What is the total distance required for takeoff to clear a 50-foot obstacle at a pressure altitude of 4,000 ft with a calm headwind?

To determine the total distance required for takeoff to clear a 50-foot obstacle at a pressure altitude of 4,000 feet, you need to consider various factors such as aircraft performance charts, which provide the necessary data based on aircraft type and environmental conditions.

At a pressure altitude of 4,000 feet, the aircraft's engine performance might be slightly reduced compared to its performance at sea level because of thinner air. Additionally, the takeoff distance increases at higher altitudes due to factors like decreased engine power, changes in air density, and the reduced lift generated by the wings.

The presence of a calm headwind simplifies the calculation since it does not contribute any additional distance to the takeoff, allowing the aircraft to reach a safe speed more quickly.

Typically, performance charts specific to the aircraft will specify the distances required for takeoff at various weights, altitudes, and temperatures. For instance, the requirement to clear obstacles like a 50-foot height could be listed under the "takeoff distance to clear a 50-foot obstacle" section. Based on the conditions provided, the correct answer of 1,750 feet likely aligns with those performance charts, suggesting that at a pressure altitude of 4,000 feet and with a calm
