For a landing at 3,750 ft pressure altitude with a headwind of 12 kts, what is the total distance required to land over a 50-foot obstacle?

To determine the total distance required for landing over a 50-foot obstacle at a pressure altitude of 3,750 feet with a headwind of 12 knots, it's essential to consider how both altitude and wind conditions affect landing distance.

At higher altitudes, the air is less dense, which can lead to increased landing distances due to reduced aerodynamic performance. The presence of a headwind is beneficial because it reduces the groundspeed at which the aircraft approaches the runway, allowing for a shorter distance required to land.

Generally, when calculating landing distance over an obstacle, you would factor in the aircraft's landing distance in still air, then adjust for altitude and the wind conditions. Using performance charts specific to the aircraft type should reveal that the landing distance is reduced under a headwind, making the landing shorter than it would be in still air or with a tailwind.

In this scenario, the calculations would take into account the normalized landing distance for your altitude, the effect of the aircraft weight, and finally, the mitigating factor of the headwind. After applying the necessary adjustments and calculations, the total distance required to land over a 50-foot obstacle leads to the conclusion that 816 feet is the correct figure based on these variables.

Thus, understanding how
