Obstacle height is generally referenced to the elevation at the end of the take-off distance. Assuming the climb gradient is constant, the flight path of an slope runway will begin at a relatively Elevation.
Understand the Problem
The question is asking to complete a statement about obstacle height and flight path in relation to runway slopes and elevation, focusing on the relationship between the take-off distance and the climb gradient.
Answer
The flight path begins at a lower/higher elevation at TODR's end, varying by slope.
The flight path of a sloped runway begins at a relatively lower or higher elevation depending on the slope's direction (uphill or downhill) at the end of the take-off distance.
Answer for screen readers
The flight path of a sloped runway begins at a relatively lower or higher elevation depending on the slope's direction (uphill or downhill) at the end of the take-off distance.
More Information
The answer is derived from understanding that the elevation at the end of the take-off distance (TODR) is critical for starting the flight path, especially on a sloped runway.
Tips
One common mistake is not considering the slope's direction, which affects the elevation start point.
