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

How does a low-level temperature inversion affect local weather and visibility near the ground?

Accepted Answer

It acts like a lid, trapping dust, smoke, smog, and moisture near the surface, often leading to very poor visibility and hazy conditions

Answer

It creates violent thunderstorms

Answer

It clears the air instantly, providing perfect visibility

Answer

It causes the wind to double in speed

Question 3

A remote pilot is conducting a mapping mission, moving from a high-pressure area to a low-pressure area. If they do not recalibrate the barometric sensor, what risk do they face regarding the displayed altitude?

Accepted Answer

The altimeter will display a value higher than the actual altitude, potentially leading the pilot to descend dangerously into ground obstacles

Answer

The altimeter will indicate a lower altitude than actual, leading the drone to fly too high into controlled airspace

Answer

The drone will lose its GPS signal due to the change in atmospheric density

Answer

The battery will drain faster because of the reduced pressure

Question 4

When checking space weather, what does a Kp-index of 0 to 1 indicate?

Accepted Answer

Extremely calm space weather conditions; optimal for reliable GNSS/GPS reception and compass accuracy

Answer

A severe geomagnetic storm; flying is not recommended

Answer

Total loss of GNSS satellites

Answer

A hurricane is approaching

Question 5

A 'Continental Tropical' (cT) air mass is typically:

Accepted Answer

Hot and dry, often originating over desert regions

Answer

Cold and moist

Answer

Warm and extremely humid

Answer

Freezing and dry

Question 6

What is a 'Stationary Front'?

Accepted Answer

A boundary between two different air masses where neither is strong enough to replace the other, resulting in very little movement

Answer

A front moving faster than 50 knots

Answer

A thunderstorm that stays in one place

Answer

A solid wall of fog

Question 7

Due to the pressure gradient force, air naturally flows:

Accepted Answer

From areas of high pressure to areas of low pressure

Answer

From areas of low pressure to areas of high pressure

Answer

Directly towards the equator at all times

Answer

Only upwards

Question 8

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 9

In a METAR report, what does the weather code 'SN' indicate?

Accepted Answer

Snow

Answer

Sandstorm

Answer

Squall line

Answer

Smoke

Question 10

How does surface friction affect the wind near the ground compared to the 'geostrophic wind' at higher altitudes?

Accepted Answer

It slows the wind down and causes it to blow slightly across the isobars toward areas of lower pressure

Answer

It speeds the wind up and makes it blow parallel to the isobars

Answer

It has no effect on wind direction or speed

Answer

It forces the wind to blow strictly vertically
