What is a displaced threshold?

A displaced threshold refers to a section of runway where landing is not permitted, but it can be used for takeoff. This typically occurs in situations where obstacles exist near the beginning of the runway, necessitating that the landing start further along the runway, while operational safety still allows takeoffs to occur from the full length of the runway.

Displaced thresholds are marked on the runway, indicating to pilots where they should begin their landing approach, ensuring they do not land before reaching the designated point. This requirement is vital for maintaining safety in aircraft operations, particularly in constrained airport environments. Being familiar with the implications of displaced thresholds helps pilots make safe and informed decisions during takeoff and landing procedures.
