What is the maximum allowable temperature for takeoff and landing?

The correct answer indicates that the maximum allowable temperature for takeoff and landing is ISA +35°C. This limitation is crucial because it defines the operational envelope for safety and performance of the aircraft. At temperatures exceeding these limits, the aircraft may experience performance degradation, including reduced engine thrust, longer takeoff distances, and potential challenges with climb rates.

The International Standard Atmosphere (ISA) is a model of the atmosphere used for standardizing environmental conditions, and deviations from these standards can significantly affect aircraft performance. By utilizing ISA +35°C as the upper limit, operators ensure they are within a safer, more manageable range for takeoff and landing operations.

Ensuring compliance with this temperature threshold not only adheres to regulatory limitations but also enhances safety by maintaining optimal operational performance of the CRJ 200.
