What does the term 'screen height' refer to during takeoff?

The term 'screen height' during takeoff refers specifically to the minimum height achieved over the runway before an engine failure occurs. This height is crucial because it indicates an aircraft's ability to safely climb away from the runway in case of an engine problem after takeoff. Knowing the screen height helps pilots ensure that the aircraft is at a safe elevation to either continue the takeoff or execute an emergency procedure, depending on the nature of the engine failure. This standard is especially important for ensuring safety in the event of an engine failure shortly after departure.
