WebThe vortices create air inlet distortions that disrupt temperature sensing and cause mild instability in controlled speed so we need to get rid of them. Likewise when beginning a takeoff roll most pilots bring power up gradually until some airspeed develops then can “punch” it down the runway.

WebWake turbulence can occasionally, under the right conditions, be heard by ground observers. 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. WebTurbulence and Wind Shear Wind shear can be defined as ‘ layers or columns of air, flowing with different velocities (i.e. speed and/or direction) to adjacent layers or columns ’. Wind shear is a major hazard for aviation especially when operating at low levels.
