What is the maximum runway slope allowed for the ERJ 170/175?

The maximum allowed runway slope for the ERJ 170/175 is indeed +/- 2.0%. This limitation is in place to ensure safe takeoff and landing operations. Runway slope can significantly impact aircraft performance during these critical phases of flight. A slope greater than this specified limit could affect the aircraft's braking effectiveness, accelerate the potential for runway excursions, and hinder the overall control of the aircraft, especially during adverse weather conditions or emergency situations.

Having a maximum slope limitation helps flight crews to evaluate the suitability of a runway before takeoff or landing, ensuring that they adhere to safe operational practices in various airports around the world. For the ERJ 170/175 specifically, this means any runway with slopes exceeding +/- 2.0% should be avoided to maintain safe operational margins.
