The maximum ambient temperature for takeoff and landing is critical to ensuring safe aircraft performance. The International Standard Atmosphere (ISA) serves as a baseline for various aviation calculations, including performance metrics.

When answering this question, the correct choice indicates that the maximum ambient temperature is ISA +35°C. This limit ensures that the aircraft can safely perform takeoff and landing maneuvers while maintaining optimal performance characteristics. Exceeding this temperature can lead to decreased engine performance, reduced climb rates, and heightened risk during critical phases of flight, particularly in high-density altitudes.

Choosing a value higher than ISA +35°C would compromise vehicle performance due to the increased density altitude, which directly affects lift generation and engine thrust, leading to potential challenges during takeoff and landing phases. Therefore, adhering to the ISA +35°C parameter provides a significant safety margin for operators.
