meteorological conditions vmc when the sky is featureless and visibility is 10 km or more in very dark night with no stimuli outside to focus on in hazy conditions when the optical properties of the atmosphere alter the appearance of aircraft and terrain in bright light and glare when the flight is conducted in very sunny conditions over a cloud layer or the flight course is in the direction of the sun flying over snow covered or desert surfaces with predominantly featureless ground characteristics and over large bodies of waterThe sun behind the observer causes the details and the relief of the visual field to be lost. the steep terrain that blocks the view in the distance. large wooded areas that block the view in the distance.
Question 50-11 : Considering personal conditions no pilot shall operate a small rpa unless they ?
Are fit to perform their duties.
You have to be hydrated and properly fed but also not tired not depressed not under the influence of drug and you don't have to carry on a fire extinguisher or a first aid kit to fly your droneHave been properly fed and hydrated. have a first aid kit available. means of extinguishing any fires that are likely to occur.
Question 50-12 : How many phases does sleep involve including paradoxical sleep ?
5.
There are five phases of sleep usually when you are sleeping you begin at stage 1 and go through each stage until reaching rem sleep and then you begin the cycle againeach complete sleep cycle takes from 90 to 110 minutes your brain acts differently in each stage of sleep in some of the stages your body may make movements but in others your arms and legs will be immobilestage 1 sleep is light sleep you experience a drifting in and out of sleep you can be easily woken up your eye movement and body movements slow down you may experience sudden jerky movement of your legs or other muscles these are known as hypnic myoclonia or myoclonic jerksstage 2 around 50 percent of your time sleeping is spent in stage 2 sleep during this stage eye movement stops and your brain waves a measure of the activity level of the brain become slowerstage 3 is the first stage of deep sleep the brain waves are a combination of slow waves known as delta waves combined with faster waves during stage 3 sleep it can be very difficult to wake someone up if you are woken up during this stage you may feel groggy and disoriented for several minutesstage 4 sleep is the second stage of deep sleep in this stage the brain is making the slow delta waves almost exclusively in this stage it is also very difficult to wake someone up both stages of deep sleep are important for feeling refreshed in the morning if these stages are too short sleep will not feel satisfyingstage 5 rem rapid eye movement sleep is the sleep stage in which dreaming occurs when you enter into rem sleep your breathing becomes fast irregular and shallow your eyes will move rapidly and your muscles become immobile heart rate and blood pressure increase men may develop erections about 20 percent of sleep is rem sleep for adults4. 3. 2.
Question 50-13 : How long after a scuba diving who require decompression stops on the way to the surface is it safe to operate a drone ?
2 h.
In case of non compliance with nitrogen desaturation rules any activity may be dangerous it will be prudent to wait 1 to 2 hours before undertaking a remotely piloted flight to avoid risks of discomfort or simply a decrease in concentration due to the fatigue caused by this dive note that the question is about scuba diving with decompression stops not just snorkeling24 h. without delay. 48 h.
Question 50-14 : With respect to accumulated fatigue ?
Even when performing an easy flight with your drone it can reach an unacceptable level.
It is more difficult to detect than acute fatigue. it can easily be fighted by drinking caffeine. it disappears after at least a 6 hours rest.
