The centralized interface between the aircraft and maintenance technician for the pc, 12 ng aircraft, the remote terminal, function, interface and connection was previously outlined in part. One of this presentation: 第一, we will review the maintenance message, function and usage for fall. Isolation, select the maintenance messages from the cmc remote terminal main menu. The active maintenance messages function should be utilized for assistance in troubleshooting, active or hard faulted items and their associated cast messages. 在此示例中, we are noting an mmdr 1 caution, cast message: select the drop down for the mmdr cast message and select the cmc active fault associated note. The fault name possible, lru at fault listed as well as the fault code associated. This fault code may be used in conjunction with the honeywell flight line maintenance manual for the pilatus pc1247e to assist in fault isolation. 下一个, we will review the maintenance message time order view function, select the time order, view function, then the applicable date range for fault inquiry. The time order view can be utilized to review log faults in a selected date range to assist in fall, isolation for intermittent or previously logged faults. Note the faults in bold white text enunciate an associated cast message that was visible to the flight crew. For this example, we are troubleshooting. A number two transponder fail cast message that was previously reported on february 20th and has since cleared note. The number two transponder fail caution logged on 220 and the related stored maintenance message.

Select the stored maintenance message. Note the possible lru’s at fault, as well as the fault code that should be used to determine fault in conjunction with the honeywell flight line maintenance manual for additional troubleshooting guidance. 下一个, we will review the system diagnostic selection. Note the ata selections available in system diagnostics. 在此示例中, we will continue with the number two transponder discrepancy and, as previously recommended by the noted fault in the flight line maintenance manual, we will conduct the number two transponder status check. 在此示例中. The number two transponder passed the status check, but the lru may be swapped with the number one side for additional monitoring and fault isolation. Continuing in system diagnostics, we want to review some non standard results. You may encounter during system tests and note these results as normal operation for the current cmcf version and aircraft platform. Note during the afcs aileron, elevator or rudo rudder servo loaded tests, valid results are only applicable for one test. During an aircraft power cycle, subsequent servo loaded tests during the same power cycle will result in failure of servo response. An additional non standard test result is noted during the air conditioning environmental control system, temperature control valve and flow control valve functional test note. The flow control valve end of travel fault will always be present with the current system configuration and should not be utilized as a legitimate indication of a flow control valve failure. An additional result to note during system diagnostic testing is the aiopa module reset test.

As the central maintenance computer function resides on this module performing, the reset test will result in your cmc, remote terminal, resetting and failing connection. There is a caution displayed in the remote terminal advising of this, 和, if performed, you will need to restart your cmc remote terminal program. 下一个, we will review the extended maintenance function. Member system status selection will allow you to view the current operational status of the associated member systems. This troubleshooting tool is useful to confirm the status of the member systems as being reported by gio and ascb data bus. The configuration selection under extended maintenance can be utilized to quickly identify applicable member system, lru part numbers serial numbers and current software part number. This tool is useful to quickly confirm lru information without the need for component removal and visual confirmation. The report selection under extended maintenance provides the ability to download and export aircraft acmf and fhdb files that can be utilized for trend, monitoring, exceedance, evaluation or as an additional troubleshooting tool. Note the acmf files may be downloaded as well as cleared while the fhdb can only be downloaded via the report selection and must be cleared via the setting selection in remote terminal, as outlined in the pc 12 ng aircraft maintenance manual chapter 45.. The final selection in the cmc remote terminal is the data loader selection. The dls tool, provides the ability to load required system software as well as recurrent database loading. The data loader function will be covered in detail in subsequent presentations.
