Question 6

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

Question 7

On a synoptic weather chart, what do closely spaced isobars indicate?

Accepted Answer

A strong pressure gradient, which results in high wind speeds

Answer

An area of heavy snowfall

Answer

A region completely free of turbulence

Question 8

How does flying a multirotor at a high 'Density Altitude' affect the battery's endurance?

Accepted Answer

The thinner air forces the motors to spin faster to generate the same lift, which draws more current and decreases battery endurance

Answer

It greatly increases the endurance

Answer

It has no effect on the battery

Answer

It causes the battery to freeze

Question 9

Due to the pressure gradient force, air naturally flows:

Answer

From areas of low pressure to areas of high pressure

Answer

Directly towards the equator at all times

Answer

Only upwards

Question 10

Above the friction layer, the 'geostrophic wind' flows:

Accepted Answer

Parallel to the isobars, balancing the pressure gradient force and the Coriolis force

Answer

Perpendicular to the isobars

Answer

Straight up into the stratosphere

Answer

In a perfect circle around the equator

Question 11

If an operator uses an automated mapping software to fly the drone in a grid pattern, what is the remote pilot's responsibility?

Accepted Answer

To continuously monitor the flight in VLOS, scan the airspace, and immediately take manual control if an emergency or conflict arises

Answer

To take a break and ignore the drone until the mission is finished

Answer

To transfer liability to the software manufacturer

Answer

To fly a second drone simultaneously

Question 12

What is 'Buys Ballot's Law' regarding wind and pressure?

Accepted Answer

In the Northern Hemisphere, if you stand with your back to the wind, the area of lower pressure will be to your left

Answer

Wind speed doubles for every 1000 feet of altitude

Answer

Wind always blows directly from South to North

Answer

Hot air is heavier than cold air

Question 13

If a remote pilot modifies a C2 class drone with heavy, non-approved aftermarket parts, what is the regulatory consequence?

Accepted Answer

The modification may invalidate the C2 class mark, potentially forcing the drone to be operated under the more restrictive A3 subcategory rules

Answer

The drone is automatically upgraded to a C3 class

Answer

There are no consequences as long as the MTOM remains under 25 kg

Answer

The drone can only be flown indoors

Question 14

What does a 'Lithium fire' (caused by a punctured LiPo battery) require for safe containment?

Accepted Answer

A Class D fire extinguisher or covering it completely with sand, as lithium fires burn extremely hot and react dangerously with water

Answer

A standard splash of water

Answer

Blowing on it with a fan

Answer

Covering it with dry leaves

Question 15

In a TAF (Terminal Aerodrome Forecast), what does the abbreviation 'BECMG' signify?

Accepted Answer

Becoming; it indicates a regular or irregular change to the forecasted weather conditions, expected to take place over a period of time (usually about 2 hours)

Answer

A completely clear sky

Answer

A sudden, immediate emergency

Answer

Below Minimum Cloud Grade

Question 16

Under what specific conditions does 'Upslope Fog' form, and why is it a significant hazard for drone pilots in hilly terrain?

Accepted Answer

It forms when moist, stable air is forced up rising terrain by the wind and cools adiabatically; it can persist even with strong winds, unlike radiation fog

Answer

It is caused by the sun heating the surface too quickly, creating a steam-like effect

Answer

It forms only in urban areas due to the high density of buildings and smog

Answer

It is formed by the cooling of the Earth's surface during a completely calm, clear night
