1. An aircraft landing gear system, comprising:
a landing gear;
a landing gear retraction system configured to retract the landing gear;
a landing gear bay door;
a landing gear bay door actuator configured to move the landing gear bay door between a closed position and an open position relative to a door frame;
a landing gear controller configured, during an aircraft take-off procedure, to cause the landing gear retraction system to perform only a first portion of a landing gear retraction process, wherein the landing gear controller responds to a status of the aircraft to cause the performance of the first portion and cause the performance of the first portion before receiving a command to retract the landing gear,
wherein the first portion of the landing gear retraction process includes the landing gear retraction system actuating the landing gear bay door actuator to positively hold the landing gear bay door in the closed position until at least the command is received.
