How high should you be at the departure end of the runway on takeoff?

The proper altitude at the departure end of the runway (DER) is crucial for ensuring a safe takeoff. An altitude of at least 35 feet above the DER elevation is established as a safety standard. This height provides sufficient clearance for obstacles that may be located near the departure end of the runway, such as fences, buildings, or terrain features. Maintaining this altitude helps to ensure that pilots have adequate vertical separation from potential hazards, allowing for a controlled climb rate in the initial phase of flight.

Achieving and exceeding this minimum altitude also allows pilots to comfortably account for any variations in climb performance due to factors like aircraft weight, environmental conditions, and engine performance. While other altitude options might also seem valid, 35 feet is specifically recommended as a baseline to ensure safety during takeoff, taking into account standard operating procedures and guidelines.
