Abstract

There is described a method for maintenance of an aircraft component, the method comprising: connecting electrically to the aircraft component via a maintenance terminal; retrieving maintenance data relating to the aircraft component using the maintenance terminal; performing maintenance operations on the aircraft component by entering data via a user interface on the maintenance terminal; and communicating in real time with a remote operator by transmitting and receiving at least one of voice signals and data signals wirelessly across a network via the maintenance terminal while performing the maintenance operations.

Claims

1. A method for maintenance of an aircraft engine, the method comprising:

retrieving maintenance data relating to the aircraft engine being maintained using a portable data transmission unit positioned adjacent the aircraft engine and having an electrical connection therewith, said data transmission unit part of an on-board engine performance monitoring system of the aircraft and configured to capture in real time performance data indicative of a performance of the aircraft engine and to make the performance data available for analysis upon landing of the aircraft;

performing maintenance operations on the aircraft engine directly through the data transmission unit using data entered via a user interface integrated with said data transmission unit and said maintenance data accessed through said user interface; and

communicating in real time with a remote operator directly from the aircraft engine being maintained using said data transmission unit, said communicating performed by transmitting and receiving at least one of voice signals and data signals wirelessly across a network, said signals transmitted and received directly through said data transmission unit while performing said maintenance operations.

2. A method as claimed in claim 1, further comprising accessing at least one remote database from said data transmission unit via said network to retrieve information for said maintenance operations.

3. A method as claimed in claim 1, wherein said communicating comprises communicating with a help desk operator to obtain assistance for said maintenance operations.

4. A method as claimed in claim 1, wherein said communicating comprises enabling a connection by pushing a single button on said maintenance terminal.

5. A method as claimed in claim 1, wherein said communicating comprises speaking into said maintenance terminal and receiving text from said remote operator.

6. A method as claimed in claim 1, wherein said communicating comprises speaking into said data transmission unit and receiving voice signals from said remote operator.

7. A method for maintenance of an aircraft engine, the method comprising:

initiating communication with a remote operator directly from the aircraft engine being maintained via a portable data transmission unit, said data transmission unit positioned adjacent the aircraft engine and electrically connected thereto, said data transmission unit part of an on-board engine performance monitoring system of the aircraft and configured to capture in real time performance data indicative of a performance of the aircraft engine and to make the performance data available for analysis upon landing of the aircraft;

retrieving maintenance data from the aircraft engine via said data transmission unit;

receiving input data via a user interface integrated with said data transmission unit;

performing maintenance operations on the aircraft engine directly through the data transmission unit using said input data and said maintenance data; and

communicating in real time with said remote operator from said data transmission unit by transmitting and receiving voice signals and data signals wirelessly across a network while performing said maintenance operations.

8. A method as claimed in claim 7, further comprising accessing at least one remote database from said data transmission unit via said network to retrieve information for said maintenance.

9. A method as claimed in claim 7, wherein said transmitting and receiving voice signals and data signals comprises converting a voice signal into a data signal and transmitting said data signal to said remote operator.

10. A method as claimed in claim 7, wherein said transmitting and receiving voice signals and data signals comprises receiving a data signal from said remote operator and converting said data signal into a voice signal.
