exemple 75: Leading edge contamination
Under wing contamination. flap contamination. trailing edge contamination.

Question 71-3 : The person who ensures that the drone is serviceable for flight is ?

The pilot.

exemple 79: The pilot
The drone's owner. the builder. the sponsor of the flight.

Question 71-4 : Frost ice or snow on a wing will ?

Increase the stall speed and reduce the rate of climb.

exemple 83: 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 71-5 : The risk of losing visual line of sight of the small rpa is increased when you are operating in ?

In an urban area.

exemple 87: In an urban area
In mountainous terrain. within the boundaries of an aerodrome. periods of darkness.

Question 71-6 : The main risk associated with frost contamination on your remotely piloted aircraft is ?

A lift decrease leading to degrade flight performance.

exemple 91: 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 71-7 : 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 95: 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.

Standard atmosphere.

exemple 99: Standard atmosphere
Metric values and figures. imperial values and figures. extended performance requirements.

Question 71-9 : 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 103: 1 2 3 4
1, 2, 3. 2, 3. 3.

Question 71-10 : Aircraft performance during a steady horizontal turn the stall speed ?
