What is the approximate total distance required to clear a 50-foot obstacle at a pressure altitude of 1,000 ft and temperature of 20 °C?

To determine the total distance required to clear a 50-foot obstacle at a pressure altitude of 1,000 feet and a temperature of 20 °C, it is essential to understand how pressure altitude and temperature affect aircraft performance characteristics, especially during the climb phase.

The required distance to clear an obstacle can significantly depend on factors such as the aircraft’s weight, configuration, and prevailing atmospheric conditions. At a pressure altitude of 1,000 feet, the air density is relatively close to standard, and a temperature of 20 °C does not deviate significantly from standard temperature conditions.

Using standard climb performance charts or calculations, we can evaluate the expected ground roll and climb distance needed to clear a 50-foot obstacle. The obstacle clearance distance is usually derived from specific performance parameters that include initial climb rate and the required climb gradient.

For the given parameters, a distance of approximately 1,724 feet aligns well with the calculations made using standard performance charts which factor in the aircraft's climb performance at those specified altitudes and temperatures. This figure accounts for a combination of the initial climb distance necessary to reach the 50-foot obstacle clearance while also factoring in safe margin requirements during climb operations.

By evaluating the performance characteristics under these specific conditions, it's clear
