What is the maximum ambient temperature allowed for takeoff and landing in the ERJ 170/175?

The maximum ambient temperature allowed for takeoff and landing in the ERJ 170/175 is 52 degrees Celsius. This limitation is critical as it ensures safe operations of the aircraft under high-temperature conditions. Exceeding this temperature can affect the aircraft's performance characteristics, including climb rates, engine efficiency, and overall handling qualities.

Operating within this temperature limit is essential as high ambient temperatures can lead to reduced engine thrust and may require longer takeoff distances due to decreased air density. Pilots must always be aware of these limitations to ensure that aircraft performance is within safe operational parameters. By adhering to this maximum temperature, pilots help ensure a safer and more efficient flight operation, particularly in hot weather conditions.
