1. What is Stopway Distance?

Stopway Distance is defined as a rectangular area on the ground at the end of take-off runway specifically designed to accommodate aircraft in case of aborted take-off or other emergencies.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( SW \) — Stopway Distance (m)
• \( DAS \) — Distance to Accelerate and Stop (m)
• \( FS \) — Full Strength Pavement Distance (m)

Explanation: The formula calculates the additional distance required beyond the full strength pavement to safely stop an aircraft during aborted take-off scenarios.

3. Importance of Stopway Distance Calculation

Details: Accurate stopway distance calculation is crucial for airport runway design, ensuring aircraft safety during emergency situations, and complying with aviation safety regulations.

4. Using the Calculator

Tips: Enter Distance to Accelerate and Stop and Full Strength Pavement Distance in meters. Both values must be positive numbers, and DAS should be greater than or equal to FS.

5. Frequently Asked Questions (FAQ)

Q1: What is the purpose of a stopway?
A: A stopway provides additional safety area for aircraft to safely stop in case of aborted take-off or other emergency situations.

Q2: How is stopway different from runway?
A: While runways are designed for normal take-off and landing operations, stopways are specifically designed for emergency stopping and may not have the same structural strength as the main runway.

Q3: What factors affect stopway distance requirements?
A: Aircraft type, weight, speed, runway conditions, and environmental factors all influence stopway distance requirements.

Q4: Are there international standards for stopway design?
A: Yes, organizations like ICAO and FAA provide detailed guidelines and standards for stopway design and dimensions.

Q5: Can stopway be used for normal operations?
A: Typically, stopways are not used for normal take-off or landing operations as they may not have the same structural strength as the main runway.
