An airstair system with a deployable upper step. Airstair systems and associated methods are disclosed. In one embodiment, the airstair comprises a deployable upper step, a primary deployment device and a secondary deployment device. The upper step is movable between a stowed configuration when a door of the aircraft is closed and a deployed configuration when the door is open. The primary deployment device resiliently biases the upper step toward the deployed configuration. The secondary deployment device is movable in coordination with a movement of the door and configured to drive the deployable upper step toward the deployed configuration during opening of the door and during a failure of the primary deployment device.
具有可展开的上部台阶的登机梯系统。公开了登机梯系统和相关方法。在一个实施例中,登机梯包括可展开的上部台阶、主展开装置和副展开装置。上部台阶能够在当飞机的门关闭时的收起构造和当门打开时的展开构造之间移动。主展开装置朝向展开构造弹性偏置上部台阶。副展开装置能够与门的运动协调地移动,并且构造成用以在门的打开期间且在主展开装置的故障期间朝向展开构造驱动可展开的上部台阶。
