Wake turbulence can occasionally, under the right conditions, be heard by ground observers. [25] On a still day, the wake turbulence from heavy jets on landing approach can be heard as a dull roar or whistle. This is the strong core of the vortex. If the aircraft produces a weaker vortex, the breakup will sound like tearing a piece of paper.
The hazardous aspects of wingtip vortices are most often discussed in the context of wake turbulence. If a light aircraft immediately follows a heavy aircraft, wake turbulence from the heavy aircraft can roll the light aircraft faster than can be resisted by use of ailerons.
As stated by the U.S. FAA, The pilot has the ultimate responsibility for ensuring appropriate separations and positioning of the aircraft in the terminal area to avoid the wake turbulence created by a preceding aircraft. [1] There are three sets of flight rules under which an aircraft can be flown: Visual Flight Rules (VFR)
Weather at high altitude (storms and clear air turbulence), microbursts at ground level and wake turbulence caused by other aircraft can all be included under the term “turbulance” according ...
In the sport of wakeboarding the wake is used as a jump. The wake is also used to propel a surfer in the sport of wakesurfing. In the sport of water polo, the ball carrier can swim while advancing the ball, propelled ahead with the wake created by alternating armstrokes in crawl stroke, a technique known as dribbling. Furthermore, in the sport ...
Sending aircraft into the wake turbulence of another aircraft at such close intervals could cause unpredictable aerodynamic behavior and loss of aircraft control. More than once, aircraft have crashed on takeoff after encountering such wake turbulence.
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow , which occurs when a fluid flows in parallel layers with no disruption between those layers.
The U.S. FAA lists factors of aircraft upset in the Airplane Upset Recovery Training Aid [1] [2] as follows: . Turbulence causes: . Clear air turbulence; Mountain wave turbulence ...
