What is wake turbulence and when is it the strongest?
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 decides the strength of the wake turbulence?
Air from below the wing is drawn around the wingtip into the region above the wing by the lower pressure above the wing, causing a vortex to trail from each wingtip. The strength of wingtip vortices is determined primarily by the weight and airspeed of the aircraft.
What makes wake turbulence worse?
Weight, speed, wingspan, and shape of the generating aircraft’s wing all govern the strength of the vortex. Since the turbulence from a “dirty” aircraft configuration hastens wake decay, the greatest vortex strength occurs when the generating aircraft is HEAVY, CLEAN, and SLOW.
Why does the greatest vortex strength occur when the generating airplane is heavy slow and clean?
a. Terminal Area. The strength of the vortex is governed by the weight, speed, and wing shape and span of the generating aircraft. The greatest vortex strength occurs when the generating aircraft is heavy-slow-clean since the turbulence from a “dirty” aircraft configuration hastens wake decay.
What does wake turbulence look like?
“The smoke-like appearance is the result of compressing gas into solid (moist air into water vapor),” commerical airline pilot Chris Cooke tells Travel + Leisure. “The more relative humidity there is, the more vapor you’ll see. In most circumstances, wake turbulence and wingtip vortices are invisible to the naked eye.
What is the only thing known to cause wake turbulence to dissipate?
According to the FAA, “a wind speed of 10 knots causes the vortices to drift at about 1,000 feet in a minute in the wind direction.” So after you lift off, simply maneuver your aircraft upwind to stay clear of the wake turbulence.
What are wing tip vortices wake turbulence )? With which aircraft are they greatest describe the proper Avoidance?
Avoiding Wake Turbulence Wingtip vortices are greatest when the generating aircraft is “heavy, clean, and slow.” This condition is most commonly encountered during approaches or departures because an aircraft’s AOA is at the highest to produce the lift necessary to land or take off.
What is 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 statement concerning wing tip vortices is false?
7.11 Which statement concerning wing tip vortices is false? Vortices normally settle below and behind the aircraft. With a light cross wind, one vortex can remain stationary over the ground for some time. Lateral movement of vortices, even in a no wind condition, may place a vortex core over a parallel runway.
