What does LDA stand for in aviation?

LDA stands for Landing Distance Available in aviation, which refers to the length of runway that is available for an aircraft to land safely. This distance is a crucial consideration for pilots because it directly impacts their landing approach and technique. Knowing the LDA helps ensure that the aircraft can slow down and stop within the designated runway length, taking into account factors such as aircraft weight, weather conditions, and runway gradient.

Understanding Landing Distance Available is vital for compliance with safety regulations and effective operational planning, especially in Part 135 operations where precise performance calculations are essential for passenger safety and efficiency. The concept of LDA helps pilots make informed decisions about approach angles, speed, and landing techniques, ensuring they have adequate distance to stop safely after touchdown.
