What is the maximum allowable slope for a runway in CRJ Operations?

The maximum allowable slope for a runway in CRJ operations is ±2%. This limitation is critical because it ensures safe takeoff and landing conditions for the aircraft. A slope exceeding this limit can significantly affect aircraft performance, particularly during the approach and landing phases or when taking off, where engine thrust and lift are critically impacted by the runway's angle.

Runways with a slope greater than ±2% could lead to challenges in maintaining control of the aircraft, reduced braking effectiveness, and potential difficulties during taxi operations. Pilots are trained to be aware of these limitations to ensure that they operate the aircraft within safe parameters, and not adhering to these guidelines might lead to operational hazards. In summary, the ±2% figure represents a balance between functional capabilities of the aircraft and operational safety standards in aviation.
