What is the calculated takeoff distance at a temperature of 60 degrees Fahrenheit?

The calculated takeoff distance at a temperature of 60 degrees Fahrenheit reflects how temperature affects aircraft performance, particularly during takeoff. Typically, warmer temperatures can increase takeoff distance due to reduced air density, which decreases engine performance and lift generated by the wings.

At 60 degrees Fahrenheit, the air is relatively dense compared to warmer temperatures, which allows for optimal engine performance and lift. Therefore, the takeoff distance is not excessive and would likely be around the mid-range of the provided options.

The choice of 660 feet as the calculated takeoff distance indicates a consideration of several factors, such as aircraft weight, elevation of the airport, and standard performance charts provided in the pilot operating handbook or performance manuals. These charts are used to determine accurate takeoff distances under various environmental conditions. In this scenario, 660 feet appropriately balances these factors, making it a reasonable estimate for the takeoff distance at this temperature, as opposed to the other options that would either underestimate or overestimate the impact of conditions on performance.
