What wind condition prolongs the hazards of wake turbulence on a landing runway for the longest period of time? Light quartering tailwind.
Does wind affect wake turbulence?
The type of weather conditions in which pilots can most expect to encounter wake turbulence are: stable, still/light wind conditions; wind direction down the runway.

What wind condition requires maximum caution with respect to wake turbulence?
THE LIGHT QUARTERING TAILWIND REQUIRES MAXIMUM CAUTION.
Under what conditions can wake turbulence be expected?
Pilots should be alert for wake turbulence when operating:
In the vicinity of aircraft climbing or descending through their altitude. Approximately 10-30 miles after passing 1,000′ below opposite-direction traffic. Approximately 10-30 miles behind and 1,000′ below same-direction traffic.
What causes wake turbulence?
Wake Vortex Turbulence is defined as turbulence which is generated by the passage of an aircraft in flight. It will be generated from the point when the nose landing gear of an aircraft leaves the ground on take off and will cease to be generated when the nose landing gear touches the ground during landing.
What is wake turbulence and how can it be avoided?
When an aircraft is flying, the wingtip vortices produced by the aircraft slowly descend behind the airplane. When the aircraft touches down, the vortices end. By flying your airplane above their flight path, and landing beyond their touchdown point, you’re almost guaranteed to avoid a wake turbulence encounter.
How do meteorological conditions affect wake turbulence?
Under certain meteorological conditions such as stable stratified atmosphere and temperature inversion, the wake vortices have reduced descent speed and decay faster. The longest-lived vortices are observed in non-turbulent and neutrally stratified environments.

What causes wake turbulence quizlet?
Wake turbulence is a phenomenon resulting from the passage of an aircraft through the atmosphere. The term includes vortices, thrust stream turbulence, jet blast, jet wash, propeller wash, and rotor wash both on the ground and in the air.
Which of the following produces the greatest wake turbulence?
The greatest wake turbulence is associated with which aircraft configuration? A. Heavy, clean, fast B. Heavy, dirty, slow C. Heavy, clean, slow | Heavy, clean, slow |

What is wake turbulence category?
Wake turbulence categories of aircraft
They are categorized by a letter in a flight plan L, M, H or J: L = Light = maximum take-off mass < 7000 kilograms (15,000 lb) M = Medium = 7000 kilograms < maximum take-off mass < 136,000 kilograms. H = Heavy = maximum take-off mass >136000 kilograms (300,000 lb)
How fast does wake turbulence descend?
Wake vortices spread laterally away from the aircraft and descend approximately 500 to 900 feet at distances of up to five miles behind it. These vortices tend to descend at approximately 300 to 500 feet per minute during the first 30 seconds.

How common is wake turbulence?
Two words: wake turbulence. The smaller jet had been caught in the vortices generated by the huge A380. Fortunately, pilots actively avoid situations like this one, and wake-turbulence incidents are very rare.
What flying conditions give the worst wake turbulence?
Incident data shows that the greatest potential for a wake vortex incident occurs when a light aircraft is turning from base to final behind a heavy aircraft flying a straight-in approach.
In what flight condition must an aircraft be in order to spin?
In order to enter a spin, an airplane must always first be stalled. Thereafter, the spin is caused when one wing is less stalled than the other wing. In a spin to the left, the right wing is less stalled than the left wing.
What is the force of wind behind an aircraft called that can cause serious damage or injury?
Wind shear is a major hazard for aviation especially when operating at low levels. Even when flying within a layer with a laminar flow and the flight is smooth and uneventful, the sudden crossing of the boundaries between different laminar streams will accelerate the aircraft to a greater or lesser degree.
What does wind shear do?
Wind shear describes how the wind changes speed and/or direction with height. There is almost always some degree of wind shear present within the atmosphere: however, it tends to be much greater across central Illinois during the winter and spring when strong storm systems frequently impact the region.
Why do airline pilots say heavy?
The word “heavy” means a larger aircraft type, with a Maximum Takeoff Weight of 160 tonnes or more. These aircraft create wake turbulence from their wings and require extra separation between following aircraft, and the use of “heavy” reminds other pilots of that fact.
What causes low level wind shear?
Wind Shear From Temperature Inversions
Overnight cooling creates a temperature inversion a few hundred feet above the ground. When coupled with high winds from what is known as the low-level jet stream, this inversion can produce significant wind shear close to the ground.
Do winglets reduce wake turbulence?
Winglets reduce wake turbulence thus minimizing its potential effect on following aircraft. Winglets come in different shapes and sizes with each type performing the same basic drag-reducing function. They have proven to be very effective even when retrofitted to aircraft originally designed in the 1960s.
When departing behind a heavy aircraft the pilot should avoid wake turbulence?
When landing behind a large aircraft, which procedure should be followed for wake turbulence avoidance? Stay well below its final approach flight path and land before its touchdown point. Stay above its final approach flight path and touch down beyond where the larger aircraft landed.

How does wake turbulence vortex circulate?
How does the wake turbulence vortex circulate around each wingtip? Outward, upward, and around each tip.
What are vortices aviation?
Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. One wingtip vortex trails from the tip of each wing. Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.
