Stopway Distance Formula:
| From: | To: |
Stopway Distance is defined as a rectangular area on the ground at the end of take-off run available prepared as a suitable area in which an aircraft can be stopped in the case of an interrupted take-off.
The calculator uses the Stopway Distance formula:
Where:
Explanation: The stopway distance is calculated by subtracting the full strength pavement distance from the total field length available for aircraft operations.
Details: Accurate stopway distance calculation is crucial for airport design, aircraft performance calculations, and ensuring safety during take-off and landing operations. It provides a safety margin for aircraft that need to abort take-off.
Tips: Enter field length and full strength pavement distance in meters. Both values must be positive numbers, and field length should be greater than or equal to full strength pavement distance.
Q1: What is the purpose of a stopway?
A: A stopway provides an area beyond the runway where an aircraft can be safely stopped in case of an aborted take-off, enhancing operational safety.
Q2: How does stopway differ from runway?
A: While a runway is designed for normal take-off and landing operations, a stopway is specifically prepared for stopping aircraft during emergency situations and may not have the same structural strength as the main runway.
Q3: When is stopway distance most critical?
A: Stopway distance is most critical during take-off performance calculations, especially for aircraft operating at or near their maximum take-off weight limits.
Q4: Are there regulatory requirements for stopway design?
A: Yes, aviation authorities like ICAO and FAA have specific regulations and standards for stopway design, dimensions, and surface characteristics.
Q5: Can stopway be used for normal operations?
A: Generally, stopways are not intended for normal aircraft operations and are reserved for emergency use only to ensure they remain available when needed.
