Methods and systems for performing landing gear operations. In one embodiment, a method for retracting a landing gear is useable with an aircraft having a gear door that at least partially covers a gear well when the landing gear is extended. The method can include receiving a first signal during movement of the aircraft down a runway for takeoff. The first signal can correspond to at least a first aspect of motion of the aircraft, such as upward rotation of the aircraft for liftoff. The gear door can be opened in response to receiving the first signal. The method can further include receiving a second signal after the aircraft has lifted off of the runway. The second signal can correspond to a second aspect of motion of the aircraft, such as the aircraft achieving a positive rate of climb. In response to receiving the second signal, the landing gear can be retracted into the gear well.

A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to detecting liftoff of the aircraft from the runway; after automatically initiating movement of the landing sear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 2. The method of claim 1 wherein receiving a request to retract the landing gear includes receiving a request associated with a control input manually generated by a pilot of the aircraft. 3. The method of claim 1, further comprising automatically initiating closure of the landing gear door when the landing gear is at least approximately in the retracted position. 4. A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to detecting upward rotation of the aircraft; after automatically initiating movement of the landing sear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 5. The method of claim 4 wherein receiving a request to retract the landing gear includes receiving a request associated with a control input manually generated by a pilot of the aircraft. 6. The method of claim 4, further comprising automatically initiating closure of the landing gear door when the landing gear is at least approximately in the retracted position. 7. A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well; after automatically initiating movement of the landing gear door, receiving a request to retract the landing gear; in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well; after initiating movement of the landing gear from the extended position to the retracted position, automatically reducing the speed of the landing gear as it moves toward the retracted position; and while the speed of the landing gear is being reduced, automatically initiating movement of the landing gear door from the open position to the closed position. 8. The method of claim 7 wherein automatically initiating movement of the landing gear door includes automatically initiating movement of the landing gear door in response to receiving a signal that is automatically generated, wherein the signal corresponds to at least a first aspect of motion of the aircraft. 9. The method of claim 8 wherein receiving a signal includes receiving a signal that is automatically generated at least partially in response to the aircraft reaching a preselected speed. 10. The method of claim 7 wherein receiving a request to retract the landing gear includes receiving a request associated with a control input manually generated by a pilot of the aircraft. 11. A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to receiving a signal that is automatically generated at least partially in response to the aircraft reaching a preselected attitude; after automatically initiating movement of the landing gear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 12. The method of claim 11, further comprising automatically initiating closure of the landing gear door when the landing gear is at least approximately in the retracted position. 13. A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to receiving a signal that is automatically generated at least partially in response to the aircraft generating a preselected amount of lift; after automatically initiating movement of the landing gear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 14. The method of claim 13, further comprising automatically initiating closure of the landing gear door when the landing gear is at least approximately in the retracted position. 15. A method for retracting a landing gear of an aircraft, the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to receiving a signal that is automatically generated at least partially in response to a change in load on the landing gear; after automatically initiating movement of the landing gear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing sear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 16. The method of claim 15, further comprising: after initiating movement of the landing gear from the extended position to the retracted position, automatically reducing the speed of the landing gear as it moves toward the retracted position; and while the speed of the landing gear is being reduced, automatically initiating movement of the landing gear door from the open position to the closed position. 17. A method for retracting a landing gear of an aircraft, wherein the aircraft includes a fuselage and a nose gear extendable downwardly from the fuselage, and the method comprising: after the aircraft has lifted off a runway, automatically initiating movement of a landing gear door to an open position from a closed position in which the landing gear door at least partially covers a landing gear well, in response to receiving a signal that is automatically generated in response to a change in load on the nose gear; after automatically initiating movement of the landing gear door, receiving a request to retract the landing gear; and in response to receiving the request to retract the landing gear, initiating movement of the landing gear from an extended position to a retracted position in which the landing gear is at least partially positioned in the landing gear well. 18.
