Abstract

A system, a method, and a computer program are provided for recording technical issues of an aircraft. A server unit is adapted to store and output data related to technical issues of an aircraft. A client unit sends an access request to a server, which receives and processes this request, permits access to the data and restricts the adding or modifying processing of the data to one client unit at a time. For use during flight tests on board of the aircraft, a snapshot of the data may be transferred to a mobile computer, while the data on the server unit is restricted to read-only. After the flight test, the modified data is transferred back to the server unit and the read-only restriction is removed.

Claims

1. A system for recording technical issues of an aircraft, the system comprising:

a ground-based server unit that stores and outputs data related to the technical issues of the aircraft; and

a mobile client unit that sends an access request to the server unit to access and process the data,

wherein the server unit further;

receives and processes the access request from the client unit;

permits access to the data by transferring a snapshot of the data related to the aircraft to the client unit, wherein the client unit that modifies the snapshot of data during a flight test;

locks the data on the server unit for the aircraft to a single client unit at a time until the client unit transfers the modified snapshot of the data back to the server unit,

wherein the server unit receives the modified snapshot of the data related to the aircraft from the client unit after usage during the flight test.

2. The system according to claim 1, wherein the server unit is adapted to restrict the access to the data to read-only after the snapshot of the data has been transferred to the client unit and before the modified snapshot of data has been transferred back to the server unit after the flight test.

3. The system according to claim 1, wherein the client unit is a mobile computer.

4. The system according to claim 1, wherein the client unit is a workstation that is dedicated to a workplace in a flight test line for the aircraft.

5. The system according to claim 1, wherein the server unit is adapted to restrict the access to the data according a user permission.

6. A method for recording technical issues of an aircraft, said method comprising:

sending an access request from a mobile client unit to a ground-based server unit to access and process data that is a snapshot of data related to a technical issue of the aircraft;

receiving and processing the access request from the client unit by the server unit;

permitting access to the data by transferring a snapshot of the data related to the aircraft to the client unit, wherein the client unit that modifies the snapshot of data during a flight test;

locking the data on the server unit for the aircraft to a single client unit at a time until the client unit transfers the modified snapshot of the data back to the server unit; and

receiving the modified snapshot of the data related to the aircraft on the server unit from the client unit after usage during the flight test.

7. The method according to claim 6,

wherein a dataset for storing information about technical issues of the aircraft in the server unit at the beginning of a flight testing program is created;

and

wherein the dataset is closed after finishing the flight testing program.

8. The method according to claim 6, wherein the server unit sets a dataset to a read-only state after sending to the client unit, and after the client unit sends the modified snapshot of data back to the server unit, the server unit removes the read-only state from the dataset.

9. A non-transitory computer readable medium embodying a computer program product, said computer program product comprising:

a program for recording technical issues of an aircraft, the program for recording the technical issues of the aircraft configured to;

send an access request from a client unit to a server unit to access and process data related to a technical issue of the aircraft;

permit access to the data by transferring a snapshot of the data related to the aircraft to the client unit, wherein the client unit that modifies the snapshot of the data during a flight test;

lock the data on the server unit for the aircraft to a single client unit at a time until the client unit transfers the modified snapshot of the data back to the server unit; and

receive the modified snapshot of the data related to the aircraft from the client unit after usage during the flight test.

10. The non-transitory computer readable medium embodying the computer program product according to claim 9, wherein the program is further configured to restrict the access to the data to read-only after the snapshot of the data has been transferred to the client unit and before the modified snapshot of the data has been transferred back to the server unit after the flight test.

11. The non-transitory computer readable medium embodying the computer program product according to claim 9, wherein the program is further configured to restrict access to the data according a user permission.
