Question 28-1 : A significant part of the loss of wing lift can be attributed to ? [ Professional Yuneec ]

Leading edge contamination

Question 28-2 : The person who ensures that the drone is serviceable for flight is ?

The pilot.

exemple 32: The pilot
The drone's owner. the builder. the sponsor of the flight.

Question 28-3 : Frost ice or snow on a wing will ?

Increase the stall speed and reduce the rate of climb.

exemple 36: Increase the stall speed and reduce the rate of climb
Increase the stall speed but will not affect the rate of climb. decrease the stall speed and reduce the rate of climb. not affect the stall speed or the rate of climb.

Question 28-4 : The risk of losing visual line of sight of the small rpa is increased when you are operating in ?

In an urban area.

exemple 40: In an urban area
In mountainous terrain. within the boundaries of an aerodrome. periods of darkness.

Question 28-5 : The main risk associated with frost contamination on your remotely piloted aircraft is ?

A lift decrease leading to degrade flight performance.

exemple 44: A lift decrease leading to degrade flight performance
The destruction of the onboard electronics. an increase in weight leading to a deterioration in flight performance. an over-stabilization of the drone by the increase of weight.

Question 28-6 : Portable electronic devices at or near the control station are ?

Only allowed if the pilot can confirm that they will not interfere with the command and control link before and during flight.

exemple 48: Only allowed if the pilot can confirm that they will not interfere with the command and control link before and during flight
Only allowed if they are five watts or less in transmission power. only allowed if they are ten watts or less in transmission power. permitted given that cell phones can be used on commercial airplanes.

Question 28-7 : Figures published on aircraft performance capabilities are always related to ?

Standard atmosphere.

exemple 52: Standard atmosphere
Metric values and figures. imperial values and figures. extended performance requirements.

Question 28-8 : Aircraft performance may be seriously affected by frost ice or snow on the wings and control surfaces primarily because of the 1 increase in gross weight2 disruption of smooth airflow3 strong possibility that the control hinges will freeze4 adverse movement of the c of gthe combination ?

1 2 3 4.

exemple 56: 1 2 3 4
1, 2, 3. 2, 3. 3.

Question 28-9 : Aircraft performanceduring a steady horizontal turn the stall speed ?

Increases with the square root of the load factor.

Question 28-10 : Aircraft performancewhich of the following combinations adversely affects take off and initial climb performance ?

High temperature and high relative humidity.

Question 28-11 : For a fixed wing drone airplane type the best angle of climb ?

Permits the largest gain of altitude in a given distance.

Question 28-12 : For a fixed wing drone airplane type the best rate of climb ?

Permits to travel the greatest distance in a given time.

exemple 72: Permits to travel the greatest distance in a given time
Permits the largest gain of altitude in a given distance. is more important for high outside temperatures. is the maximum altitude that can reach your drone.

Question 28-13 : What information message from the aeronautical service will inform about the presence of thunderstorm ?

The aerodrome routine weather reports metar's .

exemple 76: The aerodrome routine weather reports metar's
The aerodrome forecasts (taf) messages. the graphical area forecasts (gfa's) charts. the ground based radar information messages.

Question 28-14 : What weather service is especially helpful in determining the presence of a thunderstorm ?

Aerodrome routine meteorological reports metar's .

exemple 80: Aerodrome routine meteorological reports metar's
Graphical area forecasts (gfa's). ground based radar information. aerodrome forecasts (tafs)

Question 28-15 : If there is unintended contact between an animal and a small rpa the pilot is required to ?

Cease operations until such time as corrective actions have been taken and risk of reoccurrence has been eliminated.

exemple 84: Cease operations until such time as corrective actions have been taken and risk of reoccurrence has been eliminated
Euthanize the animal in a humane way. contact the spca or a wildlife officer. get help for the animal immediately.
