Abstract
An up-lock apparatus for landing gear of an aircraft includes a hook member configured to receive an up-lock roller pin of the landing gear when the landing gear is retracted. An up-lock actuator is coupled to the hook member and is configured to maintain the hook member in a locked state responsive to a first movement of the up-lock roller pin against the hook member to thereby prevent deployment of the landing gear. The up-lock actuator is further configured to allow the hook member to move to a released state responsive to a second movement of the up-lock roller pin against the hook member to facilitate deployment of the landing gear.
