Final answer:
When flying under visual conditions, it is important to maintain a safe distance from the aircraft ahead to avoid wake turbulence. Pilots can also use other techniques like flying at a higher altitude or above the preceding aircraft's flight path.
Step-by-step explanation:
When flying under visual conditions, it is important to avoid wake turbulence in order to ensure safety. Wake turbulence is the disturbance in the air left behind by an aircraft as it passes through the air. It can cause a smaller aircraft to lose control if it flies through the wake of a larger aircraft.
To avoid wake turbulence, pilots should maintain a safe distance from the aircraft ahead, especially if it is larger. This distance is commonly known as the 'separation distance' and it varies based on the size and type of aircraft. As a general rule, pilots should strive to stay at least 2 minutes behind a large aircraft on the same flight path.
Additionally, pilots can also use different techniques to minimize the effect of wake turbulence, such as flying at a higher altitude than the preceding aircraft or flying above its flight path.
