What does LDA represent in aviation terminology?

LDA, or Landing Distance Available, refers to the length of runway declared suitable for aircraft landing. This measure is crucial in aviation operations as it indicates the distance along the runway that is available for an aircraft to come to a complete stop after landing. This factor is particularly important for pilots to assess whether an aircraft can safely land on a runway given its weight, weather conditions, and other variables affecting landing performance.

The determination of LDA takes into account any obstacles beyond the runway threshold that may limit landing distance. Therefore, it is a critical component for flight planning and safety assessments, ensuring that pilots are making informed decisions about their landing strategies. Understanding the LDA helps pilots choose the appropriate airports for landing and ensures compliance with safety regulations related to runway operations.
