Stopway Clearway Credit
A precise tool.
What is the Stopway Clearway Credit & How does it work?
Stopway and clearway are essential components of airport runways, designed to enhance safety during takeoff and landing operations. Stopway is the area beyond the runway end that can be used for rejected takeoffs, while clearway extends further from the runway end to provide additional clearance for obstacles.
The stopway credit allows an aircraft to use a portion of the stopway as if it were part of the runway itself, thereby increasing the effective length available for takeoff. Similarly, clearway credit provides a margin of safety by allowing the aircraft to operate with reduced climb gradients.

Frequently Asked Questions
What is stopway credit in aviation?
Stopway credit allows an aircraft to use a portion of the stopway as if it were part of the runway, increasing the effective length available for takeoff.
How does clearway differ from stopway?
Clearway extends further from the runway end than stopway and provides additional clearance for obstacles, while stopway is used for rejected takeoffs.
Why are stopway and clearway important in aviation?
Stopway and clearway enhance safety by providing extra space for rejected takeoffs and obstacle clearance during takeoff and landing operations.
Can I use the entire stopway as part of my runway length?
No, only a portion of the stopway can be used as stopway credit, depending on specific regulations and aircraft requirements.
How do I calculate the stopway credit for my aircraft?
To calculate stopway credit, you need to consider factors such as aircraft weight, runway conditions, and regulatory requirements. Consult your aircraft’s manual or aviation authorities for precise calculations.
What are the benefits of having a clearway on an airport runway?
A clearway provides additional space beyond the runway end to ensure safe passage over obstacles, reducing the risk of accidents during takeoff and landing.
Are stopway and clearway requirements different for every aircraft type?
Yes, stopway and clearway requirements can vary based on the aircraft type, weight, and specific operational needs. Always refer to your aircraft’s manual and local aviation regulations for accurate requirements.
