The Velocity In Turn calculation determines the turning speed of an aircraft on a taxiway based on the radius of the curve. This calculation is essential for aircraft maneuvering and is referenced to a standard rate turn, also known as a rate one turn (ROT).
The calculator uses the formula:
Where:
Explanation: The formula calculates the appropriate turning speed based on the square root of the taxiway radius, ensuring safe and efficient aircraft maneuvering.
Details: Accurate turning speed calculation is crucial for aircraft safety during taxi operations, preventing excessive lateral forces, and ensuring smooth navigation through curved taxiways.
Tips: Enter the radius of the curve for the taxiway in meters. The value must be valid (radius > 0).
Q1: Why is the turning speed calculated this way?
A: The formula is derived from standard aircraft maneuvering principles and ensures that the aircraft maintains a safe and controlled turn based on the taxiway geometry.
Q2: What are typical values for taxiway radii?
A: Taxiway radii vary by airport and aircraft type, but typically range from 30-150 meters for commercial airports.
Q3: How does aircraft weight affect turning speed?
A: While the basic formula provides a general calculation, actual turning speeds may need adjustment based on aircraft weight, center of gravity, and other operational factors.
Q4: Are there limitations to this calculation?
A: This calculation provides a theoretical value. Actual operational speeds should consider weather conditions, surface conditions, and specific aircraft performance characteristics.
Q5: Can this formula be used for all aircraft types?
A: The formula provides a general calculation suitable for most aircraft, but specific aircraft types may have unique performance requirements that should be considered.
