📖
What is the Landing Load Factor & How does it work?

The landing load factor is a critical parameter in aviation that indicates the ratio of the lift force to the weight of an aircraft during landing. This factor is influenced by various parameters, including the sink rate and spring-back characteristics of the aircraft.

Sink rate refers to the vertical speed at which the aircraft descends during landing. A higher sink rate increases the load factor because the aircraft must generate more lift to slow down its descent.

Spring-back is the tendency of an aircraft to bounce or oscillate after touchdown due to the elasticity of the landing gear and other structural components. This can also contribute to higher load factors during landing.

n_z = frac{2V_s}{Delta h}
n_z = Load factor, V_s = Sink rate, Delta h = Spring-back height

Frequently Asked Questions
What is the landing load factor in aviation?
The landing load factor is the ratio of lift force to weight during landing, influenced by sink rate and spring-back.
How does a higher sink rate affect the landing load factor?
A higher sink rate increases the landing load factor because more lift is needed to decelerate the aircraft vertically.
What is spring-back in aviation terms?
Spring-back refers to an aircraft’s tendency to rebound after touchdown, affecting how much force is exerted on the landing gear.
Why is the landing load factor important for pilots?
It helps pilots understand the structural stresses on the aircraft during landing, ensuring safe operations.
How can I reduce the landing load factor?
Reducing sink rate and optimizing approach speed can help decrease the landing load factor.
What factors besides sink rate affect the landing load factor?
The weight of the aircraft, configuration (flaps, slats), and surface conditions also influence the landing load factor.
Can you explain how to use this calculator for a specific aircraft?
Input the aircraft’s sink rate and spring-back characteristics into the calculator to determine the landing load factor.
