Minimum equipment list systems for aircraft
An automated minimum equipment list (MEL) system for an aircraft can include a control module operatively connected to a plurality of aircraft components. The control module can be configured to receive information relating to the plurality of aircraft components, and determine that one or more inoperative components exist in the plurality of aircraft components based on the information relating to the plurality of aircraft components. The control module can be configured to automatically determine whether one or more MEL dispatch conditions exist based on a stored MEL and the one or more inoperative components. The control module can be configured to control at least one of the plurality of aircraft components to configure the plurality of aircraft components to comply with at least one MEL dispatch condition if one or more MEL dispatch conditions exist to allow the aircraft to dispatch with the one or more inoperative components.
1 . An automated minimum equipment list (MEL) system for an aircraft, comprising:
a control module operatively connected to a plurality of aircraft components and configured to:
receive information relating to the plurality of aircraft components;
determine that one or more inoperative components exist in the plurality of aircraft components based on the information relating to the plurality of aircraft components;
automatically determine whether one or more MEL dispatch conditions exist based on a stored MEL and the one or more inoperative components;
generate a user interface that indicates the one or more MEL dispatch conditions and displays a status of the one or more inoperative components; and
control at least one of the plurality of aircraft components to configure the plurality of aircraft components to comply with at least one MEL dispatch condition once one or more MEL dispatch conditions exist to allow the aircraft to dispatch with the one or more inoperative components.
2 . The system of claim 1 , wherein the plurality of aircraft components includes one or more electrical breakers.
3 . The system of claim 2 , wherein the one or more electrical breakers include one or more solid state power controllers (SSPCs).
4 . The system of claim 2 , wherein the control module is configured to detect an open state of the one or more electrical breakers, a trip state of the one or more electrical breakers, a fail state of the one or more electrical breakers, and/or a failed state of a respective load connected to the one or more electrical breakers.
5 . The system of claim 2 , wherein the control module is configured to detect that at least one of the one or more circuit electrical breakers is in a tripped position.
6 . The system of claim 2 , wherein the control module is configured to detect that a user commanded an out/lock position of at least one of the one or more electrical breakers.
7 . The system of claim 2 , wherein the control module is configured to detect that at least one of the one or more electrical breakers failed open.
8 . The system of claim 2 , wherein the control module is configured to detect that load current data associated with at least one of the one or more electrical breakers is below a minimum expected threshold.
9 . The system of claim 2 , wherein the user interface is configured for user selection and/or confirmation of the one or more MEL dispatch conditions before controlling the at least one of the plurality of aircraft components.
10 . The system of claim 9 , wherein the user interface is further configured to display a status of one or more relevant electrical breakers of the one or more electrical breakers associated with a selected MEL dispatch condition.
11 . The system of claim 1 , wherein the control module is configured such that, if at least one MEL dispatch condition does not exist, the control module outputs an alert indicating that the aircraft cannot dispatch.
12 . The system of claim 1 , wherein the stored MEL comprises an operator MEL or a master MEL.
13 . A control module for an automated minimum equipment list (MEL) system of an aircraft, the control module comprising a non-transitory computer readable medium configured to store computer executable instructions to perform a method, the method comprising:
receiving information relating to a plurality of aircraft components;
determining that one or more inoperative components exist in the plurality of aircraft components based on the information relating to the plurality of aircraft components;
automatically determining whether one or more MEL dispatch conditions exist based on a stored MEL and the one or more inoperative components;
generating a user interface that indicates the one or more MEL dispatch conditions, wherein the user interface is configured for user selection and/or confirmation of the one or more MEL dispatch conditions; and
controlling at least one of the plurality of aircraft components to configure the plurality of aircraft components to comply with at least one MEL dispatch condition once one or more MEL dispatch conditions exist to allow the aircraft to dispatch with the one or more inoperative components.
14 . The control module of claim 13 , wherein the plurality of aircraft components includes one or more electrical breakers.
15 . The control module of claim 14 , wherein the one or more electrical breakers include one or more solid state power controllers (SSPCs).
16 . The control module of claim 14 , wherein determining that the one or more inoperative components exist includes detecting open state of the one or more electrical breakers, a trip state of the one or more electrical breakers, a fail state of the one or more electrical breakers, and/or a failed state of a respective load connected to the one or more electrical breakers.
17 . The control module of claim 14 , wherein determining that the one or more inoperative components exist includes detecting that at least one of the one or more electrical breakers is in a tripped position.
18 . The control module of claim 14 , wherein determining that the one or more inoperative components exist includes detecting that a user commanded an out/lock position of at least one of the one or more electrical breakers.
19 . The control module of claim 14 , wherein determining that the one or more inoperative components exist includes detecting that at least one of the one or more electrical breakers failed open.
20 . A method, comprising:
receiving information relating to a plurality of aircraft components;
determining that one or more inoperative components exist in the plurality of aircraft components based on the information relating to the plurality of aircraft components;
automatically determining whether one or more MEL dispatch conditions exist based on a stored MEL and the one or more inoperative components;
generating a user interface that indicates the one or more MEL dispatch conditions and displays a status of the one or more inoperative components, wherein the user interface is configured for user selection and/or confirmation of the one or more MEL dispatch conditions; and
controlling at least one of the plurality of aircraft components to configure the plurality of aircraft components to comply with at least one MEL dispatch condition once one or more MEL dispatch conditions exist to allow an aircraft to dispatch with the one or more inoperative components.
