Flight performance and planning - EASA Drone License A2

Question 1

What is the primary factor you must evaluate to determine the 'Ground Risk' of your operation?

Accepted Answer

The density of uninvolved people in the overflown area and the potential for the drone to impact them in case of a failure

Answer

The presence of other drones in the same airspace

Answer

The softness of the grass in the landing zone

Answer

The radio frequency used by the remote controller

Question 2

What is the primary aerodynamic function of the wing on a fixed-wing UAV?

Accepted Answer

To generate lift by creating a pressure difference (lower pressure above, higher pressure below) as air flows over its airfoil shape during forward motion

Answer

To generate vertical thrust while hovering

Answer

To store the battery and electronics

Answer

To act as a physical bumper against obstacles

Question 3

When the low-speed mode is activated on a C2 drone, what is the maximum permitted speed according to EASA standards?

Accepted Answer

3 m/s

Answer

1 m/s

Answer

5 m/s

Answer

10 m/s

Question 4

What is the function of the Flight Controller in a drone?

Accepted Answer

It acts as the 'brain' of the drone, processing inputs from the receiver and sensors (IMU, GPS) to send appropriate commands to the ESCs and motors to maintain stabilized flight

Answer

It regulates the temperature of the battery

Answer

It compresses the video files for storage

Answer

It connects the drone's Wi-Fi to the internet

Question 5

When flying a drone over large bodies of water, what visual illusion is a pilot most susceptible to?

Accepted Answer

Loss of depth perception and altitude estimation due to the lack of distinct visual references on the surface

Answer

The drone appearing to spin backwards

Answer

The sun appearing to set faster than normal

Answer

Color blindness causing red and green lights to merge

Question 6

If you are flying a C2 class drone in the A2 subcategory and an assembly of people suddenly forms within your flight area, what must you do?

Accepted Answer

Immediately interrupt the operation and safely fly the drone away from the assembly

Answer

Activate the low-speed mode and continue flying directly above them

Answer

Turn off the drone's motors to force an immediate landing in the crowd

Answer

Ignore the crowd if your drone weighs less than 4 kg

Question 7

When working with a Visual Observer (VO), 'closed-loop communication' means:

Accepted Answer

The VO sends a message, and the pilot verbally repeats or confirms it to ensure it was understood correctly

Answer

Using a secret code to speak

Answer

Only communicating via text message

Answer

Talking while standing in a circle

Question 8

In a quadcopter, why do two propellers spin clockwise and two counter-clockwise?

Accepted Answer

To balance the aerodynamic torque; if they all spun the same way, the drone would spin uncontrollably around its vertical axis

Answer

To create a gyroscopic effect that prevents the drone from ascending too fast

Answer

To allow the drone to fly upside down

Answer

Because the motors are wired in series to the battery

Question 9

A UAS operating in the Open category with a C2 class identification label must be equipped with:

Accepted Answer

A selectable low-speed mode that limits the maximum speed to 3 m/s

Answer

A deployable airbag system

Answer

An internal combustion engine

Answer

A secondary flight controller for redundancy

Question 10

What is the primary role of a Visual Observer (VO) during a drone flight?

Accepted Answer

To maintain unaided visual contact with the drone and assist the pilot in safely scanning the airspace

Answer

To take over manual control of the drone if the pilot is distracted

Answer

To talk to bystanders and explain the purpose of the mission

Answer

To monitor the live video feed on a separate tablet
