This specific report is intended for use in cases where one flight deck effect is to be correlated with multiple faults. Identifier is a name identifying the set or sequence, identifier names must begin with a lowercase letter.

ARINC – Wikipedia

These events may be due to design errors, software errors, real but unusual events or misunderstanding of system design and operation. Therefore, in addition arlnc the actual maintenance function, the OMS should provide service reports on systems where sensors are available for normal operation, or where the addition of suitable sensors is economically feasible for this purpose. Arknc trends determined from this data can be used to monitor the health of systems that are subject to degradation.

Flight legs should be identified as: Ground tests should be enabled by selections via the OMS user interface.

Onboard Maintenance Systems Design & Development – Performance

Diagrams would not normally be used for ramp turnaround, but are useful for overnight maintenance when an airplane arijc to be removed from service and repaired in order to dispatch. Some OMS wordstrings e.

Activities of ARINC include the operation of an extensive system of domestic and overseas aeronautical land radio stations, the fulfillment of systems requirements to accomplish ground and airborne adinc, the allocation and assignment of frequencies to meet those needs, the coordination incident to standard airborne communications and electronics systems and the exchange of technical information. The degradation data should be made available to the ACMS.


This class is not referenced directly in the ASN. If an existing fault is cleared, this also should be reported to the CMC immediately. Specific design consideration should be given to system areas such as: If there is no response received from the LRU, fault should be reported.

Condition monitoring is also intended to provide data that will enable an airline to analyze its overall airplane fleet operation, thus improving its operating efficiency. Users may also find this information helpful in standardizing maintenance planning and procedures, and in securing appropriate recognition for such procedures from the regulatory agencies.

Typical candidates for service reports are engine oil quantity, hydraulic quantity, oxygen system, tire pressures, and others. It involves a connection between two systems that allows electrical or optical signals to be exchanged between them. To some, BITE means the unique hardware installed only for maintenance. Fault tolerance is the built-in capability of a system or LRU to continue to perform its required functions with a specified number of faults.

To provide for maximum flexibility, this could even be a customer option. Appendix B shows an example Present Leg Failures display. August 30, Private: The OMS designer should ensure that the proper manual troubleshooting procedures are automatically made available from applicable OMD data. The Transport Layer is responsible for providing 264 reliable, transparent transfer of data between end points, and provides end-to-end error recovery and flow control.

This will have the effect of reducing time and logistics needs for airplane maintenance. To provide a cost-effective, user friendly means of airplane maintenance.

The first is an integer indicating the test being run. Therefore, some modification will have to be made if a single CMC configuration is applied. If there is not any fault history to be reported for the block requested by the CMC, the member system should transmit a null history message. Hardware and Software Configuration Identification The operator may select specific tests, as provided for by the OMS menu and instruction displays.


This timing requirement should be the same as that for acknowledgment. Data in this document is used to determine airplane dispatch status, and to provide approved guidance on how to work around problems that cannot be immediately repaired in order to allow dispatch. This capability should be provided in a manner which does not interfere with normal operation of any other functions of the system. This area is being addressed by the suppliers by incorporating components with greater reliability, and utilizing faulttolerant designs.

Faults associated with a flight deck effect should not be cleared. Engine Start The time interval from the initiation of engine start e. Therefore, in addition to the actual maintenance function, the OMS should provide service reports on systems where sensors are available for normal operation, or where the addition of suitable sensors is economically feasible for this purpose. Currently two kinds of implementations are identified as follows: The display format should be consistent with that for other OMS functions.

Each user must be allowed to provide customization features in order to perform individual engineering analysis. August 30, ASN. The CMC should provide an Event command as either a broadcast or an equipment specific signal on the digital bus. It also provides for more consistent screen formats from one system to another.

Onboard Maintenance Systems for Modern Aviation

Particular care should be taken when storing faults during the power-on phase. Type number identifies the assigned context-specific type number, c. When appropriate criteria have been met, the OMS should respond to a data retrieval request if OMS data is to be dumped. A block should consist of 1 flight leg header and N fault records.
