Quick Answer: The wind condition that requires maximum caution when avoiding wake turbulence on landing is a?

What wind condition prolongs the hazards of wake turbulence?

What wind condition prolongs the hazards of wake turbulence on a landing runway for the longest period of time? A) Light quartering headwind.

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.

What is proper procedure to avoid wake turbulence?

Avoiding Wake Turbulence During Takeoff

Rotate prior to the point at which the preceding aircraft rotated. Maneuver your aircraft to avoid the flight path of the preceding aircraft.

What is a light quartering tailwind?

Light: in light winds the vortices stay around longer; if the wind is greater than 5 knots then the vortices move out of the way quickly and break up. Quartering: crosswinds blow the vortices across the aircraft’s flight path, which means that if you’re landing next then one vortex might still be over the runway.

Which of the following produces the greatest wake turbulence?

The strongest wake turbulence can occur when the helicopter is operating at lower speeds (20 to 50 knots). Some mid-size or executive-class helicopters produce wake turbulence as strong as that of heavier helicopters.

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.

Why do pilots say heavy?

When a pilot uses the phrase “heavy,” he is reminding ATC that his aircraft is large and requires more separation between it and the aircraft following.

How dangerous is wake turbulence?

However, on some days, the wake can descend more slowly or the trailing airplane can be lower. In these cases, interaction with a wake is to be expected. Wake turbulence is normally not dangerous; there are exceptions to this.

Do Helicopters experience turbulence?

Helicopters ride out turbulence thanks to their sleek bodies and flexible blades- which means passengers won’t feel a thing! If turbulence is severe, we simply do not fly.

Can turbulence flip a plane?

Except that, in all but the rarest circumstances, it’s not. For all intents and purposes, a plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket. Conditions might be annoying and uncomfortable, but the plane is not going to crash.

Which factor has the greatest impact on wake turbulence?

The strength of the wake turbulence is governed by the weight, flight speed, and wingspan of the aircraft. Aircraft weight is the predominant factor. The greatest wake turbulence strength occurs when the generating aircraft is heavy, in a clean-wing configuration, and flying at slow airspeed.

What do pilots mean by 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.

How does tailwind affect landing?

When you’re landing with a tailwind, you have a higher ground speed on touchdown. When pilots land with a higher ground speed, they have a tendency of braking more aggressively than usual. In tricycle gear planes, most of the aircraft’s weight is on the main gear. But that all changes when you land and hit the brakes.

Which aileron positions should a pilot?

Which aileron positions should a pilot generally use when taxiing in strong quartering headwinds? Aileron up on the side from which the wind is blowing. Aileron down on the side from which the wind is blowing. Ailerons neutral.

What does wind shear mean?

Wind shear is defined as a sudden change of wind velocity and/or direction. Windshear may be vertical or horizontal, or a mixture of both types.
