Meteorology - EASA Drone License A2

Question 1

When assessing the weather for a drone flight, the remote pilot's responsibility is to:

Accepted Answer

Obtain forecasts (METAR/TAF/Apps) during pre-flight planning and continuously monitor the real-time weather conditions visually during the entire operation

Answer

Check the weather once in the morning and ignore it thereafter

Answer

Only check the weather if flying above 100 metres

Answer

Rely entirely on the drone's internal barometer to warn them of bad weather

Question 2

If you set your altimeter to 'QNE' (1013.25 hPa), what are you measuring?

Accepted Answer

Pressure Altitude (Flight Level), used primarily by aircraft cruising at higher altitudes to ensure safe vertical separation

Answer

True Altitude (Height above mean sea level)

Answer

Absolute Altitude (Height above the ground)

Answer

Density Altitude

Question 3

How does 'Advection Fog' typically form?

Accepted Answer

When moist, warm air is blown horizontally over a colder surface (like cold water or snow) and cools to its dew point

Answer

When a thunderstorm collapses

Answer

By the rapid heating of a concrete runway

Answer

Only at altitudes above 10,000 feet

Question 4

When wind flows through a narrow mountain valley or a dense group of tall buildings, its speed typically increases. What is this called?

Accepted Answer

The Funneling (or Venturi) Effect

Answer

The Coriolis Effect

Answer

The Thermal Inversion Effect

Answer

The Ground Effect

Question 5

In aviation, what does 'RVR' stand for?

Accepted Answer

Runway Visual Range; the horizontal distance a pilot on the centre line of a runway can see the runway surface markings or lights

Answer

Radar Vector Routing

Answer

Relative Velocity Ratio

Answer

Rapid Vertical Rise

Question 6

What is a 'Rotor Cloud'?

Accepted Answer

A turbulent, rolling cloud found at the lower levels of a mountain wave system, indicating extreme, hazardous turbulence

Answer

A cloud created by the spinning rotors of a heavy drone

Answer

A harmless, flat cloud found over the ocean

Answer

A cloud formed strictly by industrial pollution

Question 7

What causes 'Steam Fog'?

Accepted Answer

Very cold, dry air moving over much warmer water, causing rapid evapouration and immediate condensation

Answer

Warm air moving over a cold snowpack

Answer

Pollution trapped in a city by an inversion layer

Answer

A sudden drop in barometric pressure

Question 8

In a METAR report, what does the code 'DZ' mean?

Accepted Answer

Drizzle (very fine, closely spaced water droplets falling from a cloud)

Answer

Dust storm

Answer

Danger Zone

Answer

Dense Fog

Question 9

On a weather map, what are 'Isobars'?

Accepted Answer

Lines connecting points of equal atmospheric pressure

Answer

Lines connecting points of equal temperature

Answer

Lines indicating the boundaries of controlled airspace

Answer

Lines tracking the path of a hurricane

Question 10

In a TAF forecast, what does 'PROB40' indicate?

Accepted Answer

There is a 40% probability of the forecasted weather conditions occurring

Answer

Visibility will be 40 miles

Answer

The temperature will reach 40 °C

Answer

Wind will blow exactly at 40 knots
