The landing distance of an aircraft is the distance it requires to decelerate, descend, and touch down safely on a runway or landing surface during a landing maneuver. It is an essential parameter in aircraft design and operation, as it determines the runway length needed for a safe landing.
The formula for calculating landing distance () is similar to the takeoff distance formula and involves several factors. Here’s a simplified version of the formula:
- is the landing distance (in meters or feet).
- is the landing speed (in meters per second or feet per second).
- is the gravitational acceleration (approximately 9.81 m/s² or 32.2 ft/s²).
- is the lift-to-weight ratio (dimensionless).
- is the coefficient of friction of the runway (dimensionless).
