Strip Width Formula:
Definition: This calculator determines the required strip width for a runway based on the separation distance from a parallel taxiway and the aircraft wingspan.
Purpose: It helps airport engineers and planners design safe runway areas that accommodate aircraft operations and potential excursions.
The calculator uses the formula:
Where:
Explanation: The separation distance is divided by 0.5 (a standard factor) and then the wingspan is subtracted to determine the appropriate strip width.
Details: Proper strip width ensures safety margins for aircraft operations, reduces damage risk during excursions, and meets aviation regulations.
Tips: Enter the separation distance and wingspan in meters. The ±5% indicates the acceptable tolerance range for these measurements.
Q1: Why is the separation distance divided by 0.5?
A: The 0.5 factor is a standard ratio used in airport design to ensure adequate safety margins between parallel runways and taxiways.
Q2: What does the ±5% tolerance mean?
A: This indicates that the actual values may vary up to 5% from the entered values while still producing valid results.
Q3: How do I determine the separation distance?
A: Separation distance is typically determined by aircraft size, airport category, and regulatory requirements (e.g., ICAO or FAA standards).
Q4: What wingspan should I use for calculations?
A: Use the wingspan of the largest aircraft expected to regularly use the runway.
Q5: Does this calculation account for all safety factors?
A: This provides a baseline calculation. Actual designs should consider additional safety factors and local regulations.
