Abstract

There is provided herein an aircraft including at least one aircraft galley container and a controller. Each one of the at least one aircraft galley container includes a safety feature having a first mode and a second mode, and a controller for automatically selecting one of the first mode and second mode of the safety feature and placing the safety feature in the selected mode. The automatic selection of the mode is dependent on a condition of the aircraft satisfying or failing to satisfy a predetermined condition. There is also provided a method of operating a safety feature of an aircraft galley container.

First claim

What is claimed is:

1 . An aircraft comprising:
at least one aircraft galley container, each one of the at least one aircraft galley container including a safety feature having a first mode and a second mode; and a controller for automatically selecting one of the first mode or the second mode of the safety feature and placing the safety feature in a selected mode, wherein the automatic selection of the first mode or the second mode is dependent on a condition of the aircraft satisfying or failing to satisfy a predetermined condition, wherein each of the at least one aircraft galley container comprises:
a door;
a latch mechanism, wherein the latch mechanism is positionable in a latched position preventing opening of the door and an unlatched position permitting opening of the door, wherein the latch mechanism includes:
a handle;
a pair of rods; and
a rotatable plate coupled to the handle and configured to be rotated by the handle and to convert rotational movement of the handle to linear movement of the pair of rods to place the latch mechanism in the latched and unlatched positions; and
a lock configured to selectively prevent the rotatable plate from rotation to maintain the latch mechanism in the latched position,
wherein the lock comprises a locking member,
wherein the rotatable plate comprises a recess shaped to conform to the locking member,
wherein, in a locked position, the lock prevents the rotatable plate from rotation by the locking member engaging with the recess, and
wherein, in an open position, the lock permits the rotatable plate to rotate by the locking member disengaging with the recess.

2 . The aircraft of claim 1 , wherein the at least one aircraft galley container includes a plurality of aircraft galley containers.

3 . The aircraft of claim 1 , wherein the the latch mechanism is a remotely operable latch mechanism, wherein the first mode includes the locked position of the latch mechanism and the second mode includes the open position of the latch mechanism.

4 . The aircraft of claim 3 , wherein the predetermined condition includes a predetermined set of geographical locations of the aircraft.

5 . The aircraft of claim 3 , wherein the predetermined condition includes a flight state including docked, taxiing, take-off, climb, descent, landing, and cruise states, wherein the predetermined condition is satisfied when the aircraft is in one of the taxiing, take-off, climb, descent, and landing states and the predetermined condition is not satisfied during the docked and the cruise states.

6 . The aircraft of claim 1 , wherein the at least one aircraft galley container is an oven and the safety feature includes a self-cleaning module for the oven, wherein the first mode includes the self-cleaning module being operable and the second mode includes the self-cleaning module being inhibited.

7 . The aircraft of claim 6 , wherein the predetermined condition includes a turbulence threshold of the aircraft.

8 . The aircraft of claim 1 , further including a sensor for determining which mode the safety feature is in, and a display module for indicating to a user which mode the safety feature is in.

9 . The aircraft of claim 1 , comprising a manual input configured to override the controller when a user provides an input signal.

10 . A method of operating at least one safety feature associated with a respective at least one aircraft galley container, the method comprising:
determining whether an aircraft satisfies a predetermined condition; responsive to aircraft satisfying the predetermined condition, placing a safety feature of at least one aircraft galley container in a first mode, wherein in the first mode, a lock prevents a rotatable plate from rotation by a locking member engaging with a recess in the rotatable plate; and responsive to aircraft failing to satisfy the predetermined condition, placing the at least one safety feature of the at least one aircraft galley container in a second mode, wherein, in the second mode, the lock permits the rotatable plate to rotate by the locking member disengaging with the recess in the rotatable plate.

11 . The method of claim 10 , wherein the at least one aircraft galley container includes a plurality of aircraft galley containers, and the steps of placing the at least one safety feature of the at least one aircraft galley container in the first mode and the second mode includes placing safety features of each of the plurality of aircraft galley containers in the first mode and the second mode respectively.

12 . The method of claim 10 , wherein the at least one safety feature includes a remotely operated locking arrangement, the first mode includes a locked condition of the remotely operated locking arrangement, and the second mode includes an open condition of the remotely operated locking arrangement.

13 . The method of claim 12 , wherein the predetermined condition includes a set of geographical locations of the aircraft.

14 . The method of claim 10 , wherein the at least one aircraft galley container is an oven and the at least one safety feature includes a self-cleaning module for the oven, wherein the first mode includes the self-cleaning module being on and the second mode includes the self-cleaning module being off, wherein the predetermined condition includes turbulence threshold of the aircraft.
