Question

With regards to wake turbulence, the vortices of a departing large aircraft will tend to move laterally over the ground at a speed of:

a. 1 to 2 knots
b. 2 to 3 knots
c. 4 to 5 knots
d. More than 10 knots

Answer 1

The vortices of a departing large aircraft will move laterally over the ground at a speed of 1 to 2 knots.

Step-by-step explanation:

The speed at which the vortices of a departing large aircraft will tend to move laterally over the ground is 1 to 2 knots (option a).

These vortices, also known as wake turbulence, are generated as a result of the airflow around the aircraft's wings during takeoff or landing. They consist of swirling patterns of air that can affect other aircraft in their vicinity, especially if they are smaller or lighter.

The lateral movement of these vortices is influenced by factors such as wind speed, aircraft size, and aircraft weight. Generally, the lateral movement is relatively slow, ranging from 1 to 2 knots.
