What is the maximum altitude for taking off with a tailwind in the ERJ 175?

The maximum altitude for taking off with a tailwind in the ERJ 175 is indeed FL100, or 10,000 feet. This limitation is in place to ensure the safe and optimal performance of the aircraft during takeoff, especially in conditions where a tailwind could affect the aircraft's initial climb performance.

At altitudes above 10,000 feet, the aircraft may encounter changes in air density and performance characteristics that could result in undue stress on the engines and airframe, compromising safety. The limitation is set as a precaution to maintain safe operational practices, assisting pilots in making informed decisions based on performance data. This ensures that the aircraft adheres to safety standards and performance criteria established for safe flight operations.
