At a temperature of 80°F and pressure altitude of 5,000 ft with a weight of 3,300 lb, what is the total takeoff distance over a 50-foot obstacle?

To determine the total takeoff distance over a 50-foot obstacle, several factors must be considered, including temperature, pressure altitude, and the aircraft's weight. The correct answer of 1,950 feet is derived from comprehensive calculations involving these variables.

At a pressure altitude of 5,000 feet and a temperature of 80°F, the performance of the aircraft is negatively impacted compared to standard conditions. Higher temperatures reduce air density, which affects engine power, propeller efficiency, and lift generated by the wings. This, combined with the specified weight of 3,300 lb, creates a need for a longer takeoff roll to achieve the necessary speed for obstacle clearance.

Calculations commonly employ performance charts or formulas that integrate these conditions. Given the weight of the aircraft and the environmental factors, the calculated takeoff distance to clear a 50-foot obstacle results in a total of approximately 1,950 feet, taking into account the reduced lift and increased drag at both the altitude and temperature specified.

Each component in the equation directly influences the distance required; understanding how weight and environmental conditions interact with aircraft performance is essential for accurate takeoff distance estimation. Thus, this scenario showcases the importance of considering all relevant aerodynamic principles and performance metrics when assessing takeoff
