Answer :
Final answer:
When approaching a runway with steeply sloping terrain leading down to it, you sense you are higher than the terrain and will fly a shallower approach to adjust for the visual illusion and ensure a safe landing.
Explanation:
When approaching a runway with steeply sloping terrain leading down to it, as a pilot, you may sense that you are higher than the terrain and will therefore fly a shallower approach. The reason behind this perception is due to the visual illusion that the sloping terrain can cause, making it seem like the aircraft is at a higher altitude relative to the runway than it actually is. Pilots must anticipate this effect and adjust their approach path accordingly to ensure a safe descent and landing on the level runway.
Slope is defined as the ratio of the rise to the run. In aviation, understanding and interpreting the slope of the terrain is crucial for pilots during takeoff and landing phases. If the approach slope is not adjusted for a downhill slope, the aircraft might land beyond the desired touchdown point on the runway, which can be dangerous. Conversely, a steep incline leading up to the runway could result in an approach that is too steep, causing safety issues as well.
