The invention claimed is: 1. A system for maintaining pieces of equipment housed in a vehicle wherein the pieces of equipment have means arranged so as to monitor the operation thereof, which monitoring means are connected to a recording unit, characterized in that the monitoring means for at least one of the pieces of equipment are arranged so as to monitor the execution of software incorporated in the equipment and detect occurrences of fault conditions and/or fault symptoms and the recording unit recording at least one of state and variable values pertaining to the detected fault condition and/or fault symptom and the address for the portion of code for the software where the fault condition and/or fault symptom occurred when the occurrences of fault conditions and/or fault symptoms are detected and where the address for the portion of code for the software is gathered for recording by the monitoring means. 2. The system according to claim 1, characterized in that it contains a software maintenance organization located outside of the vehicle and arranged so as to process the recording in order to create updated software for the piece of equipment. 3. The system according to claim 1, characterized in that the vehicle is an aircraft. 4. The system according to claim 1, characterized in that the monitoring means are arranged so as to monitor whether pre-determined criteria are being met for the software. 5. The system according to claim 1, characterized in that the monitoring means are arranged so as to monitor whether correlations required for proper function are in effect. 6. The system according claim 1, characterized in that the monitoring means are integrated with their respective software. 7. The system according to claim 1, characterized in that the recording contains localization information and variable values relevant to their associated fault condition and/or fault symptom. 8. The system according to claim 1, characterized in that the recording unit contains a memory unit arranged so as to save the recording. 9. The system according to claim 1, characterized in that the vehicle contains a real-time system. 10. A method for performing maintenance in a vehicle, in which the operation of one or more pieces of equipment housed in the vehicle is monitored, characterized in that, for at least one of the pieces of equipment, the execution of software incorporated in the equipment is monitored and occurrences of fault conditions and/or fault symptoms are detected and at least one of state and variable values pertaining to the detected fault condition and/or fault symptom and the address for the portion of code for the software where the fault condition and/or fault symptom occurred is recorded when the occurrences of fault conditions and/or fault symptoms are detected and where the address for the portion of code for the software is gathered for recording by the monitoring means. 11. The method according to claim 10, characterized in that it contains a software maintenance organization located outside of the vehicle and arranged so as to process the recording in order to create updated software for the piece of equipment. 12. The system according to claim 10, characterized in that the vehicle is an aircraft.
