An aircraft includes a brake lever for receiving a pilot braking input as a lever travel of the brake lever, a braking wheel operatively coupled with the brake lever to brake the aircraft based on the lever travel, a brake actuator operatively coupled with the braking wheel to apply a braking force in response to a braking pressure provided to the brake actuator, and a brake pressure circuit. The brake pressure circuit is configured for: estimating a maximum braking pressure above which the braking wheel will skid with respect to a ground surface; scaling a lever gain of the brake lever to command the maximum braking pressure at a full travel of the brake lever such that a remaining brake lever travel indicates the amount of braking capability remaining for the aircraft; and braking the braking wheel based on the lever gain and the lever travel.
一种飞机,包括:制动杆,用于接收驾驶员制动输入作为制动杆的杆行程;制动轮,与制动杆可操作地联接,以基于杆行程对飞机进行制动;制动致动器,与制动轮可操作地联接,以响应于提供给制动致动器的制动压力来施加制动力;以及制动压力回路。制动压力回路被配置用于:估计最大制动压力,高于该最大制动压力,制动轮将相对于地面表面打滑;缩放制动杆的杆增益以在制动杆的全行程处命令最大制动压力,使得剩余制动杆行程指示飞机剩余的制动能力量;以及基于杆增益和杆行程对制动轮进行制动。
