Glide Distance Calculator

How to Use This Calculator

1. Enter your current altitude in feet (actual flight altitude)
2. Enter your current airspeed in knots (indicated airspeed)
3. Enter the wind speed in knots (use negative value for headwind)
4. Enter your desired approach angle in degrees (typically between 10-30 degrees)
5. Click the Calculate button to compute the glide distance and time

Understanding Glide Distance

Glide distance is the horizontal distance an aircraft can travel forward while descending without engine power. It's calculated based on the aircraft's altitude, airspeed, wind conditions, and approach angle.

The formula used in this calculator is:

Glide Distance = (Altitude × 3.46) / (Airspeed + Wind Speed × cos(Approach Angle))

Important Notes

• This calculator provides theoretical glide distance and should be used as a planning tool only
• Actual glide performance may vary based on aircraft type, configuration, and other factors
• In emergency situations, always prioritize actual terrain assessment and available landing options
• The calculator does not account for factors like wind shear, temperature changes, or aircraft weight variations

Practical Applications

Pilots can use this calculator to:

• Evaluate emergency landing options during engine failure
• Plan for fuel reserves and emergency procedures
• Understand how different wind conditions affect landing distance
• Practice emergency descent scenarios during training
