Which instability arises, causing reduced braking, when accumulator pre-charge drops below a minimum threshold value in an Aircraft hydraulic braking system?

💡 Explanation

Pressure Modulation Failure results because Nitrogen pre-charge degradation prevents proper damping by the accumulator. This lost damping causes hydraulic pressure oscillations, resulting in uneven braking, therefore causing modulation failure, rather than component degradation that would have longer time constants.
