Airport Overview
Runway Features and Markings
- Assume the aircraft will taxi onto the runway and turn left to move into the takeoff position (Figure 2).
Displaced Threshold
- A displaced landing threshold is located some distance from the beginning of the runway surface. The displaced threshold is used to move an aircraft’s final approach or glide path down the runway so that aircraft will maintain a higher altitude approaching the runway, either for noise reduction or obstacle clearance.
Conclusion
- Runway markings are consistent from one airport to another, especially airports that are certified for commercial aircraft traffic. The markings for different runway features have been standardized for many years. Once familiar with these standardized marking a pilot will have no difficulty understanding when and where to stop and hold position, and how to plan takeoffs an…
