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

• A. 1,400 feet
• B. 1,724 feet
• C. 2,023 feet
• D. 1,850 feet

Answer: (B)

To determine the approximate total distance required to clear a 50-foot obstacle at a temperature of 20°C and a pressure altitude of 1,000 ft, one must consider a few factors related to aircraft performance, including the aircraft's takeoff distance and climb performance.

At a temperature of 20°C and a pressure altitude of 1,000 ft, the performance of the aircraft will be fairly standard, enabling pilots to utilize established charts and performance data. In typical conditions, the required distance to clear a 50-foot obstacle can be computed using performance data from the aircraft's flight manual, which provide the necessary calculations for various altitudes and temperatures.

The correct answer indicates that the total distance required to clear the obstacle is approximately 1,724 feet. This figure reflects the combined distances of the takeoff run and the initial climb. It accounts for the need for additional distance to ensure that the aircraft can gain sufficient altitude safely above the obstacle while considering the aircraft's performance capabilities at the specific temperature and altitude.

Consistently, pilots rely on these performance calculations to ensure safety and compliance with regulatory standards, taking into consideration that most scenarios including a 50-foot obstacle will require detailed knowledge of the aircraft's capabilities along with specific environmental conditions.
