Answer

The reversal of the Earth's magnetic poles

Question 15

How does performing a steep banked turn affect the stall speed of a fixed-wing UAV compared to level flight?

Accepted Answer

The stall speed increases because the wings must produce more lift to counteract the higher load factor

Answer

The stall speed remains exactly the same

Answer

The stall speed decreases, making the drone more stable

Answer

Stall speed only applies to multirotor drones

Question 16

Flying a drone low over a densely packed city on a windy day is risky primarily due to:

Answer

Magnetic interference from streetlights

Answer

A total lack of wind between the buildings

Question 17

What is the primary cause of 'Mechanical Turbulence'?
