To determine the required ground roll for takeoff over a 50-foot obstacle at a temperature of 80 degrees Fahrenheit and a pressure altitude of 2,000 feet with a weight of 3,300 pounds, it’s critical to consider how these factors influence aircraft performance.

At a temperature of 80 degrees Fahrenheit and a pressure altitude of 2,000 feet, the aircraft will experience a decrease in engine power and propeller efficiency compared to standard conditions. The reduced air density at higher altitudes and temperatures affects the lift generated by the wings as well as the thrust produced by the engines. This combination leads to a longer takeoff distance, especially when clearing obstacles.

Calculating the specific ground roll typically involves using performance charts or calculations provided in the Pilot's Operating Handbook (POH) for the aircraft type. These calculations incorporate the aircraft's weight and the environmental conditions affecting its performance.

In this scenario, given that the required takeoff ground roll needs to clear a 50-foot obstacle, it is expected that a significant takeoff distance will be necessary. The choice of 1,950 feet indicates acknowledgment of the factors affecting performance in non-standard conditions (such as temperature and altitude) along with the weight of the aircraft. This distance accounts for
