Integrated hoist maintenance and method of hoist operation

1. A method comprising:

operating a hoist assembly in an operating mode, wherein the hoist assembly deploys and retrieves a cable from a cable drum rotatable about a cable drum axis during the operating mode, wherein a drive train extends at least partially into the cable drum and is configured to drive the cable drum about the cable drum axis, and a motor is connected to and configured to power the drive train;

collecting, by a hoist controller, hoist operating data for the hoist assembly generated with the hoist assembly in the operating mode;

recalling, by the hoist controller, a maintenance parameter from a memory of the hoist controller;

comparing, by the hoist controller, the hoist operating data and the maintenance parameter;

determining, by the hoist controller, a maintenance task status based on the comparison of the hoist operating data and the maintenance parameter;

spooling the cable onto the cable drum and exiting the operating mode of the hoist assembly;

entering, by the hoist controller, a maintenance mode of the hoist assembly after exiting the operating mode of the hoist assembly and based on the hoist controller receiving a maintenance mode command; and

initiating, by the hoist controller, a maintenance routine for the maintenance task based on the maintenance task status; wherein the hoist assembly is mounted to an aircraft, wherein the operating mode occurs during flight, and wherein the maintenance mode is entered with the aircraft on the ground.

2. The method of claim 1 , further comprising:

providing access, by the hoist controller, to the maintenance routine by a user interface device.

3. The method of claim 2 , further comprising:

determining, by the hoist controller, a task completion status of the maintenance routine; and

exiting, by the hoist controller, the maintenance mode based on the task completion status being of a successful maintenance task.

4. The method of claim 3 , further comprising:

recording, by the hoist controller, the task completion status of the maintenance routine in a memory of the hoist controller.

5. The method of claim 1 , further comprising:

providing access, by the hoist controller, to the maintenance routine by the user interface device; and

determining, by the hoist controller, a task completion status of the maintenance routine.

6. The method of claim 1 , wherein the maintenance parameter is a temporal parameter.

7. The method of claim 1 , wherein the maintenance parameter is an operating parameter.

8. The method of claim 1 , wherein:

the maintenance task status is that the maintenance task is required based on the operating data being at least equal to the maintenance parameter; and

the maintenance task status is that the maintenance task is not required based on the operating data being less than the maintenance parameter.

9. The method of claim 1 , wherein the step of collecting, by the hoist controller, operating data regarding the hoist assembly comprises:

monitoring, with a sensor, operation of the rescue hoist assembly;

generating, with the sensor, the operating data;

receiving the operating data at the hoist controller; and

recording, by the hoist controller, the operating data in a memory of the hoist controller.

10. A hoist system comprising:

an aircraft;

a hoist assembly mounted on the aircraft, the hoist assembly comprising:

a cable drum;

a drive train; and

a motor connected with the drive train and configured to rotatably drive the cable drum via the drive train; and

a hoist controller configured to:

collect hoist operating data from one or more sensors with the hoist assembly in an operating mode;

compare the hoist operating data to a maintenance parameter stored in a memory of the hoist controller; and

determine a maintenance task status based on the comparison of the hoist operating data and the maintenance parameter;

exit the operating mode and enter a maintenance mode based on the hoist controller receiving a maintenance mode command and with the aircraft grounded; and

initiate a maintenance routine for the maintenance task based on the maintenance mode command and the maintenance task status.

11. The rescue hoist of claim 10 , wherein the maintenance parameter is a temporal parameter.

12. The rescue hoist of claim 10 , wherein the maintenance parameter is an operating parameter.

13. The rescue hoist of claim 10 , wherein the hoist controller is further configured to determine a task completion status of the maintenance routine.

14. The rescue hoist of claim 13 , wherein the hoist controller is further configured to provide access to the maintenance routine by a user interface device.

15. A method comprising:

collecting, by a hoist controller, hoist operating data for a hoist assembly generating with the hoist assembly in an operating mode during which the hoist assembly deploys and retrieves a cable from a cable drum;

comparing, by a hoist controller, hoist operating data generating during the operating mode with at least one maintenance parameter, the hoist assembly having the cable drum rotatable about a cable drum axis, a drive train extending at least partially into the cable drum and configured to drive the cable drum about the cable drum axis, and a motor connected to and configured to power the drive train;

determining, by the hoist controller and based on the comparison of the hoist operating data and the at least one maintenance parameter, a first maintenance status of a first maintenance task;

entering, by the hoist controller, a maintenance mode of a rescue hoist after exiting the operating mode and based on the hoist controller receiving a maintenance mode command;

initiating, by the hoist controller and based on the first maintenance status of the first maintenance task, a first maintenance routine for the first maintenance task; and

determining, by the hoist controller, a first task completion status; wherein the hoist assembly is mounted to an aircraft, wherein the operating mode occurs during flight, and wherein the maintenance mode is entered with the aircraft on the ground.

16. The method of claim 15 , further comprising:

providing access, by the hoist controller, to the first maintenance routine by a user interface device.

17. The method of claim 15 , further comprising:

exiting, by the hoist controller, the maintenance mode based on the first task completion status of the first maintenance routine being of a successful maintenance task.

18. The method of claim 15 , further comprising:

initiating, by the hoist controller, the first maintenance routine based on the first task completion status being of an unsuccessful maintenance task.

19. The method of claim 15 , further comprising:

determining, by the hoist controller and based on the comparison of the hoist operating data and the at least one maintenance parameter, a second maintenance status of a second maintenance task;

initiating, by the hoist controller and based on the second maintenance status of the second maintenance task, a second maintenance routine for the second maintenance task; and

determining, by the hoist controller, a second task completion status.
