Starting at zero, you used 1,334 feet to achieve liftoff velocity. After liftoff you displaced an additional distance of 185 feet (total distance 1,519 feet) to acquire 54 feet AGL. This represents an average 360 ft/min climb rate. All takeoff climb charts reflect a straight out departure. Any turn to avoid terrain, trees, obstacles would alter the horizontal lift component; and degrade the climb gradient even more! Knowledgeable and experienced high density altitude flight instructors and pilots are valuable resources. Their insights and suggestions can populate the areas under these curves. A graph is a system integration model representing airplane, environment, and human operator (the pilot).
