1. A landing gear actuation system, comprising:
a side stay, wherein the side stay, when extended, is configured support for movable member to stay extended;
a wheel assembly;
a locking link, wherein a first end of the locking link is coupled to the side stay and an intermediate portion of the locking link is coupled to the movable member and wherein the locking link is configured to provide locking support to the side stay to keep the side stay extended;
an attachment point integral to a movable member between the side stay and the wheel assembly of the movable member;
a flexible pull member having a first end coupled to the attachment point;
a motor configured to engage the flexible pull member and to:
responsive to receiving a command to retract the movable member, exert a force to pull the flexible pull member to retract the movable member; and
responsive to receiving a command to extend the movable member, exert a force to advance the flexible pull member in a controlled manner to extend the movable member, wherein the movement of the flexible pull member moves the attachment point and the movable member; and
a first dampener, wherein a first end of the first dampener is coupled to a second end of the locking link and a second end of the first dampener is coupled to the side stay, the first dampener configured to, when extended, provide support to the side stay in the extended position and configured to, when extending, provide controlled descent of the movable member.
