What is the estimated takeoff distance at a temperature of 50 degrees Fahrenheit?

To determine the estimated takeoff distance at a temperature of 50 degrees Fahrenheit, it is important to consider the effects of temperature on aircraft performance. As temperature increases, air density decreases, which can hinder an aircraft's performance, particularly during takeoff.

At 50 degrees Fahrenheit, the performance charts for the specific aircraft in question would indicate a takeoff distance required under standard conditions at that temperature. In this case, the choice of 636 feet is derived from the aircraft’s performance data, which typically includes variables such as weight, altitude, wind, and temperature. At 50 degrees, the takeoff distance would be lower than higher temperatures, showcasing that the aircraft can perform relatively efficiently at this temperature due to the more favorable air density than at warmer temperatures.

The other options present different distances that may not accurately reflect the true performance data for an aircraft under the given conditions. The 636 feet figure aligns with typical performance expectations for aircraft at moderate temperatures, assuming standard pressure and other conditions are met.

Understanding these performance parameters is crucial for pilots during flight planning to ensure safe takeoff distances are achievable based on current atmospheric conditions.
