What is the minimum brake/APU accumulator pressure required for riding brake?

The minimum brake/APU accumulator pressure required for riding brake is generally established at 2900-3000 psi. This pressure range is critical because it ensures that the hydraulic system has sufficient force to effectively engage the brakes. Riding brake pressure is necessary for safe and controlled movement of the aircraft, particularly during taxiing, takeoff, and landing operations.

Maintaining proper accumulator pressure is vital; lower pressures can compromise braking performance, potentially leading to hazardous situations. Therefore, the specification for 2900-3000 psi is designed to provide an adequate safety margin, ensuring the braking system is fully operational under various conditions. Understanding these safety parameters is essential for anyone involved in aircraft maintenance or operations.
