The Distance along Straight Taxiway Centerline is a measurement in airport engineering that determines the required clearance distance along the centerline of a straight taxiway section, taking into account aircraft dimensions and fillet geometry at taxiway intersections.
The calculator uses the formula:
Where:
Explanation: This formula calculates the total distance required along the taxiway centerline by adding the length of the fillet ends to the aircraft's datum length, ensuring adequate clearance for aircraft maneuvering.
Details: Accurate calculation of taxiway centerline distances is crucial for airport design, ensuring safe aircraft movement, preventing wingtip collisions, and maintaining proper clearance between aircraft and taxiway edges or other obstacles.
Tips: Enter the length of each wedge-shaped end of the fillet and the datum length of the aircraft in meters. Both values must be non-negative numbers. The calculator will compute the required distance along the straight taxiway centerline.
Q1: What is a fillet in taxiway design?
A: A fillet is a curved section added at taxiway intersections to provide additional clearance for aircraft maneuvering, particularly for the wingtips of turning aircraft.
Q2: How is datum length of aircraft determined?
A: Datum length is typically provided by aircraft manufacturers and represents a reference measurement used for various aircraft performance and clearance calculations.
Q3: Why is this distance calculation important?
A: Proper distance calculation ensures that aircraft can safely taxi without risk of collision with obstacles, other aircraft, or taxiway edges, particularly during turns.
Q4: Are there standards for these measurements?
A: Yes, organizations like ICAO and FAA provide standards and guidelines for taxiway design, including fillet dimensions and clearance requirements based on aircraft categories.
Q5: Can this formula be used for all aircraft types?
A: The formula provides a general calculation, but specific aircraft may have unique requirements. Always consult relevant aviation standards and aircraft specifications for critical applications.
