What does the term "screen height" refer to in aviation?

The term "screen height" in aviation specifically refers to the minimum height that an aircraft must reach before it passes the end of the clearway during takeoff. This concept is crucial for ensuring that aircraft have adequate altitude to maneuver safely, particularly when considering obstacles in the environment, such as buildings or terrain near the airport.

When an aircraft takes off, it must achieve a certain height before reaching the end of the runway or clearway to ensure it can continue its climb safely without risking a collision. This height is part of the required performance standards for takeoff, particularly as it relates to ensuring safety margins during critical phases of flight. Thus, understanding screen height is essential for flight crews and those involved in airport operations to mitigate risks associated with takeoff performance.
