1. What Is Clearway Distance For Continued Takeoff?

Clearway Distance is the difference between takeoff distance available (TODA) and takeoff run available (TORA). It represents the area beyond the runway that is free of obstacles and can be used for aircraft takeoff procedures.

2. How Does The Calculator Work?

The calculator uses the Clearway Distance formula:

Where:

• \( CL \) — Clearway Distance (m)
• \( D35 \) — Distance to Clear 35 ft Obstacle (m)
• \( sLO \) — Liftoff Distance (m)

Explanation: The formula calculates the required clearway distance based on the difference between the distance needed to clear a 35-foot obstacle and the actual liftoff distance, with a 50% safety factor.

3. Importance Of Clearway Distance Calculation

Details: Accurate clearway distance calculation is crucial for aircraft safety during takeoff operations, ensuring there is adequate obstacle-free area beyond the runway for aircraft to safely become airborne and clear obstacles.

4. Using The Calculator

Tips: Enter Distance to Clear 35 ft Obstacle and Liftoff Distance in meters. Both values must be positive, and the obstacle distance must be greater than the liftoff distance.

5. Frequently Asked Questions (FAQ)

Q1: Why is clearway distance important for aircraft operations?
A: Clearway distance provides additional safety margin beyond the runway, allowing aircraft to safely clear obstacles during takeoff, especially in emergency situations or when performance is marginal.

Q2: What factors affect clearway distance requirements?
A: Aircraft type, weight, runway conditions, temperature, altitude, and obstacle height all influence clearway distance requirements.

Q3: How is clearway distance different from stopway?
A: Clearway is an area beyond the runway for aircraft to become airborne, while stopway is an area for aircraft to stop during aborted takeoffs.

Q4: Are there regulatory standards for clearway distance?
A: Yes, aviation authorities like FAA and EASA have specific regulations governing clearway distance requirements based on aircraft performance categories.

Q5: When is clearway distance most critical?
A: Clearway distance is particularly important for airports with obstacles near the departure end of runways, during hot/high altitude operations, and for aircraft operating near their maximum takeoff weight.
