What is the screen height for a single-engine during approach?

In aviation, the screen height during an approach typically refers to the minimum altitude at which certain critical decisions regarding the landing configuration and descent rate should be made. For a single-engine aircraft, the standard screen height during the approach phase is set at 50 feet. This allows pilots sufficient altitude for final checks on the aircraft's configuration, speed, and alignment with the runway.

At this altitude, pilots are able to effectively evaluate the aircraft's performance and make any necessary adjustments to ensure a safe landing. Staying at the specified height allows for a clear view of the runway environment, which is critical for a successful touchdown. Adhering to this standard is particularly important in single-engine operations where engine-out scenarios can be more critical.

Choosing a different height, such as 35 feet or other values listed, would not provide the same level of safety and operational performance in this phase of flight, as it may not offer adequate decision-making time to respond to any abnormalities. Thus, 50 feet is recognized as the appropriate screen height for single-engine aircraft during the approach.
