AVIATION & AERONAUTIC CALCULATOR
Glide Range
A precise tool.
What is the Glide Range & How does it work?
The glide range of an aircraft is the horizontal distance it can travel in the air without any engine power, relying solely on its momentum and lift-to-drag ratio (L/D). This is a critical factor for understanding the aircraft’s performance during emergencies or when gliding to a safe landing.
The glide range can be calculated using the formula:
text{Glide Range} = frac{V_{infty}^2}{g} times frac{L}{D}
V_infty = speed at infinity, g = acceleration due to gravity, L/D = lift-to-drag ratio
This formula shows that the glide range is directly proportional to the square of the aircraft’s airspeed and its lift-to-drag ratio.

Frequently Asked Questions
What is glide range in aviation?
Glide range is the horizontal distance an aircraft can travel without engine power, relying on momentum and lift-to-drag ratio.
How do I calculate glide range?
Use the formula: Glide Range = (V∞^2 / g) × (L/D), where V∞ is speed at infinity, g is gravity, and L/D is lift-to-drag ratio.
Why is glide range important in aviation?
Glide range is crucial for understanding aircraft performance during emergencies or when gliding to a safe landing.
What factors affect an aircraft’s glide range?
An aircraft’s glide range is affected by speed at infinity, gravity, and the lift-to-drag ratio of the aircraft.
Can I use this calculator for any type of aircraft?
Yes, you can use this calculator for any type of aircraft as long as you have the necessary parameters: speed at infinity, gravity, and lift-to-drag ratio.
What does L/D stand for in glide range calculations?
L/D stands for lift-to-drag ratio, which is a measure of an aircraft’s efficiency in producing lift with minimal drag.
How do I determine the speed at infinity (V∞) for my aircraft?
Speed at infinity (V∞) can be determined by considering the aircraft’s stall speed and other aerodynamic factors specific to its design.
