AVIATION & AERONAUTIC CALCULATOR
Wake Turbulence Decay
A precise tool.
What is the Wake Turbulence Decay & How does it work?
Wake turbulence is a significant concern in aviation, especially during takeoffs and landings. The decay of wake turbulence depends on various factors such as the aircraft category, weight, and atmospheric conditions.
The decay time of wake turbulence can be estimated using empirical models that consider the aircraft’s maximum takeoff weight (MTOW) and its category. Different categories of aircraft have different wake vortex characteristics.
t_{decay} = frac{C}{V_{airspeed}} cdot left(frac{W_{MTOW}}{1000}right)^{alpha}
t_{decay} = decay time in minutes, C = category constant, V_{airspeed} = airspeed in knots, W_{MTOW} = maximum takeoff weight in kg, alpha = exponent based on aircraft category

Frequently Asked Questions
How does aircraft weight affect wake turbulence decay?
Heavier aircraft produce stronger wake vortices that decay more slowly.
What is the formula used to estimate wake turbulence decay time?
The decay time is estimated using t_{decay} = frac{C}{V_{airspeed}} cdot left(frac{W_{MTOW}}{1000}right)^{0.6}, where C is a category-specific constant.
Why is wake turbulence decay important in aviation?
Understanding wake turbulence decay helps pilots maintain safe distances between aircraft during takeoffs and landings.
How do atmospheric conditions affect wake turbulence decay?
Stronger winds can accelerate the decay of wake vortices, while calm conditions slow it down.
What are the categories of aircraft for wake turbulence calculations?
Aircraft are typically categorized as Heavy, Medium, or Light based on their maximum takeoff weight (MTOW).
Can this calculator be used for all types of aircraft?
Yes, it can be used for various aircraft types by selecting the appropriate category and inputting the MTOW.
How long does wake turbulence typically last after an aircraft has passed?
Wake turbulence can persist from 1 to several minutes depending on the aircraft size and atmospheric conditions.
