Which aircraft has the greatest wake turbulence?
Depending on the size of the helicopter, significant wake turbulence can be generated. Helicopter wakes may be of significantly greater strength than those from fixed-wing aircraft of similar weight. The strongest wake turbulence can occur when the helicopter is operating at lower speeds (20 to 50 knots).
In which type of aircraft and in which configuration is wake turbulence most prominent?

What is the greatest aircraft factor that affects the intensity of wake turbulence?
What is the greatest factor that affects the intensity of wake turbulence? Weight. – Proportionately, the intensity and strength of the wake turbulence increase with the weight of the aircraft. – Since the wing needs to support more weight, the greater the amount of lift produced results in greater wake turbulence.
How does an airplane form wake turbulence when landing?
When landing behind a departing larger aircraft it is important to touchdown before the rotation point of that aircraft. During cruise flight, aircraft are typically traveling at a faster speed which requires a smaller angle of attack to achieve level flight, so the wake is reduced.
When is the greatest potential for 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. Light aircraft pilots must use extreme caution and intercept their final approach path above or well behind the heavier aircraft’s path.
How does a winglet affect wake turbulence?
Studies have shown however, that winglets have a negligible effect on wake turbulence generation, particularly with the slower speeds involved during departures and arrivals The vortex strength from an aircraft increases proportionately to an increase in operating weight or a decrease in aircraft speed
How tall does a helicopter have to be to have wake turbulence?
For this reason, aircraft operating greater than 600 metres above the terrain are considered to be at less risk. Helicopters also produce wake turbulence. Helicopter wakes may be of significantly greater strength than those from a fixed wing aircraft of the same weight.
