What is the maximum ambient temperature for takeoff and landing?

The maximum ambient temperature for takeoff and landing for the ERJ 170/175 is indeed +50°C. This limitation is crucial because it defines the operational envelope of the aircraft concerning ambient temperature, ensuring that performance parameters remain within safe and effective limits. Operating at temperatures above this threshold can affect engine performance, climb rates, and overall safety margins, as higher temperatures reduce air density and engine efficiency.

The established limitation of +50°C helps to mitigate risks associated with engine operation and aerodynamic performance during critical phases of flight such as takeoff and landing, where performance is vital for safety. Keeping within this temperature limit allows for optimal engine operation and aircraft handling characteristics.
